How to close parent form from child form in Windows Forms 2.0?

Question

I need to close the parent form from a child form from a Windows application. What would be the best way to do this?

Answer 1

When you close a form in WinForms, it distributes all its children. So this is not a good idea. You must do this asynchronously, for example, you can send a message to the parent form.

Answer 2

I looked at this blog post, which looks like it will work, and uses the concept of the event handler from the D2VIANT answer
