C# - passing authentication credentials with HttpWebRequest

Question

I am working on a tool that parses html source of given urls. Some of them are password protected.

Here is my question: How can I pass authentication credentials with the HttpWebRequest? Does it require setting up a cookie? These are new grounds to me, thus examples would be very helpful.

In summary, I use the following for requests that not require an authentication.

...
HttpWebRequest request =(HttpWebRequest)WebRequest.Create(HttpUtility.UrlDecode(<URL   STRING>));
...
HttpWebResponse response =(HttpWebResponse)request.GetResponse();

Solution 1

For Basic authentication (not sure about other authentication schemes):

request.Credentials = new NetworkCredential("username", "password");

Solution 2

For forms authentication where a valid cookie is available in the page Context, you can use this answer.

The same works well for Integrated Windows authentication scheme as well if you have domain credentials of a specific user.
