Schedule Using Quatz .NET

Follow these steps

1. Add a first reference of Quartz.dll in your web application.
2. Create a function which you want to execute repeatedly on a scheduled time.
   
   Call the created function in same class
   
   example
   

   public void Execute(IJobExecutionContext context) {
       this.ScheduledTask();
   }

3. Create a job (ex:name  JobScheduler)(Function).
   
   example
   

   public static void Start() {
       // define the job and tie it to our HelloJob class
       IJobDetail job = JobBuilder.Create < EmailJob > ()
           .WithIdentity("myJob", "group1") // name "myJob", group "group1"
           .Build();
   
       // Trigger the job to run now, and then every 40 seconds
       ITrigger trigger = TriggerBuilder.Create()
           .WithIdentity("myTrigger", "group1")
           .StartNow()
           .WithSimpleSchedule(x => x
               //.WithIntervalInSeconds(300)
               .WithIntervalInMinutes(20)
               .RepeatForever())
           .Build();
   
       // Tell quartz to schedule the job using our trigger
       ISchedulerFactory sf = new StdSchedulerFactory();
       IScheduler sc = sf.GetScheduler();
       sc.ScheduleJob(job, trigger);
       sc.Start();
   }
4. Add Global.asax.
   

   protected void Application_Start(object sender, EventArgs e) {
       JobScheduler.Start();
   }

That's it. Now, when you execute this code, the function will work repeatedly on the scheduled time.
