i have tried this..it works..my problem is that the if a user does not press the escape key first,the first character he presses is NOT displayed in the window..any ideas?

unless you pass true into Console.ReadKey then it is displayed in the console, if you're talking about Console.ReadLine not returning that character then that is current; You'll have to store the character yourselffor later usage

You might try below,

C#

static void ReadUserData()
{
    var info = Console.ReadKey();
    if (info.Key == ConsoleKey.Escape)
    {
        Console.WriteLine("exit");
    }
    else
    {
        Console.WriteLine(string.Format("\nKey has been pressed : {0}", info.Key));
        int n;
        n = Int32.TryParse(Console.ReadLine(), out n) ? n : 0;
        Console.WriteLine(n);
    }
}
