Using below code you can fetch User's system IP-Address.

The Problem

Sometime you want to fetch user's IP-Address for monitoring purpose. You can easily get it from current HTTP request. Let's see how to do this.

A quick solution

Simply put this code in your code. Below example useHttpContext.Current.Request to get Current HTTP request.

You can find HttpContext.Current.Request in System.Web namespace.

Code

    public class Utility
    {
        public string GetSystemIPAddress()
        {
            return HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] ?? HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
        }

    }

Implementation

Let's call this method.

    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("System IP-Address is:" + new Utility().GetSystemIPAddress());
        }
    }

Hope this can help you.
