GeckoFX DocumentText Similar To Webbrowser Control (C#)

In a traditional webbrowser control, you can get the page source like this:

string pageSource = webbrowser1.DocumentText;

However, in GeckoFX webbrowser, there's no DocumentText property. A workaround is to get the InnerHtml property of html tag using the code below:

string pageSource = string.empty;   
 if (!string.IsNullOrEmpty(this.Document.GetElementsByTagName("html")[0].InnerHtml))  
     pageSource = this.Document.GetElementsByTagName("html")[0].InnerHtml;

Cheers!
