title: Numpad key codes in C#
body: <p>I use these following codes to work with numpad keys. </p>
  
  <pre><code>if (e.KeyCode == Keys.NumPad0 || e.KeyCode == Keys.D0)
  {
     MessageBox.Show("You have pressed numpad0");
  }
  if (e.KeyCode == Keys.NumPad1 || e.KeyCode == Keys.D1)
  {
     MessageBox.Show("You have pressed numpad1");
  }
  </code></pre>
