推荐答案

和多一点点：

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" );
}
