利用ASP.NET MVC+EasyUI+SqlServer搭建企业开发框架
数据库 / 管理员发布于 5年前 283

我们要搭建的框架是企业级开发框架，适用用企业管理信息系统的开发，如：OA、HR等

1、框架名称：sampleFrame。

2、搭建原则：最少知识原则。

3、先定义一个简单的编码规范：除类名和接口名外，其余首字母小写。

4、准备开发环境：vs2010及以上（mvc4）、sqlserver、jquery2.0和easyui1.4.5

首先来看一下列表页面的效果图：

我们期望简洁带前台代码，如下：

<table id="dataGrid" class="easyui-datagrid" url="getList" toolbar="#toolbar"> <thead> <tr>  <th field="customerId" sortable="true" data-options="sortable:true" width="50">  customerId  </th>  <th field="companyName" data-options="sortable:true" width="50">  companyName  </th>  <th field="phone" width="50">  phone  </th>  <th field="address" width="50">  address  </th> </tr> </thead></table><div id="toolbar"> <div> <a class="easyui-linkbutton" iconcls="icon-add" onclick="add();">添加</a> <a class="easyui-linkbutton" iconcls="icon-edit" onclick="edit();">修改</a> <a class="easyui-linkbutton" iconcls="icon-remove" onclick="del();">删除</a> </div> <div> <input id="queryBox" class="easyui-textbox" buttonicon="icon-search" style="width: 200px;"  data-options="onClickButton:function(){loadList(loadListSettings);}" /> <a class="easyui-linkbutton" iconcls="icon-find" onclick="showQueryWindow();">  详细查询</a> </div></div><script type="text/javascript"> var loadListSettings = { searchFields: "customerId,companyName", prompt: "请输入客户Id或公司名称" };</script><script type="text/javascript"> pageInit(); </script>

为了这样简洁的前台，我们需要准备：

1、通用的布局模板_Layout.cshtml。base.css、base.js、defaultSettings.js、tool.js和private.js见后面

<!doctype html><html><head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width" /> <meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1" /> <link href='https:webResource/easyui/themes/default/easyui.css' rel='stylesheet' type='text/css' /> <link href='https:webResource/easyui/themes/icon.css' rel='stylesheet' type='text/css' /> <link href='https:webResource/base.css' rel='stylesheet' type='text/css' /> <script src="https:webResource/jquery/jquery.min.js" type="text/javascript"></script> <script src="https:webResource/jquery/json2.js" type="text/javascript"></script> <script src="https:webResource/easyui/jquery.easyui.min.js" type="text/javascript"></script> <script src="https:webResource/easyui/locale/easyui-lang-zh_CN.js" type="text/javascript"></script> <script src="https:webResource/tool.js" type="text/javascript"></script> <script src="https:webResource/base.js" type="text/javascript"></script> <script src="https:webResource/defaultSettings.js" type="text/javascript"></script> <script src="https:webResource/private.js" type="text/javascript"></script> @RenderSection("scripts", required: false)</head><body style="width: 100%; height: 100%; margin: 0px;"> @RenderBody()</body></html>

2、平台样式表base.css

.icon-find{ background: url('icons/find.png') no-repeat center center;}.datagrid-toolbar div:nth-child(1){ float: left; width: 60%;}.datagrid-toolbar div:nth-child(2){ margin-left: 60%; margin-right: 10px; width: auto; text-align: right;}

3、基本方法脚本base.js

//取消自动渲染$.parser.auto = false;function pageInit() { //改变控件默认值 $.fn.linkbutton.defaults.plain = true; $.fn.datagrid.defaults.fit = true; $.fn.datagrid.defaults.fitColumns = true; $.fn.datagrid.defaults.pagination = true; //显示ajax异常信息 $(document).ajaxError(function (event, xhr, options, exc) { $.messager.alert({ title: '异步请求出错', msg: xhr.responseText, icon: "error" }); }); //地址栏传参允许中文 jQuery(document).ajaxSend(function (event, request, options) { options.url = encodeURI(options.url); }); $.parser.parse();}function loadList(settings) { var settings = $.extend(true, {}, loadListDefaultSettings, settings); if ($("#" + settings.gridId).length == 0) $.messager.alert({ title: "系统异常", msg: "DataGrid：" + settings.gridId + "不存在！", icon: "error" }); var quickQueryData = []; if ($("#" + settings.queryBoxId).length > 0) { var val = $("#" + settings.queryBoxId).textbox("getValue"); if (settings.searchFields && val) {  var keys = settings.searchFields.split(',');  for (i = 0, len = keys.length; i < len; i++) {  quickQueryData.push({ field: keys[i], method: 'inLike', value: val });  } } } var queryData = []; //详细查询预留  //加载数据 $("#" + settings.gridId).datagrid("load", { quickQueryData: JSON.stringify(quickQueryData), queryData: JSON.stringify(queryData) });}

