Try the bellow code // An keypress event example. using System; // Derive a custom EventArgs class that holds the key. class KeyEventArgs : EventArgs { public char ch; } // Declare a delegate for an event. delegate void KeyHandler ( object source, KeyEventArgs arg ) ; // Declare a key-press event class. class KeyEvent { public event KeyHandler KeyPress; // This is called when a key is pressed. public void OnKeyPress ( char key ) { KeyEventArgs k = new KeyEventArgs () ; if ( KeyPress != null ) { k.ch = key; KeyPress ( this, k ) ; } } } // A class that receives key-press notifications. class ProcessKey { public void keyhandler ( object source, KeyEventArgs arg ) { Console.WriteLine ( "Received keystroke: " + arg.ch ) ; } } // Another class that receives key-press notifications. class CountKeys { public int count = 0 ; public void keyhandler ( object source, KeyEventArgs arg ) { count++; } } // Demonstrate KeyEvent. public class KeyEventDemo { public static void Main () { KeyEvent kevt = new KeyEvent () ; ProcessKey pk = new ProcessKey () ; CountKeys ck = new CountKeys () ; char ch; kevt.KeyPress += new KeyHandler ( pk.keyhandler ) ; kevt.KeyPress += new KeyHandler ( ck.keyhandler ) ; Console.WriteLine ( "Enter some characters. " + "Enter a period to stop." ) ; do { ch = ( char ) Console.Read () ; kevt.OnKeyPress ( ch ) ; } while ( ch != '.' ) ; Console.WriteLine ( ck.count + " keys pressed." ) ; } }

Use Console.ReadLine method to let the user input, and the return value is the user's input. Let me know if I don't understand you right.
