Set user agent header with webrequest

[Jon Spivey]

Hi,

I'm using webrequest to scrape some urls, works fine, however one url seems
to be throwing an error when it doesn't recognise the user agent. So I need
to set the user agent to something like MSIE, I've tried these
WebRequest.Headers.Set("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0;
Windows NT 5.1")
WebRequest.Headers.Add("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0;
Windows NT 5.1")
WebRequest.Headers.Item("User-Agent") = "Mozilla/4.0 (compatible; MSIE 6.0;
Windows NT 5.1; )")
and they all give the same error "System.ArgumentException: This header must
be modified with the appropriate property"

What's the correct way to set the User Agent header?

Cheers,
Jon

Trick question? HttpWebRequest.UserAgent

There's no WebRequest.UserAgent property, but there is a HttpWebRequest.UserAgent property. You can use:

((HttpWebRequest)request).UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)";