4、基本脚本默认值defaultSettings.js

//查询参数设置var loadListDefaultSettings = { url: "getList", gridId: "dataGrid", queryWindowId: "queryWindow", queryBoxId: "queryBox", searchFields: "Name", addQueryString: true, prompt: "请输入"};5、可能需要使用的工具方法tool.js//判断是否包含地址栏参数function hasQueryString(key, url) { if (typeof (url) == "undefined") url = window.location.search; var re = new RegExp("[?&]" + key + "=([^\\&]*)", "i"); var a = re.exec(url); if (a == null) return false; return true;}//获取地址栏参数,如果参数不存在则返回空字符串function getQueryString(key, url) { if (typeof (url) == "undefined") url = window.location.search; var re = new RegExp("[?&]" + key + "=([^\\&]*)", "i"); var a = re.exec(url); if (a == null) return ""; return a[1];}//将当前地址栏参数加入到urlfunction addUrlSearch(url) { var newParams = []; var paramKeys = window.location.search.replace('?', '').split('&'); for (var i = 0; i < paramKeys.length; i++) { var key = paramKeys[i].split('=')[0]; if (key == "" || key == "_t" || key == "_winid" || key == "isTab")  continue; if (!hasQueryString(key, url))  newParams.push(paramKeys[i]); } if (url.indexOf('?') >= 0) return url + "&" + newParams.join('&'); else return url + "?" + newParams.join('&');}//url增加参数function addSearch(url, key, value) { if (!hasQueryString(key, url)) { if (url.indexOf('?') >= 0)  return url + "&" + key + "=" + value; else  return url + "?" + key + "=" + value; } else return url;}//获取数组中对象的某个值，逗号分隔function getValues(rows, attr) { var fieldValues = []; for (var i = 0; i < rows.length; i++) { if (rows[i] != null)  fieldValues.push(rows[i][attr]); } return fieldValues.join(',');}

6、可能需要使用的私有方法private.js，此文件包含的方法专供base.js使用，开发web时禁止使用

//替换掉Url中的{}参数function replaceUrl(settings, pty) { if (!pty) pty = "url"; if (!settings[pty]) return; var str = settings[pty]; var guid = ""; var result = str.replace(/\{[0-9a-zA-Z_]*\}/g, function (e) { var key = e.substring(1, e.length - 1); if (key == "GUID") {  if (!guid) {  $.ajax({   url: "getGuid",   type: "post",   async: false,   success: function (text, textStatus) {   guid = text;   }  });  }  return guid; } if (hasQueryString(key)) //从地址栏返回  return getQueryString(key); if (settings.currentRow && settings.currentRow[key])//从当前行返回  return settings.currentRow[key]; if (settings.paramFrom) { //从指定控件返回  var ctrl = mini.get(settings.paramFrom);  if (ctrl == undefined) {  $.messager.alert({ title: 'UI出错', msg: "Id为" + settings.paramFrom + "的控件不存在！", icon: "error" });    return;  }  else if (ctrl.showCheckBox) {  return getValues(ctrl.getCheckedNodes(), key);  }  else if (ctrl.getSelecteds)  return getValues(ctrl.getSelecteds(), key);  else if (ctrl.getValue)  return ctrl.getValue(); } return e; }); settings[pty] = result; return result;}//转化为全路径function changeToFullUrl(settings) { var url = settings.url; if (url.indexOf('/') == 0 || url.indexOf("http://") == 0 || url.indexOf('?') == 0 || url == "") return url; currentUrlPathName = window.location.pathname; var currentPathNameParts = currentUrlPathName.split('/'); var pathNameParts = url.split('?')[0].split('/'); if (currentPathNameParts[currentPathNameParts.length - 1] == "") currentPathNameParts.pop(); //去掉一个反斜线 if (pathNameParts[pathNameParts.length - 1] == "") pathNameParts.pop(); //去掉一个反斜线 var index = currentPathNameParts.length - 1; for (var i = 0; i < pathNameParts.length; i++) { if (pathNameParts[i] == "..") {  index = index - 1;  if (index <= 0) {  $.messager.alert({ title: "系统异常", msg: "Url错误：" + url + "！", icon: "error" });return;  }  continue; } if (index < currentPathNameParts.length)  currentPathNameParts[index] = pathNameParts[i]; else  currentPathNameParts.push(pathNameParts[i]); index = index + 1; } var length = currentPathNameParts.length; for (var i = index; i < length; i++) { currentPathNameParts.pop(); } var result = currentPathNameParts.join('/'); if (url.indexOf('?') > 0) result += url.substring(url.indexOf('?')); settings.url = result;}

