C#获取客户端ip

客户端ip:
Request.ServerVariables.Get("Remote_Addr").ToString();
客户端主机名:
Request.ServerVariables.Get("Remote_Host").ToString();
客户端浏览器IE：
Request.Browser.Browser;
客户端浏览器 版本号：
Request.Browser.MajorVersion;
客户端操作系统：
Request.Browser.Platform;
服务器ip:
Request.ServerVariables.Get("Local_Addr").ToString();
服务器名：
Request.ServerVariables.Get("Server_Name").ToString();
如果你想进一步了解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(); //获取网卡的地址
       string[] IPAddresses = (string[]) MO["IPAddress"]; //获取本地的IP地址
       if(IPAddresses.Length > 0)
       stringIP = IPAddresses[0];
       Response.Write(stringMAC+"/"+stringIP);
     }
   }
