RE: Unable to cast COM object of type 'System.__ComObject' to class type 'mshtml.HTMLDocumentClass'

Hello,
Below is my existing code...
mshtml.IHTMLDocument3 doc = (mshtml.IHTMLDocument3)axWebBrowser1.Document;
string strHtml = ((mshtml.HTMLDocumentClass) (doc)).documentElement.outerHTML +
Environment.NewLine;

But I am getting error as......
Unable to cast COM object of type 'System.__ComObject' to class type 'mshtml.HTMLDocumentClass'. COM components that enter the CLR and do not support IProvideClassInfo or that do not have any interop assembly registered will be wrapped in the __ComObject type. Instances of this type cannot be cast to any other class; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface.

Please Help,
