Retrieve webpage with HttpWebRequest

Question

Hi all, I am coding something like a webspider. So, giving an valid uri, I must receive an html page of the related uri. but when the related page is built into frames It not run cuz I cannot dump frames contents. Some one can tell me if there are some .Net objects or class that can permit to dump a webpage(with the frames contents as it is viewable on browser)? Thanx a lot TT
