Simple c# question

I'm kind of new to programming, how does one read a single button press from the keyboard, and then check to make sure that it's a printable character?

Also, how does one take a integer input from the keyboard? More specifically, how do I force the user to retry their input until it's a number I accept?

You both sound foolish as hell. Asking others who know more has been and will remain for a long time the easiest way to learn. Poster 4? Why so angry? Calm down, you'll get sweaty, and everyone knows you smell like ass when you sweat.
