You can't do this sort of thing in .NET because in .NET everything must be strongly typed. So dynamically accessing properties is not really possible.

There are two ways to work around this:

Using Reflection to access properties/methods dynamically
Import the appropriate object model COM objects

The first requires explicit access to each of the object using the Type object and its various reflection properties like GetField()/GetProperty() etc. to set and retreieve values and call methods. This is a lot of work.

The other alternative is to import MSHTML.DLL as a COM reference or use the Microsoft.mshtml which is ONLY available with VS.NET - if you do make sure to Copy local on that assembly. Either way the assembly for MSHTML will be over 2 megs because the object model is huge.

Once you've done this though you can easily access the Web Browser control with full intellisense:

mshtml.HtmlDocument doc = (mshtml.HtmlDocument) this.Browser.Document
string Body = doc.body.innerHtml;
object Item = doc.getElementByID("txtTextBox");

The main thing is that you have to type everything explicitly, so in the case of GetElementById you'd have to cast to the proper Input object and so on.


Although it looks like more work it's actually much nicer because you get the support of strong typing plus the ability to have Intellisense help you through the entiry hierarchy.

The only major downer is the need to distribute hte 2 meg Interop assebmly.
