      asp.net core 获取 MacAddress 地址方法示例

       更新时间£º2019年02月18日 09:34:24   作者£ºlindexi   我要评论

      这篇文章主要介绍了asp.net core获取MacAddress地址方法£¬小编觉得挺不错的£¬现在分享给大家£¬也给大家做个参考¡£一起跟随小编过来看看吧

      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?#21543;?#22791;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?#19981;?#32593;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?#39029;?#20986;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
