如何从一个WPF应用程序检测锁定该计算机的命令? [英] How do I detect a Lock This Computer command from a WPF application?
问题描述
宁愿在C#中的答案,NET 3.5的使用WPF(Windows窗体也没关系)
Would prefer an answer in C#, .Net 3.5 using WPF (Windows Forms also okay)
我有一个应用程序,它本质上是一个工具栏窗口或托盘图标。它需要,如果用户锁定他/她的工作站,并在为了更新该人在一个集中的系统状态走开以检测
I have an application that is essentially a toolbar window or tray icon. It needs to detect if a user locks his/her workstation and walks away in order to update the person's status in a centralized system.
我可以检测会话开关或注销很轻松地使用SystemEvents,但我不能为我的生活弄清楚如何检测或接收锁定的事件。
I can detect a session switch or a logout easily enough, using the SystemEvents, but I cannot for the life of me figure out how to detect or receive an event on Lock.
感谢您的任何帮助。
推荐答案
在处理的 Microsoft.Win32.SystemEvents.SessionSwitch
事件(这听起来像你已经做检测注销),请检查是否原因
是的 SessionSwitchReason
.SessionLock
:
using Microsoft.Win32;
// ...
// Somewhere in your startup, add your event handler:
SystemEvents.SessionSwitch +=
new SessionSwitchEventHandler(SystemEvents_SessionSwitch);
// ...
void SystemEvents_SessionSwitch(object sender, SessionSwitchEventArgs e)
{
switch(e.Reason)
{
// ...
case SessionSwitchReason.SessionLock:
// Do whatever you need to do for a lock
// ...
break;
case SessionSwitchReason.SessionUnlock:
// Do whatever you need to do for an unlock
// ...
break;
// ...
}
}
