c# - Read X-Forwarded-For header

I want to read the value of the X-Forwarded-For header value in a request.

I've tried

HttpContext.Current.Request.Headers["X-Forwarded-For"].Split(new char[] { ',' }).FirstOrDefault();  

in C#.

OR do I need to split the header by ":" and the take the second string? I am asking this because, Wikipedia says

The general format of the field is: X-Forwarded-For: client1, proxy1, proxy2

See Question&Answers more detail:os

The format that you get in return is client1, proxy1, proxy2

So you split it with the comma, and get the first to see the ip of your client.
