HtmlAgilityPack: Get whole HTML document as string

Does HtmlAgilityPack have the ability to return the whole HTML markup from an HtmlDocument object as a string?

Sure, you can do like this:

HtmlDocument doc = new HtmlDocument();
// call one of the doc.LoadXXX() functions
Console.WriteLine(doc.DocumentNode.OuterHtml);

OuterHtml contains the whole html.

You can create WebRequest passing Url and Get webResponse . Get ResponseStream from WebResponse and read it into a String.

string result = string.Empty;

WebRequest req = WebRequest.Create(Url);
WebResponse res= wrq.GetResponse();    
StreamReader reader = new StreamReader(res.GetResponseStream());
result = reader.ReadToEnd();    
reader.Close();
res.Close();

Hope this helps.
