C#：从 KeyEventArgs 的 KeyData 获取正确的按键

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

我知道我需要使用e.KeyData来自KeyEventArgs, the Keys枚举以及带有枚举标志和位的东西，但我不确定如何检查组合。

您需要使用修饰符 http://msdn.microsoft.com/en-us/library/system.windows.forms.keyeventargs.modifiers.aspxKeyEventArgs 类的属性。

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");
}
