Timed Task Scheduling

In a business complex application, it is sometimes required that one or more tasks are scheduled at a certain time or at a certain time interval, such as scheduled backups or synchronization of databases, sending emails regularly, etc., which we call scheduled tasks.

Timing task Scheduling Implementation method:

1.Windows Service Implementation 2.WebApplication Timer timer task Schedule 3.Windows scheduled Task

But 1,3 can be implemented at a certain time, 2 can only be implemented at a certain time interval.

WebApplication Way:

(1) Thread mode (open threads):

public class Datetimeclass    {public        void Parse ()        {while            (true)            {                int time = Int. Parse (DateTime.Now.ToString ("SS"));                Console.WriteLine (DateTime.Now.ToString ("Yyyy-mm-dd HH:mm:ss") + "   ---  " + time);                Thread.Sleep (3*1000);//Perform task once every 3 seconds            }        } public        void Consolewirte ()        {            ThreadStart ThreadStart = new ThreadStart (this. Parse);            Thread thread = new Thread (ThreadStart);            Thread. Start ();        }    } Class program    {        static void Main (string[] args)        {            new Datetimeclass (). Consolewirte ();        }        }

(2) Timer mode:

Using timer = System.timers.timer;class program    {static void Main (string[] args)        {            Timer timer=new timer ();            timer. Interval = 10000;            Timer. Enabled = true;            Timer. Elapsed + = timer_elapsed;            Console.readkey ();        } static void Timer_elapsed (object sender, System.Timers.ElapsedEventArgs e)        {            new Datetimeclass (). Consolewirte ();        }} public class Datetimeclass    {public        void Consolewirte ()        {            //threadstart ThreadStart = new ThreadStart (this. Parse);            Thread thread = new Thread (ThreadStart);            Thread. Start ();            Console.WriteLine (DateTime.Now.ToString ("Yyyy-mm-dd HH:mm:ss") + "   ---  " + 1);        }    }
