C# windows服务中未调用计时器勾选事件

我有一个窗口服务，它在指定的时间播放声音文件，所以我使用了计时器，但它的滴答声事件从未触发，这在WinForm应用程序中也起作用

下面是我的服务的代码片段

public partial class ClockService : ServiceBase
{
    private TimeSpan _alarmTime = new TimeSpan(9, 55, 0);
    private int _snoozeTime = 2; // 2 minutes
    private int _repeatCounter = -1;
    private const int ALARM_REPETITION = 5;
    private string _alarmSoundPath = @"C:\Sound\default.wav";
    private string _alarmLogPath = @"C:\Sound\log.txt";

    public ClockService()
    {
        InitializeComponent();
        alarmTimer.Enabled = true;
    }

    protected override void OnStart(string[] args)
    {
        using (FileStream fileStream = new FileStream(_alarmLogPath, FileMode.OpenOrCreate))
        {
            using (StreamWriter writer = new StreamWriter(fileStream))
            {
                writer.WriteLine("Service has started at {0}", DateTime.Now);
            }
        }
    }

    protected override void OnStop()
    {
        using (FileStream fileStream = new FileStream(_alarmLogPath, FileMode.OpenOrCreate))
        {
            using (StreamWriter writer = new StreamWriter(fileStream))
            {
                writer.WriteLine("Service has stopped at {0}", DateTime.Now);
            }
        }
    }

    private void alarmTimer_Tick(object sender, EventArgs e)
    {
        using (FileStream fileStream = new FileStream(_alarmLogPath, FileMode.OpenOrCreate))
        {
            using (StreamWriter writer = new StreamWriter(fileStream))
            {
                writer.WriteLine("Alarm time is: {0}", _alarmTime);
            }
        }

        TimeSpan currentTime = new TimeSpan(DateTime.Now.TimeOfDay.Hours, DateTime.Now.TimeOfDay.Minutes, DateTime.Now.TimeOfDay.Seconds);


        if (currentTime == _alarmTime)
        {
            using (FileStream fileStream = new FileStream(_alarmLogPath, FileMode.OpenOrCreate))
            {
                using (StreamWriter writer = new StreamWriter(fileStream))
                {
                    writer.WriteLine("Alarm time is: {0} and current time is: {1}", _alarmTime, currentTime);
                }
            }

            _alarmTime = _alarmTime.Add(new TimeSpan(0, _snoozeTime, 0));
            _repeatCounter++;

            if (File.Exists(_alarmSoundPath))
            {
                SoundPlayer player = new SoundPlayer(_alarmSoundPath);
                player.PlayLooping();
            }

        }

        if (_repeatCounter == ALARM_REPETITION)
        {
            _alarmTime = _alarmTime.Subtract(new TimeSpan(0, (ALARM_REPETITION * _snoozeTime), 0));
            _repeatCounter = 0;
        }

    }
}

为了确保我已经正确地完成了所有工作，下面是我的InitializeComponent方法

    private void InitializeComponent()
            {
                this.components = new System.ComponentModel.Container();
                this.alarmTimer = new System.Windows.Forms.Timer(this.components);
                this.alarmTimer.Enabled = true;
                this.alarmTimer.Interval = 1000; 
            this.alarmTimer.Tick += new System.EventHandler(this.alarmTimer_Tick);
        this.ServiceName = "PravoAlarmService";
    }

请任何人看一下并指导我…问题是滴答声事件从未触发。

尝试使用

系统.Timers.Timer

this.alarmTimer = new System.Timers.Timer();

---

System.Windows.Forms.Timer

（顾名思义）可以在表单应用程序中工作，但不能在NT服务中工作。

不要使用System.Windows.Forms.Timer，使用System.Threading.Timer

---

服务不是一种形式。

我认为System.Timers.Timer是一个更好的选择：

Timer _timer = new Timer();
// In miliseconds 60000 = 1 minute
// This timer will tick every 1 minute
_timer.Interval += 6000;
// Activate the timer
_timer.Enabled = true;
// When timer "tick"
_timer.Elapsed += new ElapsedEventHandler(_timer_Elapsed);

尝试使用其他计时器：）

您确定问题出在计时器上吗？windows服务访问声音系统是极不寻常的，（您将如何关闭它？）

话虽如此，TomTom是对的，表单计时器是关于能够封送到UI线程的，而您没有，而是使用线程计时器
