还有一点:
private void button1_Click ( object sender, EventArgs e )
{
if( (ModifierKeys & Keys.Control) == Keys.Control )
{
ControlClickMethod();
}
else
{
ClickMethod();
}
}
private void ControlClickMethod()
{
MessageBox.Show( "Control is pressed" );
}
private void ClickMethod()
{
MessageBox.Show ( "Control is not pressed" );
}

假设WinForms,请使用Control.ModifierKeys,例如:
private void button1_Click(object sender, EventArgs e) {
MessageBox.Show(Control.ModifierKeys.ToString());
}
假设使用WPF,请使用Keyboard.Modifiers,例如:
private void Button_Click(object sender, RoutedEventArgs e) {
MessageBox.Show(Keyboard.Modifiers.ToString());
}
