Question

我的一个项目有不同的要求，当我运行我的exe并让它闲置时（即没有点击，最小，最大），经过一段时间（计时器）后，它应自动关闭。如果有人在特定时间之前点击，则计时器必须在同一时间段内重置。如何判断exe是否空闲？

Answer 1

您可能需要查看Application.Idle事件（注意：据我所知，仅适用于WinForms应用程序）。

如果你将它与一个你的应用程序收到输入时停止/重置的计时器结合起来，这应该可以为你提供你想要的东西。

    }

}

GlobalMouseHandler handle = new GlobalMouseHandler（）; handle.onActive + = new GlobalMouseHandler.EventHandlerForActiveState（handle_onActive）; Application.AddMessageFilter（手柄）; 我用过这个课程并完成了这个。
