System.Windows.Forms.HtmlElement is a wrapper for the Internet Explorer Document Object Model (DOM), which is written using the Component Object Model (COM). If you need to access unexposed properties or methods on the underlying COM interfaces, such as IHTMLElement, you can use this object to query for them.

In order to use the unmanaged interfaces, you will need to import the MSHTML library (mshtml.dll) into your application. However, you can also execute unexposed properties and methods using the Invoke method.
