ASP.NET获取IP与MAC

获取服务器的IP地址方法以DNS法较为简单实用，如下：
  using System.Net;

 

 private void ButtonIP_Click(object sender, System.EventArgs e)
  { 
     System.Net.IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;
     if ( addressList.Length>1)
     {   TextLIP.Text = addressList[0].ToString();
          TextSIP.Text = addressList[1].ToString();
     }
     else
     {
          TextLIP.Text = addressList[0].ToString();
          TextSIP.Text = "没有可用的连接";
     }
  }

获取服务器的IP地址与MAC地址另一方法如下：

   using System.Management;

 

   string stringMAC = "";
   string stringIP = "";
   ManagementClass MC = new ManagementClass "Win32_NetworkAdapterConfiguration");
   ManagementObjectCollection MOC= MC.GetInstances();
  
   foreach(ManagementObject MO in MOC)
   {
    if ((bool)MO["IPEnabled"] == true)
    {
     stringMAC += MO["MACAddress"].ToString();
     TextMAC.Text = stringMAC.ToString();
     string[] IPAddresses = (string[]) MO["IPAddress"];
     if(IPAddresses.Length > 0)
     stringIP = IPAddresses[0];
     TextIP.Text = stringIP.ToString();
    }
   }
