Get HTML source code from browser control embedded in C#

Question

I have a browser control embeded in a C# windows app. I want to grab the rendered HTML (which could have been modified by javascript) not the original one.

Any suggestions?

Answer 1

You can get the HTML, and indeed set it, with WebBrowser.DocumentText.

Sheng is correct, DocumentText returns the streamed document before scripts run. His code doesn't compile, but it's essentially correct. I found that you need:

mshtml.HTMLDocument doc = webBrowser1.Document.DomDocument as mshtml.HTMLDocument;
string html = doc.documentElement.outerHTML;

Answer 2

DocumentText internally use the document's IPersistStream interface which returns the original HTML. Use webBrowser1.Document.DocumentElement.OuterHTML instead.
