推荐答案

我认为你首先必须从你的keydata中提取修饰键，如下所示： />

Hi,

I think you first have to extract only the modifier keys from your keydata like this:

keyData = keyData & Keys.Modifiers; // we are only interested in the modifier keys
if (keyData == (Keys.Shift | Keys.Alt)) //  shift (any) and alt pressed?

我希望这有帮助。

I hope this helps.
