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?
UserAgent
is a property. So set it like this:
HttpWebRequest request = new HttpWebRequest();
request.UserAgent = "Mozilla/4.0";
