推荐答案

KeyEventArgs具有2个布尔值-Alt和Control.

使用KeyDown事件进行检查.

KeyEventArgs has 2 booleans for that - Alt and Control.

Use KeyDown event to check for that.

private void Form1_KeyDown(object sender, KeyEventArgs e)
       {

               if (e.Alt || e.Control)
               {
                // do somethings
               }

       }

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Control && e.Alt)
    {
        MessageBox.Show("Ctrl + Alt pressed");
    }
}
