How to get document.documentMode property from WebBrowser control

I have a very simple forms application with WebBrowser control on the form which I want to use to debug rendering issues, especially which documentType is used by the browser. When I navigate in IE to the website, it's easy - I open up the JS console and type document.documentType and get value.

How can I achieve the same from the C# and WebBrowser control?

I have tried:

private void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e)
{
    if (webBrowser1.Document != null)
    {
        var document = webBrowser1.Document;
        mshtml.IHTMLDocument doc = (mshtml.IHTMLDocument) document.DomDocument;   
    }
}

But the doc doesn't seem to surface documentMode property easily.

You can cast the Document.DomDocument to dynamic and get the document mode using documentMode property:

var documentMode = ((dynamic)(webBrowser1.Document.DomDocument)).documentMode;

Just make sure you are using the code in DocumentCompleted event of WebBrowser.
