Windows服务时间控件怎么调试

　　写了timer,调试的话在构造函数里面把Elapsed方法写成null,null就可以调试了

     public PSJCService()
        {
            InitializeComponent();
            GetuserInfo();
            timer2 = new System.Timers.Timer();
            timer2.Interval = ;
            timer2.Elapsed += new System.Timers.ElapsedEventHandler(timer2_Elapsed);
            timer2_Elapsed(null,null);
            timer = new System.Timers.Timer();
            timer.Interval =  * int.Parse(ConfigurationManager.AppSettings["RealTimeInterval"].ToString());
            timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);
            timer_Elapsed(null, null);

        }