我们期望简洁的后台代码，如下：

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using formula;using System.Data;namespace demo.Areas.basic.Controllers{ public class customerController : BaseController { public JsonResult getList(QueryBuilder qb) {  SqlHelper sqlHelper = new SqlHelper("demo");  var data = sqlHelper.ExecuteGridData("select *,id=customerId from customer", qb);  return Json(data); } }}

为了这种简洁的代码我们需要：

1、Controller基类BaseController：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Web.Mvc;using System.Data.Entity;using System.Data.SqlClient;using System.Data.Entity.Validation;using System.ComponentModel;using System.Reflection;using System.Web.Security;using formula;namespace formula{ public abstract class BaseController : Controller { #region 处理不存在的Action protected override void HandleUnknownAction(string actionName) {  if (Request.HttpMethod == "POST")  {  HttpContext.ClearError();  HttpContext.Response.Clear();  HttpContext.Response.StatusCode = 500;  HttpContext.Response.Write("没有Action:" + actionName);  HttpContext.Response.End();  }  // 搜索文件是否存在  var filePath = "";  if (RouteData.DataTokens["area"] != null)  filePath = string.Format("~/Areas/{2}/Views/{1}/{0}.cshtml", actionName, RouteData.Values["controller"], RouteData.DataTokens["area"]);  else  filePath = string.Format("~/Views/{1}/{0}.cshtml", actionName, RouteData.Values["controller"]);  if (System.IO.File.Exists(Server.MapPath(filePath)))  {  View(filePath).ExecuteResult(ControllerContext);  }  else  {  HttpContext.ClearError();  HttpContext.Response.Clear();  HttpContext.Response.StatusCode = 500;  HttpContext.Response.Write("没有Action:" + actionName);  HttpContext.Response.End();  } } #endregion #region 基类Json方法重载 protected override JsonResult Json(object data, string contentType, Encoding contentEncoding, JsonRequestBehavior behavior) {  NewtonJsonResult result = new NewtonJsonResult() { Data = data, ContentType = contentType, ContentEncoding = contentEncoding, JsonRequestBehavior = behavior };  return result; } protected override JsonResult Json(object data, string contentType, Encoding contentEncoding) {  NewtonJsonResult result = new NewtonJsonResult() { Data = data, ContentType = contentType, ContentEncoding = contentEncoding };  return result; } #endregion #region 异常处理 protected override void OnException(ExceptionContext filterContext) {  Exception exp = filterContext.Exception;  if (string.IsNullOrEmpty(exp.Message))  exp = exp.GetBaseException();  if (filterContext.RequestContext.HttpContext.Request.IsAjaxRequest())  {  var response = filterContext.RequestContext.HttpContext.Response;  response.Clear();  response.Write(exp.Message);  response.StatusCode = 500;  response.End();  } } #endregion }}

