Full HTML page downloader

Hi developers. I need C# code for downloading full html page (including css, javascript and images) to local file system. Only one page, not full web, no support for downloading video streams. Internal links to components of the page (images, css, javascript) should be modified so that the page can be displayed later from this local copy without connection to internet. I prefer solution using HTMLAgilityPack. I know that not all pages can be downloaded so simply, no problem, I do not need support for special techniques like data streams, ajax, etc. The class should look like this: public class HtmlPageDownloader{ public void DownloadPage(String url, String localPath, String localMainFileName){ ... } } Usage: DownloadPage("[login to view URL]", "c:\\DownloadedPages\Page1", "[login to view URL]");
