终于开始做用户部分了，先做注册
一用户 
1.1用户注册 
首先在Models里添加用户注册模型类UserRegister 继承自User，在类中new一下密码字段，并添加重复密码和验证码字段。完成后的代码 

/// <summary> /// 用户注册模型 /// </summary> public class UserRegister : User { /// <summary> /// 密码 /// </summary> [Display(Name="密码",Description="6-20个字符。")] [Required(ErrorMessage = "×")] [StringLength(20,MinimumLength=6,ErrorMessage = "×")] [DataType(DataType.Password)] public new string Password { get; set; } /// <summary> /// 确认密码 /// </summary> [Display(Name = "确认密码", Description = "再次输入密码。")] [Compare("Password", ErrorMessage = "×")] [DataType(DataType.Password)] public string RePassword { get; set; } /// <summary> /// 验证码 /// </summary> [Display(Name = "验证码", Description = "请输入图片中的验证码。")] [Required(ErrorMessage = "×")] [StringLength(6,MinimumLength=6,ErrorMessage = "×")] public string VerificationCode { get; set; } }

打开Controllers，在public ActionResult Register()上点右键添加视图，选强类型视图，模型类选择UserRegister 

添加完成后转到Register.cshtml编辑视图，删除掉自动生成的内容，手动输入想要的代码，完成后代码如下： 

@model CMS.Models.UserRegister@{ ViewBag.Title = "用户注册"; Layout = "~/Views/Shared/_Layout.cshtml";}<div class="banner"> <img src="https:/article/~/Skins/Default/Images/banner.jpg" /></div>@using (Html.BeginForm()){ @Html.ValidationSummary(true) <div class="form"> <dl>  <dt>用户注册</dt>  <dd>  <div class="label">@Html.LabelFor(model => model.UserName)：</div>  <div class="ctrl">@Html.EditorFor(model => model.UserName)   @Html.ValidationMessageFor(model => model.UserName)   @Html.DisplayDescriptionFor(model => model.UserName)  </div>  </dd>  <dd>  <div class="label">@Html.LabelFor(model => model.Gender)：</div>  <div class="ctrl">@Html.RadioButton("Gender", 0) 男 @Html.RadioButton("Gender", 1) 女 @Html.RadioButton("Gender", 2, true) 保密   @Html.ValidationMessageFor(model => model)   @Html.DisplayDescriptionFor(model => model)  </div>  </dd>  <dd>  <div class="label">@Html.LabelFor(model => model.Password)：</div>  <div class="ctrl">@Html.PasswordFor(model => model.Password)   @Html.ValidationMessageFor(model => model.Password)   @Html.DisplayDescriptionFor(model => model.Password)  </div>  </dd>  <dd>  <div class="label">@Html.LabelFor(model => model.RePassword)：</div>  <div class="ctrl">@Html.PasswordFor(model => model.RePassword)   @Html.ValidationMessageFor(model => model.RePassword)   @Html.DisplayDescriptionFor(model => model.RePassword)  </div>  </dd>  <dd>  <div class="label">@Html.LabelFor(model => model.SecurityQuestion)：</div>  <div class="ctrl">@Html.EditorFor(model => model.SecurityQuestion)   @Html.ValidationMessageFor(model => model.SecurityQuestion)   @Html.DisplayDescriptionFor(model => model.SecurityQuestion)  </div>  </dd>  <dd>  <div class="label">@Html.LabelFor(model => model.SecurityAnswer)：</div>  <div class="ctrl">@Html.EditorFor(model => model.SecurityAnswer)   @Html.ValidationMessageFor(model => model.SecurityAnswer)   @Html.DisplayDescriptionFor(model => model.SecurityAnswer)  </div>  </dd>  <dd>  <div class="label">@Html.LabelFor(model => model.Email)：</div>  <div class="ctrl">@Html.EditorFor(model => model.Email)   @Html.ValidationMessageFor(model => model.Email)   @Html.DisplayDescriptionFor(model => model.Email)  </div>  </dd>  <dd>  <div class="label">验证码：</div>  <div class="ctrl">   @Html.TextBoxFor(model => model.VerificationCode)   @Html.ValidationMessageFor(model => model.VerificationCode)   <img id="verificationcode" alt="" src="https:/article/@Url.Action("VerificationCode", "User")" />   <a id="trydifferent" style="cursor:pointer">换一张</a>  </div>  </dd>  <dd>  <div class="label">注册条款：</div>  <div class="ctrl">   @Html.CheckBox("Agreement",new {@class="required"})   我已阅读并同意注册条款  </div>  </dd>  <dd>  <div class="label"></div>  <div class="ctrl">   <input type="submit" value="注册" />  </div>  </dd> </dl> <div class="clear"></div> </div>}<script type="text/javascript" > $("#trydifferent").click(function () { $("#verificationcode").attr("src", "/User/VerificationCode?"+new Date()); }) </script>@section Scripts { @Scripts.Render("~/bundles/jqueryval")}

下面开始写注册处理的代码。 
在Controllers，在public ActionResult Register(){return View();}下面添加一个[HttpPost]方式的Register() Action，代码如下： 

[HttpPost] public ActionResult Register(UserRegister userReg) {  if (Session["VerificationCode"] == null || Session["VerificationCode"].ToString() == "")  {  Error _e = new Error { Title = "验证码不存在", Details = "在用户注册时，服务器端的验证码为空，或向服务器提交的验证码为空", Cause = "<li>你注册时在注册页面停留的时间过久页已经超时</li><li>您绕开客户端验证向服务器提交数据</li>", Solution = "返回<a href='https:/article/" + Url.Action("Register", "User") + "'>注册</a>页面，刷新后重新注册" };  return RedirectToAction("Error", "Prompt", _e);  }  else if (Session["VerificationCode"].ToString() != userReg.VerificationCode.ToUpper())  {  ModelState.AddModelError("VerificationCode", "×");  return View();  }  userRsy = new UserRepository();  if (userRsy.Exists(userReg.UserName))  {  ModelState.AddModelError("UserName", "用户名已存在");  return View();  }  User _user = userReg;  _user.Password = Common.Text.Sha256(userReg.Password);  _user.RegTime = System.DateTime.Now;  if (userRsy.Add(_user))  {  Notice _n = new Notice { Title = "注册成功", Details = "您已经成功注册，用户为：" + _user.UserName + " ，请牢记您的密码！", DwellTime = 5, Navigation = Url.Action("Login", "User") };  return RedirectToAction("Notice", "Prompt", _n);  }  else  {  Error _e = new Error { Title = "注册失败", Details = "在用户注册时，发生了未知错误", Cause = "系统错误", Solution = "<li>返回<a href='https:/article/" + Url.Action("Register", "User") + "'>注册</a>页面，输入正确的信息后重新注册</li><li>联系网站管理员</li>" };  return RedirectToAction("Error", "Prompt", _e);  } }

OK，运行一下看看效果 

输入完数据点注册。OK 看到注册成功的页面了

看一下数据库中也有相应记录了

注册功能就完成了。
