How to get HTML from WebBrowser control

Question

There are loads of posts similar to this.

How to get rendered html (processed by Javascript) in WebBrowser control? suggests to use something like

webBrowser1.Document.GetElementsByTagName("HTML")[0].OuterHtml;

Document is treated as an object, I have no option to use GetElementsByTagName

Copy all text from webbrowser control suggests to use DocumentText

I have Document but no DocumentText

That post also suggests webBrowser.Document.Body.InnerText;

I have the option to use webBrowser.Document but that is it. For some reason webBrowser.Document is an object and as such I can't access these methods.

Getting the HTML source through the WebBrowser control in C# also suggests using DocumentStream. Again, I don't have that.

I'm doing this in a WPF application and using WebBrowser from System.Windows.Controls

All I'm trying to is read the rendered HTML from the web page.

My code

public void Begin(WebBrowser wb)
{
   this._wb = wb;
   _wb.Navigated += _wb_Navigated;
   _wb.Navigate("myUrl");
}

private void _wb_Navigated(object sender, System.Windows.Navigation.NavigationEventArgs e)
{
    var html = _wb.Document;//this is where I need help
}

Your samples refer to the WinForms-WebBrowserControl. Add a reference to Microsoft.mshtml (via add-reference dialog->search) to your project.

Cast the Document-Property to

HTMLDocument

in order to access methods and properties (as stated on MSDN).

See also my GitHub-Sample:

private void WebBrowser_Navigated(object sender, NavigationEventArgs e) {
    var document = (HTMLDocument)_Browser.Document;
     _Html.Text = document.body.outerHTML;
}
