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.

try handling KeyPress instead of KeyDown.
