c# - Windows 服务不会安装 server 2003

Question

我正在尝试一个简单的 Windows 服务，它将检查数据库中是否有任何记录，如果是，则运行报告并发送电子邮件，然后删除记录。我尝试安装此服务，但似乎没有安装。该应用程序显示在添加/删除程序中，但服务本身不存在。为什么这不会安装？

这是我的代码。第一部分是实际的服务。

namespace ReportSender
{
    public partial class EmailReportService : ServiceBase
    {
        private EmailReportApp _app = new EmailReportApp();

        public EmailReportService()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            if (_app == null)
                _app = new EmailReportApp();

            _app.Start();
        }

        protected override void OnStop()
        {
            if (_app != null)
                _app.Stop();
        }


    }
}

第二部分是生成然后通过电子邮件发送报告的代码。我在手动版本中使用此代码，因此它应该可以工作。

namespace ReportSender
{
    class EmailReportApp
    {

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



        private void Execute()
        {
            // Loop until the thread gets aborted

            try
            {
                while (true)
                {
                    // 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();

                    // Sleep for one minute 
                    Thread.Sleep(60000);
                }
            }
            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();
        }

        public void Stop()
        {
            if (_thread != null)
            {
                _thread.Abort();
                _thread.Join();
            }
        }

    }
