我知道我需要使用e.KeyData来自KeyEventArgs中,Keys枚举和一些与枚举标志和位,但我不知道如何检查相结合.

您需要使用KeyEventArgs类的Modifiers属性.

就像是:

//asumming e is of type KeyEventArgs (such as it is 
// on a KeyDown event handler
// ..
bool ctrlShiftM; //will be true if the combination Ctrl + Shift + M is pressed, false otherwise

ctrlShiftM = ((e.KeyCode == Keys.M) &&               // test for M pressed
              ((e.Modifiers & Keys.Shift) != 0) &&   // test for Shift modifier
              ((e.Modifiers & Keys.Control) != 0));  // test for Ctrl modifier
if (ctrlShiftM == true)
{
    Console.WriteLine("[Ctrl] + [Shift] + M was pressed");
}
