httpwebrequest

I'm trying to set the HttpRequestHeader for a HttpWebRequest like so:

new HttpWebRequest().Headers.Add(HttpRequestHeader.UserAgent, "Mozilla/4.0");

But I get an exception: System.ArgumentException: This header must be modified using the appropriate property.

How should I be setting the header?
