Instead of using Console.ReadLine you are going to have to use Console.ReadKey. Something along the lines of this:-

C#
string str = string.Empty;
               while (str.Length <= 5)
               {
                   char c = Console.ReadKey(true).KeyChar;
                   if (c == '\r')
                   {
                       //user pressed enter
                       break;
                   }
                   if (c == '\b')
                   {
                       //User pressed backspace
                       if (str != string.Empty)
                       {
                           str = str.Substring(0, str.Length - 1);
                           Console.Write("\b \b");
                       }
                   }
                   int enteredValue;
                   if(Int32.TryParse(c.ToString(), out enteredValue))
                   {
                       Console.Write(c);
                       str += c;
                   }
               }
               Console.WriteLine();
               Console.WriteLine("You entered " + str);
               Console.ReadLine();


This checks if the char entered is numeric, it handles backspaces and it checks to see if the user pressed enter. I am sure you could alter this to work with your app.

Hope it helps
