Find IP Address In ASP.NET Behind Proxy

Find IP Address Behind Proxy Or Client Machine In ASP.NET, If you want to find the IP address of visitors to your aspx page or application or wanna retrieve IP for other users than u need to write this code

Using this code we can find IP address of visitor even if visitor is behind any proxy

public string IpAddress()
{
string strIpAddress;
strIpAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (strIpAddress == null)
{
strIpAddress = Request.ServerVariables["REMOTE_ADDR"];
}
return strIpAddress;
}

To find IP address of a machine behind LAN you can use this code
string strHostName = System.Net.Dns.GetHostName();
string clientIPAddress = System.Net.Dns.GetHostAddresses
(strHostName).GetValue(1).ToString();

    Hi, I use the Viusal C# Express edition. As far as I know the 2005 version that I am using is based on .Net 2.0, so it should have the System.Management namespace. However, I can't use that namespace... There is no intellisense or anything that popos up after I type it out... Do I need to have a server version of the OS to have System.Management

    Thanks in advance

    To solve the runtime error of Index was outside the bounds of the array use
    string ipaddress = System.Net.Dns.GetHostAddresses(hostname).GetValue(0).ToString();
