asp.net core 获取 MacAddress 地址方法示例

本文告诉大家如何在 dotnet core 获取 Mac 地址

因为在 dotnetcore 是没有直接和硬件相关的，所以无法通过 WMI 的方法获取当前设备的 Mac 地址

但是在 dotnet core 可以使用下面的代码拿到本机所有的网卡地址，包括物理网卡和虚拟网卡

IPGlobalProperties computerProperties = IPGlobalProperties.GetIPGlobalProperties();   NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();   Console.WriteLine("Interface information for {0}.{1}  ",    computerProperties.HostName, computerProperties.DomainName);   if (nics == null || nics.Length < 1)   {    Console.WriteLine(" No network interfaces found.");    return;   }   Console.WriteLine(" Number of interfaces .................... : {0}", nics.Length);   foreach (NetworkInterface adapter in nics)   {    Console.WriteLine();    Console.WriteLine(adapter.Name + "," + adapter.Description);    Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length, '='));    Console.WriteLine(" Interface type .......................... : {0}", adapter.NetworkInterfaceType);    Console.Write(" Physical address ........................ : ");    PhysicalAddress address = adapter.GetPhysicalAddress();    byte[] bytes = address.GetAddressBytes();    for (int i = 0; i < bytes.Length; i++)    {     // Display the physical address in hexadecimal.     Console.Write("{0}", bytes[i].ToString("X2"));     // Insert a hyphen after each byte, unless we are at the end of the      // address.     if (i != bytes.Length - 1)     {      Console.Write("-");     }    }    Console.WriteLine();   }

运行代码，下面是控制台

Interface information for lindexi.github    Number of interfaces .................... : 6    Hyper-V Virtual Ethernet Adapter #4    ===================================    Interface type .......................... : Ethernet    Physical address ........................ : 00-15-5D-96-39-03    Hyper-V Virtual Ethernet Adapter #3    ===================================    Interface type .......................... : Ethernet    Physical address ........................ : 1C-1B-0D-3C-47-91    Software Loopback Interface 1    =============================    Interface type .......................... : Loopback    Physical address ........................ :    Microsoft Teredo Tunneling Adapter    ==================================    Interface type .......................... : Tunnel    Physical address ........................ : 00-00-00-00-00-00-00-E0    Hyper-V Virtual Ethernet Adapter    ================================    Interface type .......................... : Ethernet    Physical address ........................ : 5A-15-31-73-B0-9F    Hyper-V Virtual Ethernet Adapter #2    ===================================    Interface type .......................... : Ethernet    Physical address ........................ : 5A-15-31-08-13-B1

但是可以看到里面有很多不需要使用的网卡，从 堆栈 网找到的方法获取当前有活跃的 ip 的网卡可以通过先判断是不是本地巡回网络等，然后判断有没有网络

foreach (NetworkInterface adapter in nics.Where(c =>    c.NetworkInterfaceType != NetworkInterfaceType.Loopback && c.OperationalStatus == OperationalStatus.Up))

获取当前的网卡有没 ip 有 ip 才是需要的

IPInterfaceProperties properties = adapter.GetIPProperties();    var unicastAddresses = properties.UnicastAddresses;    foreach (var temp in unicastAddresses.Where(temp =>     temp.Address.AddressFamily == AddressFamily.InterNetwork))    {     // 这个才是需要的网卡    }

简单输出网卡使用 adapter.GetPhysicalAddress().ToString() 输出，如果需要输出带连接的请使用 GetAddressBytes 然后自己输出

下面的代码是我抽出来的，可以直接使用

public static void GetActiveMacAddress(string separator = "-")  {   NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();   //Debug.WriteLine("Interface information for {0}.{1}  ",   // computerProperties.HostName, computerProperties.DomainName);   if (nics == null || nics.Length < 1)   {    Debug.WriteLine(" No network interfaces found.");    return;   }   var macAddress = new List<string>();   //Debug.WriteLine(" Number of interfaces .................... : {0}", nics.Length);   foreach (NetworkInterface adapter in nics.Where(c =>    c.NetworkInterfaceType != NetworkInterfaceType.Loopback && c.OperationalStatus == OperationalStatus.Up))   {    //Debug.WriteLine("");    //Debug.WriteLine(adapter.Name + "," + adapter.Description);    //Debug.WriteLine(string.Empty.PadLeft(adapter.Description.Length, '='));    //Debug.WriteLine(" Interface type .......................... : {0}", adapter.NetworkInterfaceType);    //Debug.Write(" Physical address ........................ : ");    //PhysicalAddress address = adapter.GetPhysicalAddress();    //byte[] bytes = address.GetAddressBytes();    //for (int i = 0; i < bytes.Length; i++)    //{    // // Display the physical address in hexadecimal.    // Debug.Write($"{bytes[i]:X2}");    // // Insert a hyphen after each byte, unless we are at the end of the     // // address.    // if (i != bytes.Length - 1)    // {    //  Debug.Write("-");    // }    //}    //Debug.WriteLine("");    //Debug.WriteLine(address.ToString());    IPInterfaceProperties properties = adapter.GetIPProperties();    var unicastAddresses = properties.UnicastAddresses;    if (unicastAddresses.Any(temp => temp.Address.AddressFamily == AddressFamily.InterNetwork))    {     var address = adapter.GetPhysicalAddress();     if (string.IsNullOrEmpty(separator))     {      macAddress.Add(address.ToString());     }     else     {      macAddress.Add(string.Join(separator, address.GetAddressBytes()));     }    }   }  }

上面的方法不仅是在 dotnet core 可以使用，在 dotnet framework 程序同样调用，但是在 dotnet framework 还可以通过 WMI 获取

在 dotnet framework 使用 WMI 获取 MAC 地址方法

var managementClass = new ManagementClass("Win32_NetworkAdapterConfiguration");     var managementObjectCollection = managementClass.GetInstances();     foreach (var managementObject in managementObjectCollection.OfType<ManagementObject>())     {      using (managementObject)      {       if ((bool) managementObject["IPEnabled"])       {        if (managementObject["MacAddress"] == null)        {         return string.Empty;        }        return managementObject["MacAddress"].ToString().ToUpper();       }      }     }

输出的格式是 5A:15:31:73:B0:9F 同时输出是一个网卡
