单个项目中的多个窗口服务=神秘

Question

我有一个奇怪的问题，我没有见过，我认为它必须是简单的东西，我没有在我的代码中看到。

我有一个定义了2个窗口服务的项目。一个我叫DataSyncService，另一个SubscriptionService。两者都被添加到相同的项目安装程序。两者都使用System.Timers中的计时器控件。

如果我一起启动两项服务，它们似乎工作正常。定时器在适当的时间流逝，一切看起来都不错。但是，如果我单独启动其中一项服务，而另一项服务停止，则一切都会失控。定时器不断流逝，并在错误的服务。换句话说，如果我启动DataSyncService，SubscriptionService计时器会一遍又一遍地流逝。这显然很奇怪。

该设置与我在过去所做的类似，所以我真的难倒了。我甚至尝试删除这两个服务并重新开始，但它似乎没有什么区别。在这一点上，我认为我在定义服务的方式上犯了一个简单的错误，而我的大脑不会让我看到它。它必须创建某种线程问题，导致一个服务在另一个服务停止时竞争。下面的代码....

从Program.cs的：

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

     }; 
     ServiceBase.Run(ServicesToRun); 
    } 

从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; 

从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(); 

    } 

从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(); 

    } 

同样，问题是timer1_elapsed处理程序在只有其中一个服务启动时持续运行。它是OPPOSITE服务的处理程序。

有人看到什么吗？

Answer 1

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

this.CanShutdown = true; 

...我不应该有使计时器，因为我在的OnStart处理程序做到这一点。

因此，它应该是这样的：

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(); 

}