2、查询构造器QueryBuilder：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Collections;using System.Web.Mvc;namespace formula{ [ModelBinder(typeof(QueryBuilderBinder))] public class QueryBuilder : SearchCondition { public int page { get; set; } public int rows { get; set; } public string sort { get; set; } public string order { get; set; } public int total { get; set; } public string getOrderByString(bool hasOrderBy = true) {  var sortFields = this.sort.Split(',');  var sortOrders = this.order.Split(',');  string str = "";  for (int i = 0; i < sortFields.Length; i++)  {  str += sortFields[i] + " " + sortOrders[i] + ",";  }  if (hasOrderBy && str != "")  str = "order by " + str;  return str.Trim(','); } } public class SearchCondition { public string fields = "*"; private List<ConditionItem> quickItems = new List<ConditionItem>(); private List<ConditionItem> complexItems = new List<ConditionItem>(); public SearchCondition add(string field, string method, object val, bool isQuickSearch = false) {  //处理日期型数据  if (method == "<" || method == "<=")  {  if (val.GetType() == typeof(DateTime))  {   DateTime t = (DateTime)val;   val = t.Date.AddHours(23).AddMinutes(59).AddSeconds(59);  }  }  ConditionItem item = new ConditionItem(field, method, val);  if (isQuickSearch)  quickItems.Add(item);  else  complexItems.Add(item);  return this; } public string getWhereString(bool hasWhere = true) {  if (quickItems.Count == 0 && complexItems.Count == 0)  return "";  string strWhere = "";  if (quickItems.Count > 0)  strWhere += " and (" + getGourpWhereString(quickItems, true) + ")";  if (complexItems.Count > 0)  strWhere += " and (" + getGourpWhereString(complexItems, false) + ")";  if (hasWhere)  strWhere = " where " + strWhere.Substring(4);  else  strWhere = " and " + strWhere.Substring(4);  return strWhere; } #region 私有方法 private string getGourpWhereString(List<ConditionItem> list, bool isOrRelation = false) {  if (list.Count == 0)  return "";  string strWhere = "";  for (int i = 0; i < list.Count(); i++)  {  var item = list[i];  string str = item.getWhereString();  if (isOrRelation)  {   strWhere += " or " + str;  }  else  {   strWhere += " and " + str;  }  }  strWhere = strWhere.Substring(4);  return strWhere; } #endregion } public class ConditionItem { public ConditionItem(string field, string method, object val) {  this.field = field;  this.method = method;  this.value = val; } public string field { get; set; } public string method { get; set; } public object value { get; set; } public string getWhereString() {  var item = this;  switch (item.method)  {  case "=":  case "<":  case ">":  case "<=":  case ">=":  case "<>":   return string.Format("{0} {1} '{2}'", item.field, item.method, item.value);  case "in":   string v = "";   if (item.value is ICollection)   {   ICollection<string> collection = item.value as ICollection<string>;   v = string.Join("','", collection.ToArray<string>());   return string.Format("{0} in('{1}')", item.field, v);   }   else   {   v = item.value.ToString().Replace(",", "','");   }   return string.Format("{0} in ('{1}')", item.field, v);  case "between":   object[] objs = item.value as object[];   return string.Format("{0} between '{1}' and '{2}'", item.field, objs[0], objs[1]);  case "inLike":   string[] arr = null;   if (item.value is ICollection)   {   ICollection<string> collection = item.value as ICollection<string>;   arr = collection.ToArray<string>();   }   else   {   arr = item.value.ToString().Split(',', '，');   }   string str = "";   foreach (string s in arr)   {   str += string.Format("or {0} like '%{1}%'", item.field, s);   }   return "(" + str.Substring(3) + ")";  case "day":   DateTime dt = DateTime.Now;   if (!DateTime.TryParse(item.value.ToString(), out dt))   {   throw new BuessinessException("查询条件不能转化为日期时间");   }   string start = dt.Date.ToString("yyyy-MM-dd");   string end = dt.Date.AddDays(1).ToString("yyyy-MM-dd");   return string.Format("{0} between '{1}' and '{2}'", item.field, start, end);  case "startWith":   return string.Format("{0} like '{1}%'", item.field, item.value);  case "endWith":   return string.Format("{0} like '%{1}'", item.field, item.value);  default:   return "";  } } }}

3、查询构造器QueryBuilder的创建方法QueryBuilderBinder：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Web.Mvc;namespace formula{ public class QueryBuilderBinder : IModelBinder { public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) {  var qb = (QueryBuilder)(bindingContext.Model ?? new QueryBuilder());  var dict = controllerContext.HttpContext.Request.Params;  var quickQueryList = !string.IsNullOrEmpty(dict["quickQueryData"]) ? JsonHelper.ToList(dict["quickQueryData"]) : new List<Dictionary<string, object>>();  var queryList = !string.IsNullOrEmpty(dict["queryData"]) ? JsonHelper.ToList(dict["queryData"]) : new List<Dictionary<string, object>>();  foreach (var dic in quickQueryList)  {  var val = dic["value"].ToString();  if (val == "") continue;  qb.add(dic["field"].ToString(), dic["method"].ToString(), val, true);  }  foreach (var dic in queryList)  {  var val = dic["value"].ToString();  if (val == "") continue;  qb.add(dic["field"].ToString(), dic["method"].ToString(), val, false);  }   qb.page = !string.IsNullOrEmpty(dict["page"]) ? int.Parse(dict["page"].ToString()) : 1;  qb.rows = !string.IsNullOrEmpty(dict["rows"]) ? int.Parse(dict["rows"].ToString()) : 10;  qb.sort = !string.IsNullOrEmpty(dict["sort"]) ? dict["page"].ToString() : "id";  qb.order = !string.IsNullOrEmpty(dict["order"]) ? dict["order"].ToString() : "desc";  return qb; } }}

