[英]How to get windows unlock event in c# windows application?
I want to track the windows unlock event in a windows application.我想在 Windows 应用程序中跟踪 Windows 解锁事件。 How is it done?
它是如何完成的? What is the event used for that?
事件是用来做什么的? Does I need to import any namespace for that?
我需要为此导入任何命名空间吗?
While a user unlocks the windows, the application needs to do some tasks.当用户解锁窗口时,应用程序需要执行一些任务。
As posted in this StackOverflow answer: https://stackoverflow.com/a/604042/700926 you should take a look at the SystemEvents.SessionSwitch Event .正如在此 StackOverflow 答案中发布的: https : //stackoverflow.com/a/604042/700926您应该查看SystemEvents.SessionSwitch Event 。
Sample code can be found in the referred answer as well.示例代码也可以在参考答案中找到。
I just took the code shown in the referred StackOverflow answer for a spin and it seems to work on Windows 8 RTM with .NET framework 4.5.我只是拿了参考StackOverflow 答案中显示的代码进行了旋转,它似乎可以在带有 .NET 框架 4.5 的 Windows 8 RTM 上运行。
For your reference, I have included the complete sample code of the console application I just assembled.为了您的参考,我已经包含了我刚刚组装的控制台应用程序的完整示例代码。
using System;
using Microsoft.Win32;
// Based on: https://stackoverflow.com/a/604042/700926
namespace WinLockMonitor
{
class Program
{
static void Main(string[] args)
{
Microsoft.Win32.SystemEvents.SessionSwitch += new Microsoft.Win32.SessionSwitchEventHandler(SystemEvents_SessionSwitch);
Console.ReadLine();
}
static void SystemEvents_SessionSwitch(object sender, Microsoft.Win32.SessionSwitchEventArgs e)
{
if (e.Reason == SessionSwitchReason.SessionLock)
{
//I left my desk
Console.WriteLine("I left my desk");
}
else if (e.Reason == SessionSwitchReason.SessionUnlock)
{
//I returned to my desk
Console.WriteLine("I returned to my desk");
}
}
}
}
