單個項目中的多個窗口服務=神祕

Question

我有一個奇怪的問題，我沒有見過，我認爲它必須是簡單的東西，我沒有在我的代碼中看到。

我有一個定義了2個窗口服務的項目。一個我叫DataSyncService，另一個SubscriptionService。兩者都被添加到相同的項目安裝程序。兩者都使用System.Timers中的計時器控件。

如果我一起啓動兩項服務，它們似乎工作正常。定時器在適當的時間流逝，一切看起來都不錯。但是，如果我單獨啓動其中一項服務，而另一項服務停止，則一切都會失控。定時器不斷流逝，並在錯誤的服務。換句話說，如果我啓動DataSyncService，SubscriptionService計時器會一遍又一遍地流逝。這顯然很奇怪。

該設置與我在過去所做的類似，所以我真的難倒了。我甚至嘗試刪除這兩個服務並重新開始，但它似乎沒有什麼區別。在這一點上，我認爲我在定義服務的方式上犯了一個簡單的錯誤，而我的大腦不會讓我看到它。它必須創建某種線程問題，導致一個服務在另一個服務停止時競爭。下面的代碼....

從Program.cs的：

static void Main() 
    { 
     ServiceBase[] ServicesToRun; 
     ServicesToRun = new ServiceBase[] 
     { 
      new DataSyncService(), 
      new SubscriptionService() 

     }; 
     ServiceBase.Run(ServicesToRun); 
    } 

從ProjectInstaller.designer.cs：

private void InitializeComponent() 
    { 
     this.serviceProcessInstaller1 = new System.ServiceProcess.ServiceProcessInstaller(); 
     this.dataSyncInstaller = new System.ServiceProcess.ServiceInstaller(); 
     this.subscriptionInstaller = new System.ServiceProcess.ServiceInstaller(); 
     // 
     // serviceProcessInstaller1 
     // 
     this.serviceProcessInstaller1.Account = System.ServiceProcess.ServiceAccount.LocalSystem; 
     this.serviceProcessInstaller1.Password = null; 
     this.serviceProcessInstaller1.Username = null; 
     // 
     // dataSyncInstaller 
     // 
     this.dataSyncInstaller.DisplayName = "Data Sync Service"; 
     this.dataSyncInstaller.ServiceName = "DataSyncService"; 
     this.dataSyncInstaller.StartType = System.ServiceProcess.ServiceStartMode.Automatic; 
     // 
     // subscriptionInstaller 
     // 
     this.subscriptionInstaller.DisplayName = "Subscription Service"; 
     this.subscriptionInstaller.ServiceName = "SubscriptionService"; 
     this.subscriptionInstaller.StartType = System.ServiceProcess.ServiceStartMode.Automatic; 
     // 
     // ProjectInstaller 
     // 
     this.Installers.AddRange(new System.Configuration.Install.Installer[] { 
     this.serviceProcessInstaller1, 
     this.dataSyncInstaller, 
     this.subscriptionInstaller}); 

    } 

private System.ServiceProcess.ServiceProcessInstaller serviceProcessInstaller1; 
    private System.ServiceProcess.ServiceInstaller dataSyncInstaller; 
    private System.ServiceProcess.ServiceInstaller subscriptionInstaller; 

從DataSyncService.cs：

public static readonly int _defaultInterval = 43200000; 
    //log4net.ILog log; 

    public DataSyncService() 
    { 
     InitializeComponent(); 

     //log = LogFactory.Instance.GetLogger(this); 
    } 

    protected override void OnStart(string[] args) 
    { 
     timer1.Interval = _defaultInterval; //GetInterval(); 
     timer1.Enabled = true; 
     EventLog.WriteEntry("MyProj", "Data Sync Service Started", EventLogEntryType.Information); 
     //log.Info("Data Sync Service Started"); 
    } 

    private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e) 
    { 
     EventLog.WriteEntry("MyProj", "Data Sync Timer Elapsed.", EventLogEntryType.Information); 

    } 

private void InitializeComponent() 
    { 
     this.timer1 = new System.Timers.Timer(); 
     ((System.ComponentModel.ISupportInitialize)(this.timer1)).BeginInit(); 
     // 
     // timer1 
     // 
     this.timer1.Enabled = true; 
     this.timer1.Elapsed += new System.Timers.ElapsedEventHandler(this.timer1_Elapsed); 
     // 
     // DataSyncService 
     // 
     this.ServiceName = "DataSyncService"; 
     ((System.ComponentModel.ISupportInitialize)(this.timer1)).EndInit(); 

    } 

從SubscriptionService：

public static readonly int _defaultInterval = 300000; 
    //log4net.ILog log; 

    public SubscriptionService() 
    { 
     InitializeComponent(); 
    } 

    protected override void OnStart(string[] args) 
    { 
     timer1.Interval = _defaultInterval; //GetInterval(); 
     timer1.Enabled = true; 
     EventLog.WriteEntry("MyProj", "Subscription Service Started", EventLogEntryType.Information); 
     //log.Info("Subscription Service Started"); 
    } 

    private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e) 
    { 
     EventLog.WriteEntry("MyProj", "Subscription Service Time Elapsed", EventLogEntryType.Information); 
    } 

private void InitializeComponent() //in designer 
    { 
     this.timer1 = new System.Timers.Timer(); 
     ((System.ComponentModel.ISupportInitialize)(this.timer1)).BeginInit(); 
     // 
     // timer1 
     // 
     this.timer1.Enabled = true; 
     this.timer1.Elapsed += new System.Timers.ElapsedEventHandler(this.timer1_Elapsed); 
     // 
     // SubscriptionService 
     // 
     this.ServiceName = "SubscriptionService"; 
     ((System.ComponentModel.ISupportInitialize)(this.timer1)).EndInit(); 

    } 

同樣，問題是timer1_elapsed處理程序在只有其中一個服務啓動時持續運行。它是OPPOSITE服務的處理程序。

有人看到什麼嗎？

Answer 1

在Service.Designer.cs文件的InitializeComponent（）方法，我很想念

this.CanShutdown = true; 

...我不應該有使計時器，因爲我在的OnStart處理程序做到這一點。

因此，它應該是這樣的：

private void InitializeComponent() 
{ 
    this.timer1 = new System.Timers.Timer(); 
    ((System.ComponentModel.ISupportInitialize)(this.timer1)).BeginInit(); 
    // 
    // timer1 
    // 

    this.timer1.Elapsed += new System.Timers.ElapsedEventHandler(this.timer1_Elapsed); 
    // 
    // DataSyncService 
    // 
    this.ServiceName = "DataSyncService"; 
    this.CanShutdown = true; 
    ((System.ComponentModel.ISupportInitialize)(this.timer1)).EndInit(); 

}
