Method 1

    String clientIP = 
(HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]==null)?
HttpContext.Current.Request.UserHostAddress:
HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

Method 2

HttpContext.Current.Request.UserHostAddress

This doesn’t attempt to take into account proxies. For that, you can use Request.ServerVariables["HTTP_X_FORWARDED_FOR"]. However, make sure you’re not trusting that blindly, since it could be forged. It’s better to keep a whitelist of IPs for which you trust it.
