C＃：充分利用KeyEventArgs“KEYDATA按下正确的键

问题描述

我诱捕的KeyDown 事件，我需要能够检查当前键是否按下如下：控制 + 移 + M ？

I am trapping a KeyDown event and I need to be able to check whether the current keys pressed down are : + + ?

---

我知道我需要使用 e.KeyData 从 KeyEventArgs 的键枚举和枚举标志和位的东西，但我不知道如何检查相结合。

I know I need to use the e.KeyData from the KeyEventArgs, the Keys enum and something with Enum Flags and bits but I'm not sure on how to check for the combination.

喜欢的东西：

//asumming e is of type KeyEventArgs (such as it is 
// on a KeyDown event handler
// ..
bool ctrlShiftM; //will be true if Ctrl + Shit + 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");
}
