C#: How to invoke a click in a httpwebrequest?

问题

I want to invoke the click on a page where you fill data too. I tried doing it with two httpwebrequests where one is for the page and one is where it transfers the session information and makes an account on the site which is the goal of my program.

Everytime I tried to do it with two webrequests a certain field wasnt filled in but when I did it with one everything was filled out.

So basically is it possible to invoke a click on a page with one httpwebrequest?
