方式一:使用System.Timers.Timer定時器
public partial class Service1 : ServiceBase { private UnitOfWork unitOfWork; private System.Timers.Timer timer1;//初始化一個定時器 LogHelper lghelper = new LogHelper(typeof(Service1)); public Service1() { InitializeComponent(); unitOfWork = new UnitOfWork(); this.timer1 = new System.Timers.Timer(); this.timer1.Interval = 1000;//設置定時器啟動的時間間隔 this.timer1.Elapsed += new System.Timers.ElapsedEventHandler(timer1_Elapsed);//定時器定時執行的方法 } protected override void OnStart(string[] args) { this.timer1.Enabled = true;//服務啟動時開啟定時器 lghelper.Info("服務啟動"); } protected override void OnStop() { this.timer1.Enabled = false;//服務停止時關閉定時器 unitOfWork.Dispose(); lghelper.Info("服務停止"); } private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { this.timer1.Enabled = false;//在服務運行時關閉定時器,避免在服務還沒有運行結束時達到定時器時間間隔又重頭開始運行(比如該定時器設置為5分鍾同步一次數據,當數據量很大時,5分鍾同步不完,這時達到定時器時間間隔,又會重頭開始同步,所以在服務開始運行時關閉定時器) lghelper.Info("服務開始運行"); try { DoWork(); } catch (Exception ex) { lghelper.Error(ex.ToString()); lghelper.Info("服務運行失敗"); Thread.Sleep(5000); } this.timer1.Enabled = true;//服務運行結束,重新啟動定時器 } }
方式二:使用Task
partial class Service2 : ServiceBase, IDisposable { LogHelper lghelper = new LogHelper(typeof(Service2)); private CancellationTokenSource TokenSource = new CancellationTokenSource(); protected UnitOfWork unitOfWork = new UnitOfWork(); Task MainTask; public Service2() { InitializeComponent(); } public void Dispose() { unitOfWork.Dispose(); } protected override void OnStart(string[] args) { lghelper.Info("開啟服務!"); MainTask = Task.Factory.StartNew(() => { while (true) { try { DoWork(); } catch (Exception ex) { lghelper.Error(ex.ToString()); Thread.Sleep(60 * 60 * 1000); } Thread.Sleep(5 * 60 * 1000); } }); } protected override void OnStop() { if (MainTask != null) { if (MainTask.Status == TaskStatus.Running) { } { TokenSource.Cancel(); lghelper.Info("線程結束"); } } } }
方式三:這個方法是看到博友的,還沒有用過,不過覺得挺方便的
