public static string GetIPAddress(NameValueCollection serverVariables)
{
var ip = serverVariables["HTTP_X_FORWARDED_FOR"];
if (!string.IsNullOrEmpty(ip))
{
string[] ipRange = ip.Split(',');
if (null != ipRange && ipRange.Length > 0)
{
int le = ipRange.Length - 1;
string trueIP = ipRange[le];
ip = trueIP;
}
else
{

else
{
ip = serverVariables["REMOTE_ADDR"];

return ip;
}
Ex: string userIPAddress = GetIPAddress(Request.ServerVariables);