4、数据库查询帮助类SqlHelper：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Data.SqlClient;using System.Data;using System.Web;namespace formula{ public class SqlHelper { #region 构造函数 public SqlHelper(string connName) {  if (System.Configuration.ConfigurationManager.ConnectionStrings[connName] == null)  throw new BuessinessException(string.Format("配置文件中不包含数据库连接字符串：{0}", connName));  this.connName = connName;  this.connString = System.Configuration.ConfigurationManager.ConnectionStrings[connName].ConnectionString; } public string connName { get; private set; } public string connString { get; private set; } public string dbName {  get  {  SqlConnection conn = new SqlConnection(connString);  return conn.Database;  } } #endregion #region 基本方法 public object ExecuteScalar(string cmdText) {  using (SqlConnection conn = new SqlConnection(connString))  {  conn.Open();  SqlCommand cmd = new SqlCommand(cmdText, conn);  return cmd.ExecuteScalar();    } } public DataTable ExecuteDataTable(string cmdText) {  using (SqlConnection conn = new SqlConnection(connString))  {  DataTable dt = new DataTable();  SqlDataAdapter apt = new SqlDataAdapter(cmdText, conn);  apt.Fill(dt);  return dt;  } } public DataTable ExecuteDataTable(string cmdText, int start, int len) {  using (SqlConnection conn = new SqlConnection(connString))  {  DataTable dt = new DataTable();  SqlDataAdapter apt = new SqlDataAdapter(cmdText, conn);  apt.Fill(start, len, dt);  return dt;  } } public string ExecuteNonQuery(string cmdText) {  using (SqlConnection conn = new SqlConnection(connString))  {  conn.Open();  SqlCommand cmd = new SqlCommand(cmdText, conn);  return cmd.ExecuteNonQuery().ToString();  } } #endregion #region 支持查询对象 public DataTable ExecuteDataTable(string sql, SearchCondition cnd, string orderBy) {  string sqlWhere = " where 1=1" + GetUrlFilterSqlWhere(sql) + cnd.getWhereString(false);  sql = string.Format("select {0} from ({1}) sourceTable {2} {3}", cnd.fields, sql, sqlWhere, orderBy);  DataTable dt = this.ExecuteDataTable(sql);  return dt; } public Dictionary<string, object> ExecuteGridData(string sql, QueryBuilder qb) {  string sqlWhere = " where 1=1" + GetUrlFilterSqlWhere(sql) + qb.getWhereString(false);  qb.total = (int)this.ExecuteScalar(string.Format("select count(1) from ({0}) sourceTable {1}", sql, sqlWhere));  sql = string.Format("select {0} from ({1}) sourceTable {2} {3}", qb.fields, sql, sqlWhere, qb.getOrderByString());  DataTable dt = ExecuteDataTable(sql, (qb.page - 1) * qb.rows, qb.rows);  Dictionary<string, object> dic = new Dictionary<string, object>();  dic.Add("total", qb.total);  dic.Add("rows", dt);    return dic; } #endregion #region 私有方法 private string GetUrlFilterSqlWhere(string sql) {  sql = string.Format("select * from({0}) as dt1 where 1=2", sql);  var dtField = ExecuteDataTable(sql);  StringBuilder sb = new StringBuilder();  foreach (string key in HttpContext.Current.Request.QueryString.Keys)  {  if (string.IsNullOrEmpty(key) || key.ToLower() == "id")   continue;  if (dtField.Columns.Contains(key))  {   string value = HttpContext.Current.Server.UrlDecode(HttpContext.Current.Request[key]);   value = value.Replace(",", "','");   sb.AppendFormat(" and {0} in ('{1}')", key, value);  }  }  return sb.ToString(); } #endregion }}

