C# Windows 服务无法将关机事件记录到远程 API

Question

我正在生成一个 C# windows 服务来记录特定的 windows 事件。虽然它们中的大多数都很好（Logon/off、Lock/Unlock 等），但我在 Windows 断电类型事件方面遇到了一些问题。我正在尝试的代码如下所示（摘自其他地方的其他建议）。

对于服务：-

public Service()
        {
            InitializeComponent();
            SystemEvents.SessionEnded += new SessionEndedEventHandler(SystemEvents_SessionEnded);
            SystemEvents.PowerModeChanged += new PowerModeChangedEventHandler(SystemEvents_PowerModeChanged);

        }

对于SystemEvents_SessionEnded：-

void SystemEvents_SessionEnded(object sender, SessionEndedEventArgs e)
        {
            switch (e.Reason)
            {
                case SessionEndReasons.SystemShutdown:
                    eventType = 7;
                    break;
                case SessionEndReasons.Logoff:
                    eventType = 2;
                    break;
                default:
                    break;
            }

            \Send eventType and current DateTime to remote API
        }

而 SystemEvents_PowerModeChanged

static void SystemEvents_PowerModeChanged(object sender, PowerModeChangedEventArgs e)
        {
            switch (e.Mode)
            {
                case PowerModes.Suspend:
                    eventType = 5;
                    break;
                case PowerModes.Resume:
                    eventType = 6;
                    break;
                default:
                    break;
            }

            \Send eventType and current Datetime to API
        }

由于 API 在本地机器外部托管，我假设我的服务依赖于其他人通过网络发送数据？关于是我的代码失败了还是我是否需要更好的依赖项设置，有什么建议吗？

提前致谢。

SessionEnded Docs 说：

This event is only raised if the message pump is running. In a Windows service, unless a hidden form is used or the message pump has been started manually, this event will not be raised. For a code example that shows how to handle system events by using a hidden form in a Windows service, see the SystemEvents class.
