C# - Console Keystrokes

try this:

ConsoleKeyInfo keypress;
keypress = Console.ReadKey(); // read keystrokes 

if (keypress.Key == ConsoleKey.LeftArrow)
{
    Console.BackgroundColor = ConsoleColor.Cyan;
}

You need to use keypress.Key (instead of .KeyChar) - also your "Cyan" should be ConsoleColors.Cyan too.

Try this:

    ConsoleKeyInfo keypress;
    keypress = Console.ReadKey(); // read keystrokes 
    if ( (int)keypress.Key == (char)ConsoleKey.LeftArrow )
    {
        Console.BackgroundColor = ConsoleColor.Cyan;
    }
