Waiting for a Mouse Click

Hi all;
I am writing a small application. This application has a Botton. When I push the bottom, I need to let the program wait for a MOUSE CLICK. And after the mouse click, the application can continue the the next process. Is there any possibility in C#, to let the program wait for a mouse click?
Thanks

By pushing the button, don't you mean 'click' the button?

Take a look at the MouseClick or MouseDown event
