推荐答案

protected void Page_Load(object sender, EventArgs e)
       {
          string macid= GetMacAddress("pass IP Address of the mechine");
       }
       [DllImport("iphlpapi.dll", ExactSpelling = true)]
       public static extern int SendARP(int DestIP, int SrcIP, [Out] byte[] pMacAddr, ref int PhyAddrLen);
       public string GetMacAddress(string sName)
       {
           string s = string.Empty;
           System.Net.IPHostEntry Tempaddr = null;
           Tempaddr = (System.Net.IPHostEntry)Dns.GetHostEntry(sName);
           System.Net.IPAddress[] TempAd = Tempaddr.AddressList;
           string[] Ipaddr = new string[3];
           foreach (IPAddress TempA in TempAd)
           {
               Ipaddr[1] = TempA.ToString();
               byte[] ab = new byte[6];
               int len = ab.Length;
               int r = SendARP((int)TempA.Address, 0, ab, ref len);
               string sMAC = BitConverter.ToString(ab, 0, 6);
               Ipaddr[2] = sMAC;
               s = sMAC;
           }
           return s;
       }

namespace: using System.Management;
string id=" ";
ManagementObjectSearcher query = null;
ManagementObjectCollection queryCollection = null;

      try
      {
               query = new ManagementObjectSearcher("SELECT * FROM                                  Win32_NetworkAdapterConfiguration");
            queryCollection = query.Get();
            foreach (ManagementObject mo in queryCollection)
            {
              if (mo["MacAddress"] != null)
              {
                 id = mo["MacAddress"].ToString();
                 MessageBox.Show(id);
              }
            }
      }
      catch (Exception ex)
      {
            MessageBox.Show(ex.Source);
            MessageBox.Show(ex.Message);
      }

GetMacAdress方法，不使用System.Management

GetMacAdress method without using System.Management

private string GetMAC()
        {
            string macAddresses = "";

            foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
            {
                if (nic.OperationalStatus == OperationalStatus.Up)
                {
                    macAddresses += nic.GetPhysicalAddress().ToString();
                    break;
                }
            }
            return macAddresses;
        }
