c#中獲取服務器IP，客戶端IP以及網卡物理地址

 客戶端ip:
 Request.ServerVariables.Get("Remote_Addr").ToString();
 客戶端主機名:
 Request.ServerVariables.Get("Remote_Host").ToString();
 客戶端浏覽器IE：
 Request.Browser.Browser;
 客戶端浏覽器 版本號：
 Request.Browser.MajorVersion;
 客戶端操作系統：
 Request.Browser.Platform;
 服務器ip:
 Request.ServerVariables.Get("Local_Addr").ToString();
 服務器名：
 Request.ServerVariables.Get("Server_Name").ToString();
 如果你想進一步了解ServerVariables，可以用
 foreach(String o in Request.ServerVariables){
 Response.Write(o+"="+Request.ServerVariables[o]+"<br>");
 }
 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(); //獲取網卡的地址
        string[] IPAddresses = (string[]) MO["IPAddress"]; //獲取本地的IP地址
        if(IPAddresses.Length > 0)
        stringIP = IPAddresses[0];
        Response.Write(stringMAC+"/"+stringIP);
      }
    }
 asp.net+c#如何獲取客戶端網卡的MAC地址？

 //在頁面上打印出客戶端的網卡物理地址（MAC）
 Response.Write(this.GetMac(Request.UserHostAddress.ToString()));
