c# - 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，它以 Windows(也许是一项服务)启动并静默记录用户的登录、注销和系统锁定/解锁事件。

如果有人能给我一个提示来记录他们的总空闲时间(用户没有执行系统事件的时间)，那就太棒了

我正在寻找一个预开发的库或可以帮助我顺利完成项目的东西。

试试下面的代码....

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);
}
