在C#中记录登录,注销,系统锁定/解锁事件

Question

我正在计划开发一个应用程序,它可以启动Windows(也许是一个服务)并静默记录用户的登录,注销和系统锁定/解锁事件.

如果有人可以给我一个提示来记录他们的总空闲时间(用户没有执行任何系统活动的时间),这将是非常棒的

我正在寻找一个预先开发的图书馆或能够帮助我顺利完成项目的东西.

尝试下面的代码....

private enum WTS
{
        CONSOLE_CONNECT = 1,
        CONSOLE_DISCONNECT = 2,
        REMOTE_CONNECT = 3,
        REMOTE_DISCONNECT = 4,
        SESSION_LOGON = 5,
        SESSION_LOGOFF = 6,
        SESSION_LOCK = 7,
        SESSION_UNLOCK = 8,
        SESSION_REMOTE_CONTROL = 9
 }

protected override void WndProc(ref System.Windows.Forms.Message m)
{
    switch (m.Msg) {
        case WM_WTSSESSION_CHANGE:
            switch (m.WParam.ToInt32) {
                case WTS.CONSOLE_CONNECT:
                    //MessageBox.Show("A session was connected to the console session.");

                    break;
                case WTS.CONSOLE_DISCONNECT:
                    //MessageBox.Show("A session was disconnected from the console session.");

                    break;
                case WTS.REMOTE_CONNECT:
                    break;
                //MessageBox.Show("A session was connected to the remote session.");
                case WTS.REMOTE_DISCONNECT:
                    break;
                //MessageBox.Show("A session was disconnected from the remote session.");
                case WTS.SESSION_LOGON:

                    break;
                //MessageBox.Show("A user has logged on to the session.")
                case WTS.SESSION_LOGOFF:
                    //MessageBox.Show("A user has logged off the session.");

                    break;
                case WTS.SESSION_LOCK:
                    //MessageBox.Show("A session has been locked.")

                    break;
                case WTS.SESSION_UNLOCK:
                    //MessageBox.Show("A session has been unlocked.")

                    break;
                case WTS.SESSION_REMOTE_CONTROL:
                    MessageBox.Show("A session has changed its remote controlled status. To determine the status, call GetSystemMetrics and check the SM_REMOTECONTROL metric.");
                    break;
            }

            break;
    }

    base.WndProc(m);
}
