C# - 检测上次用户与操作系统交互的时间 [英] C# - Detect time of last user interaction with the OS

问题描述

我正在编写一个小型托盘应用程序，需要检测用户上次与其机器交互的时间，以确定他们是否空闲.

I'm writing a small tray application that needs to detect the last time a user interacted with their machine to determine if they're idle.

有什么方法可以检索用户上次移动鼠标、击键或以任何方式与机器交互的时间吗?

Is there any way to retrieve the time a user last moved their mouse, hit a key or interacted in any way with their machine?

我认为 Windows 显然会跟踪它以确定何时显示屏幕保护程序或关闭电源等，所以我假设有一个 Windows API 可以自己检索它?

I figure Windows obviously tracks this to determine when to display a screen saver or power down, etc, so I'm assuming there's a Windows API for retrieving this myself?

推荐答案

GetLastInputInfo.记录在 PInvoke.net.
