You'll want to run a test to make sure that it was a ProtocolError:

if (e.Status == WebExceptionStatus.ProtocolError) 
{
    Console.WriteLine("Status Code : {0}", ((HttpWebResponse)e.Response).StatusCode);
    Console.WriteLine("Status Description : {0}", ((HttpWebResponse)e.Response).StatusDescription);
}

You could try to parse the message, but there isn't always an error number. A timeout for example doesn't result in an HTTP error code.