5、用于取代返回值JsonResult的NewtonJsonResult：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Web.Mvc;using System.Web;using System.Data;namespace formula{ public class NewtonJsonResult : JsonResult { public override void ExecuteResult(ControllerContext context) {  //确认是否用于响应HTTP-Get请求  if (this.JsonRequestBehavior == JsonRequestBehavior.DenyGet &&  string.Compare(context.HttpContext.Request.HttpMethod, "GET", true) == 0)  {  throw new InvalidOperationException("禁止Get请求");  }  HttpResponseBase response = context.HttpContext.Response;  //设置媒体类型和编码方式  response.ContentType = string.IsNullOrEmpty(this.ContentType) ?  "application/json" : this.ContentType;  if (this.ContentEncoding != null)  {  response.ContentEncoding = this.ContentEncoding;  }  //序列化对象，并写入当前的HttpResponse  if (null == this.Data) return;  if (this.Data is string)  {  response.Write(Data);  }  else if (this.Data is DataRow)  {  Dictionary<string, object> dic = new Dictionary<string, object>();  DataRow row = this.Data as DataRow;  foreach (DataColumn col in row.Table.Columns)  {   dic.Add(col.ColumnName, row[col]);  }  response.Write(JsonHelper.ToJson(dic));  }  else  {  response.Write(JsonHelper.ToJson(this.Data));  } } }}

6、Json序列化和反序列的帮助类JsonHelper：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using Newtonsoft.Json.Converters;using Newtonsoft.Json;namespace formula{ public static class JsonHelper { public static string ToJson<T>(T obj) {  if (obj == null || obj.ToString() == "null") return null;  if (obj != null && (obj.GetType() == typeof(String) || obj.GetType() == typeof(string)))  {  return obj.ToString();  }  IsoDateTimeConverter dt = new IsoDateTimeConverter();  dt.DateTimeFormat = "yyyy'-'MM'-'dd'T'HH':'mm':'ss";  return JsonConvert.SerializeObject(obj, dt); } /// <summary>  /// 从一个Json串生成对象信息  /// </summary>  /// <param name="jsonString">JSON字符串</param>  /// <typeparam name="T">对象类型</typeparam>   /// <returns></returns>  public static T ToObject<T>(string json) where T : class {  if (String.IsNullOrEmpty(json)) return null;  T obj = JsonConvert.DeserializeObject<T>(json);  return obj; } /// <summary> /// 返回 Diction<string,object> /// </summary> /// <param name="json"></param> /// <returns></returns> public static Dictionary<string, object> ToObject(string json) {  if (String.IsNullOrEmpty(json)) return new Dictionary<string, object>();  return ToObject<Dictionary<string, object>>(json); } /// <summary> /// 返回 List<Dictionary<string, object>> /// </summary> /// <param name="json"></param> /// <returns></returns> public static List<Dictionary<string, object>> ToList(string json) {  if (String.IsNullOrEmpty(json)) return new List<Dictionary<string, object>>();  return ToObject<List<Dictionary<string, object>>>(json); } /// <summary> /// 组装对象 /// </summary> /// <param name="json"></param> /// <param name="obj"></param> public static void PopulateObject(string json, object obj) {  if (String.IsNullOrEmpty(json)) return;  JsonConvert.PopulateObject(json, obj); } }}

7、用于区分系统异常和业务异常的BusinessException：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Runtime.Serialization;namespace formula{ /// <summary> /// 业务异常 /// </summary>  [Serializable] public class BuessinessException : Exception { /// <summary> /// 系统异常构造函数 /// </summary> public BuessinessException() { } /// <summary> /// 系统异常构造函数 /// </summary> /// <param name="message">异常的消息</param> public BuessinessException(string message)  : base(message) { } /// <summary> /// 系统异常构造函数 /// </summary> /// <param name="message">异常的消息</param> /// <param name="inner">内部的异常</param> public BuessinessException(string message, System.Exception inner)  : base(message, inner) { } /// <summary> /// 系统异常构造函数 /// </summary> /// <param name="info">存有有关所引发异常的序列化的对象数据</param> /// <param name="context">包含有关源或目标的上下文信息</param> public BuessinessException(SerializationInfo info, StreamingContext context)  : base(info, context) { } }}
