【问题描述】：

我有一个非常简单的窗口服务，我是按照本教程开发的：http://www.c-sharpcorner.com/UploadFile/naresh.avari/develop-and-install-a-windows-service-in-C-Sharp/

但是我注意到 ElapsedEventHandler 从未像教程那样被触发：

  public partial class Scheduler : ServiceBase
    
        public Timer timer1 = null;
        public Scheduler()
        
            InitializeComponent();
        

        protected override void OnStart(string[] args)
        

            timer1 = new Timer();
            this.timer1.Interval = 30000;
            this.timer1.Elapsed+=new ElapsedEventHandler(this.timer1_Tick);
            Library.WriteErrorLog("Test Window service started");

        

        protected override void OnStop()
        
            timer1.Enabled = false;
            Library.WriteErrorLog("test window service stopped");
        

        private void timer1_Tick(object sender, ElapsedEventArgs e)
        
            Library.WriteErrorLog("Timer ticked and some job has been done successfully");
        
    

【参考方案1】：

您必须启用计时器。有关示例，请参阅here。你提到的文章也是这样做的。

timer1.Enabled = true;
