Windows Services Simple Instance

1. Timer use

    Partial classTimerservice:servicebase { PublicTimerservice () {InitializeComponent (); } Timer Timer=NewTimer (); protected Override voidOnStart (string[] args) {            //TODO: Add code here to start the service. Addlog ("* * * Service started"); Timer. Elapsed+=timer_elapsed; Timer. Interval= +; Timer.        Start (); }        intNumber =0; voidTimer_elapsed (Objectsender, Elapsedeventargs e) {            Try{ number++; Addlog ("Section"+ number +"Secondary Execution Method"); Addlog ("Current Time:"+DateTime.Now.ToLongTimeString ()); }            Catch(Exception) {}}protected Override voidOnStop () {//TODO: Add code here to perform the close operation required to stop the service. Addlog ("* * * Service terminated"); Timer.        Stop (); }         Public voidAddlog (stringstr) {            using(StreamWriter SW =NewStreamWriter (@"G:\log.data",true) ) {SW. WriteLine ("****************************************"); Sw.            WriteLine (str); }        }    }

2. Logging and database access

    Partial classmessageboxser:servicebase {Thread mainthread;  PublicMessageboxser () {InitializeComponent (); Mainthread=NewThread (NewThreadStart (ThreadFunc)); Mainthread.priority=Threadpriority.normal; }                 Public Static voidThreadFunc () {//While (true)//{            //Thread.Sleep (1000); //MessageBox.Show ("asdfasdf"); //}             while(true)            {                //MessageBox.Show ("asdfasdf");Thread.Sleep ( the); //Modify DatabaseSertableda.adddata (); //Record Log//Try//{                //using (StreamWriter SW = new StreamWriter (@ "G:\log.data", true))//    {                //SW.                WriteLine (DateTime.Now.ToLongTimeString () + "Execute loop Code"); //    }                //}                //catch (Exception ex)//{                //}            }        }        protected Override voidOnStart (string[] args) {            //TODO: Add code here to start the service. Mainthread.start (); }        protected Override voidOnStop () {//TODO: Add code here to perform the close operation required to stop the service. Mainthread.abort (); }    }
