Question

好的，所以我正在尝试编写一个程序来跟踪我在玩游戏时的按键操作，以便我可以稍后分析数据以帮助我改进游戏。我一直在尝试使用user32.dll的RegisterHotKey实现Global Hotkey Hook。但这完全捕捉了击键，游戏不再接受击键。我不知道从哪里开始，任何指针都会非常感激。以下是一些其他信息：

我正在使用C＃
.NET 4
使用Visual Studio 2010
我不是试图做任何违法的事情，或者反对游戏TOS

       return CallNextHookEx(_hookID, nCode, wParam, lParam);
}

   [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
   private static extern IntPtr SetWindowsHookEx(int idHook,

   [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]

   [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
   private static extern IntPtr GetModuleHandle(string lpModuleName);
}
