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");
}

}

Get the Unique keyboard values and detect it. Each key has an ASCII.
