Block user from entering letters

Question

I have a menu that switch the options by pressing the UpArrow and the DownArrow, i want to prevent the user from entering letters or numbers or any key that print something on the screen.

I was thinking to set the cursor position at the end of the text and than print a white space but it prints the letter after the white space, maybe if there's an event that occurs after the letter is printed on screen.

Any ideas?

So you only want to allow the up and down arrow and Enter, is that correct? — Rufus L, Nov 08 '17 at 01:19

You can use Console.ReadKey(intercept: true) to get a key without echoing it to the console.
