C# WebBrowser Url Control

Question

Hi.

when I navigate this site:

http://bp.olispace.ca/wiki

it is going to: http://bp.olispace.ca/wiki/index.php?title=Main_Page . page

I want to go to http://bp.olispace.ca/wiki/index.php?title=Special:UserLogin&type=signup&returnto=Main_Page register page when I click button1 in my web based application.

how can I add "title=Special:UserLogin&type=signup&returnto=Main_Page" query to webBrowser1 url instead of "title=Main_Page" query when webBrowser on the http://bp.olispace.ca/wiki/index.php?title=Main_Page page.

I think my problem is simple. (go to register page on a wiki site by clicking button1). but I can't solve this problem.

What code should I write in button1 click event

Thanks
