c# - 最初のレコードの実行後に Windows サービスが停止する

Question

レコードをチェックし、そのレコードのレポートを電子メールで送信し、レコードを削除してから、テーブルに対して繰り返すことになっている Windows サービスがあります。レコードをチェックし、最初のレコードのレポートを電子メールで送信してから停止します。何か案は？？

サービスコード:

namespace ReportSender
{

    public partial class EmailReportService : ServiceBase
    {
        private EmailReportApp _app = new EmailReportApp();
        public Timer serviceTimer = new Timer();


        public EmailReportService()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {

            //Set interval (from App Settings) and enable timer 
            serviceTimer.Elapsed += new ElapsedEventHandler(ServiceTimer_OnElapsed);
            //Use Conversion utility to determine next start date/time based on properties, use DateTime.Subtract() to find milliseconds difference between Now and the next start time 
            //serviceTimer.Interval = Date.AddInterval(Properties.Settings.Default.IntervalType, Properties.Settings.Default.Interval).Subtract(DateTime.Now).TotalMilliseconds;
            serviceTimer.Interval = 600000;
            serviceTimer.Enabled = true;

        }

        protected override void OnStop()
        {

            //Stop and disable timer 
            serviceTimer.Enabled = false;
        }

        private void ServiceTimer_OnElapsed(object source, ElapsedEventArgs e)
        {
            try
            {
                //Stop the timer to prevent overlapping runs 
                serviceTimer.Stop();
                //Start service 
                //Run your app.Start() code 
                _app = new EmailReportApp();

                _app.Start();




            }
            catch (Exception ex)
            {

            }
            finally
            {
                //Re-start the timer 
                serviceTimer.Start();
            }
        }

    }
}

サービスが実行するコード:

namespace ReportSender
{
    class EmailReportApp
    {

        // Private fields
        private Thread _thread;
        private EventLog _log;



        private void Execute()
        {

            try
            {

                    // Check for a new record
                    DataClasses1DataContext dc = new DataClasses1DataContext();

                    foreach (var item in dc.reportsSent1s)
                    {
                        string matchedCaseNumber = item.CaseNumberKey;
                        (new MyReportRenderer()).RenderTest(matchedCaseNumber);

                        dc.reportsSent1s.DeleteOnSubmit(item);
                        dc.SubmitChanges();
                    }



            }
            catch (ThreadAbortException ex)
            {
                _log.WriteEntry(ex.StackTrace.ToString());

                }
            }


        public void Start()
        {
            if (!EventLog.SourceExists("EventLoggerSource"))
                EventLog.CreateEventSource("EventLoggerSource", "Event Logger");
            _log = new EventLog("EventLoggerSource");
            _log.Source = "EventLoggerSource";

            _thread = new Thread(new ThreadStart(Execute));
            _thread.Start();
        }
