我如何获得PC电源关闭的时间? [英] How i can get the time of PC Power OFF ?

问题描述

我正在建立考勤系统，所以当用户单击登录和注销"按钮时，我将使用登录时间和注销时间.

但是我还有另一种情况，如果PC断电，这意味着我将存储登录时间，而注销时间将不会设置，因此我想将断电时间视为注销时间，我该如何获取这次.

I am Making attendance System so I''m take the time of log in and the time of log out when user click on Login and Logout button .

but i have another scenario if power off on PC this mean i will store the time of log in and the time of log out will not set so i want to consider the time of power off to be the time of log out how i can get this time.

推荐答案

您可能需要实现

You will probably need to implement OnShutdown()[^] method, or similar.

创建Windows服务并将所需的信息记录到服务器计算机上的外部数据库中.

简单Windows服务示例 [

Create a windows service and log the information you require to an external database on a server machine.

Simple Windows Service Sample[^]

如果我正确理解了您的问题，我想您希望跟踪突然断电的时间，系统上会发生硬关闭，因此系统事件日志中不会有任何条目.我唯一的建议是，您使用Mehdi的建议来创建一个简单的服务，该服务每分钟左右将内容写入外部数据库，如果发生此类事件，您将在一分钟之内准确无误.

If I understand your question correctly, I think you want to be able to trace the time at which a sudden power loss, hard shut down occurs on the system whereby there won''t be an entry in the system event logs. The only suggestion I would have is that you use Mehdi''s suggestion to create a simple service that writes something every minute or so to an external database by which you will then be accurate to within a minute if such an event occurs.
