c# – Windows服务自动启动和停止,异常处理问题

我开发了32位服务,我在Windows 7 Home Premium x64中运行它.
问题是,当我启动它时,Windows会给我以下消息

The WLConsumer service on Local Computer started and then stopped. Some services stop
automatically if they are not in use by other services or programs.

我在事件日志中找到了以下消息

Service cannot be started. System.ArgumentException: Log WLConsumer has already been registered as a source on the local computer.

at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)

这是我在OnStart()方法中的代码块

   protected override void OnStart(string[] args)
    {
        #region WEBLOGIC CREDENTIALS
        try
        {
            //Weblogic URL
            this.url = Registry.LocalMachine.OpenSubKey(@"Software\CSI_WL").GetValue("URL").ToString();

            //Queue name
            this.qName = Registry.LocalMachine.OpenSubKey(@"Software\CSI_WL").GetValue("Queue").ToString();

            //Weblogic login name
            this.user = Registry.LocalMachine.OpenSubKey(@"Software\CSI_WL").GetValue("User").ToString();

            //Weblogic password
            this.pwd = Registry.LocalMachine.OpenSubKey(@"Software\CSI_WL").GetValue("Pwd").ToString();

            //Weblogic Connection Factory
            this.cfName = Registry.LocalMachine.OpenSubKey(@"Software\CSI_WL").GetValue("ConnectionFactory").ToString();

            //root folder
            this.rFolder = Registry.LocalMachine.OpenSubKey(@"Software\CSI_WL").GetValue("root").ToString();
        }
        catch (Exception e)
        {
            winEventlogMe(e.Message, "WLRegistryKeys", 'e');
        }
        #endregion

        winEventlogMe("Successful start", "SeriviceStartup", 'i');
        synchro.Enabled = true;
    }

winEventLogMe是我要求记录的方法.

        public static void winEventlogMe(string logTxt, string logSrc, char entryType)
    {
        #region Log
        //Log to event log

        EventLog theEvent = new EventLog("WLConsumer");
        theEvent.source = logSrc;
        if (entryType == 'e')
            theEvent.WriteEntry(logTxt, EventLogEntryType.Error);
        else if (entryType == 'i')
            theEvent.WriteEntry(logTxt, EventLogEntryType.information);
        else if (entryType == 'w')
            theEvent.WriteEntry(logTxt, EventLogEntryType.Warning);
        else
            theEvent.WriteEntry(logTxt, EventLogEntryType.Error);*/
        #endregion
    }

当我在OnStart()方法中注释掉对winEventLogMe()方法的调用时,服务启动时没有错误.所以winEventLogMe()方法显然有问题.
有人可以帮我弄清楚问题是什么,因为我现在对如何解决这个问题完全无能为力.
