Get HTTP for a site which also has Javascript on it in C#

Question

I need to get the HTML of a website which is heavy on Javascript. When I try to do I get a receive code, but it is filled with Javascript.

Can I execute that JS after downloading and get the resulting HTML out of it?

So you're trying to capture the response from an HTTP request to a website? And did you mean "exclude the JavaScript", rather than "execute"? — Tieson T.

The problem is, when I try to do the GET to aham...get..the website..it comes back with a lot of javascript code. I would like to execute that code, not exclude it. By executing it I would get the HTTP I want. — Daniel

Most JavaScript don't output HTML but are responsible for other things, such as AJAX, animations etc. — RvdK

@Daniel As @Al W alludes to below, you need something the evaluate the JavaScript, which normally means a web browser. The WinForms libraries contain a WebBrowser control you can use (which you can create purely in code, if memory serves me right) rather than sending it to an external browser application. — Tieson T.

The most straight forward way to do this would be to embed a WebBrowser control into a windows form and then use the DOM
