C#监听锁屏代码

今天，偶然间在技术群看有人问，怎么监听锁屏。

在此处记录一下

public class Constrctor
    {
        public Constrctor()
        {
            SystemEvents.SessionSwitch += new SessionSwitchEventHandler(SystemEvents_SessionSwitch);
        }

        ~Constrctor()
        {
            Microsoft.Win32.SystemEvents.SessionSwitch -= new SessionSwitchEventHandler(SystemEvents_SessionSwitch);
        }

        void SystemEvents_SessionSwitch(object sender, SessionSwitchEventArgs e)
        {
            switch (e.Reason)
            {
                case SessionSwitchReason.SessionLogon:
                    Console.WriteLine("用户登录");
                    break;

                case SessionSwitchReason.SessionUnlock:
                    Console.WriteLine("解锁");
                    break;

                case SessionSwitchReason.SessionLock:
                    Console.WriteLine("锁屏");
                    break;
                case SessionSwitchReason.SessionLogoff:
                    Console.WriteLine("注销");
                    break;
            }
        }
    }
