Why does HtmlElement's GetAttribute() method return "mshtml.HTMLInputElementClass" instead of the attribute's value?

Question

Why does HtmlElement's GetAttribute() method return mshtml.HTMLInputElementClass instead of the attribute's value, when I'm trying to obtain the value of a form's action attribute?

HtmlElementCollection elements = webBrowser1.Document.Forms;
   foreach (HtmlElement element in elements)
        MessageBox.Show(element.GetAttribute("action") + "");

Answer 1

It seems to be an IE bug.

Here is a solution : add a reference to Microsoft.mshtml, then :

if(element.GetAttribute("action").Equals("mshtml.HTMLInputElementClass"))
{
    mshtml.IHTMLFormElement iForm = (mshtml.IHTMLFormElement)element.DomElement; 
    string action = iForm.action;
}

Hope this help :)
