WebRequest using WebBrowser cookie C#

[dschu012]

I am logging into a site using a WebBrowser. Once I log in I want to save an Image from within it without having to make the WebBrowser navigate to the URL where the Image is stored. Currently I am doing this

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(myUri);
request.Headers.Add(HttpRequestHeader.Cookie, webBrowser1.Document.Cookie);
WebResponse response = request.GetResponse();
Image captchaImage = Image.FromStream(response.GetResponseStream());
 

The Image is different whether you are logged in or not and the Image I get from the above code is the Image one would get if you are not logged in. Would I need to do more than just set the Cookie to the Cookie of the WebBrowser?

You need to supply credentials which will authenticate your user with the website.

If the website uses Windows Authentication to authenticate the user, you need to supply a NetworkCredential to the WebRequest. You supply the NetworkCredential to the WebRequest's Credentials property.

If the website uses Forms authentication, this process is a lot harder to implement.
