How to prevent a key from being held down on a button? C#

I am writing a game where you need to click a button as m开发者_StackOverflow中文版any times as you can in 10 seconds. The problem is that it is possible to hold the Enter key down to superspeed the counter.

How can I prevent this? I tried KeyDown Events but it doesn't seem to fire when the key is held down.

Thanks.

Use the MouseClick event as that only captures clicks by the mouse.
