How to open IE with post info in C#?

Question

I am developing a small program which as a windows form. On this form, I want to put a link, and when user click the link, a seperate IE browser will be open with post data.

Answer 1

You can just start process by sending URL in Process.Start as parameter. There is a problem while calling StartProcess from WebForms GUI thread because of synchronization context. My solution uses thread pool for this purpose. Advantage of this solution is that an URL is opened in user preferred web browser that can be IE, Firefox etc.
