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
