The Keyboard class also provides information about the state of the keys on the keyboard. For instance, the IsKeyDown method returns whether a specified key is down.

The following example checks whether the key associated with an instance of KeyEventArgs is down by obtaining the state of the IsDown property.

// e is an instance of KeyEventArgs.
// btnIsDown is a Button.
if (e.IsDown)
    btnIsDown.Background = Brushes.Red;
