In Console Application using System; namespace ConsoleApplication1 { class Program { static void Main( string [] args) { ConsoleKeyInfo consoleKeyInfo = Console.ReadKey(); if (consoleKeyInfo.Key == ConsoleKey.Enter) { Console.WriteLine( "You have Pressed Enter Key" ); } if (consoleKeyInfo.Key == ConsoleKey.Escape) { Console.WriteLine( "You have Pressed Escape Key" ); } } } } In Windows Form Application You can fire keydown event of your control suppose I want to close from on Escape and Want to show Alert Message on Enter then I will do like as follows private void Form_KeyDown( object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Escape) { MessageBox.Show( "Hello You have pressed Escape" ) this .Close(); } if (e.KeyCode == Keys.Enter) { MessageBox.Show( "Hello You have pressed Enter" ) } }

hi, for this you can create keyDown event and check for the keys which is pressed for in your ex, private void txtbox1_KeyDown( object sender, KeyEventArgs e) { if (e.Key == Key.Enter) //enter { System.Windows.Forms.MessageBox.Show( "enter" ); } if (e.Key == Key.Return) //enter { System.Windows.Forms.MessageBox.Show( "enter" ); } if (e.Key == Key.Escape) //escape { System.Windows.Forms.MessageBox.Show( "escape" ); } }
