推荐答案
做到这一点的方法之一是建立一个钩
的。然后监视消息。
One way to do this is to set up a hook on the external application window withSetWindowHookEx. Then monitor the WM_KEYDOWN message.
我其实不知道它会在C＃中工作，因为钩子回调有可能成为本机DLL。你可能必须写在非托管的语言解决方案的一部分。
I am actually not sure that it will work in C# because the hook callback has to be in a native DLL. You might have to write a portion of the solution in an unmanaged language.
另外，你可以使用的，可能与当前活动窗口的检查相结合。
Alternatively, you could use a global keyboard hook, possibly combined with a check of the currently active window.
