Console use CAPS for user input

问题:

I'm creating a Tic Tac Toe game as a console application using C# (which I am still learning). I want to know if it is possible to change the user input from an x to a capital X because it looks better.

回答1:

You can change a string to its capitalised representation using

.ToUpper();

EDIT - To change it in the console window I'd use this instead:

Console.ReadKey(false)

will hide the pressed key from the console window, then you can write it yourself in capitals.
