Question

我正在尝试创建一个调用库中线程的Windows服务。这一切都在c＃中。该库具有从oracle数据库读取，处理数据，将其存储在SQL Server数据库中并更新oracle数据库中的记录的函数。我对此运行测试，看到循环运行大约80,000次，然后没有抛出任何错误（我甚至检查了事件日志）没有任何反应。请帮忙这是代码

Windows服务

protected override void OnStart(string[] args)
{
    try
    {
        base.OnStart(args);
        controller = new BillingController();
        thread = new Thread(new ThreadStart(controller.dowork));
        thread.Start();
        AppLogs.LogtoFile("SmartCDRBillingService.log", string.Format("SmartCDRBillingService started successfully"));
    }
    catch (Exception ex)
    {
        AppLogs.LogtoFile("SmartCDRBillingService.log", string.Format("Start Service error:  {0}: {1}:", ex.Message.ToString(), ex.InnerException));
    }
}

控制器

public BillingController()
{
    AppConfig.LoadSettings();
}

public void dowork()
{
    try
    {
        BillingQueue nLogic = new BillingQueue();
        nLogic.QueueWorkItems();
    }
    catch (Exception ex)
    {
        //log
        AppLogs.LogtoFile("BillingController.log", string.Format("dowork error:  {0}: {1}:", ex.Message.ToString(), ex.InnerException));
    }
}

队列

public void QueueWorkItems()
{
    new System.Threading.Thread(new System.Threading.ThreadStart(doQueueWork)).Start();
}
private void doQueueWork()
{
    counter = 1;

由Windows服务启动的线程没有错误地停止，但它应该运行无限循环
