Microsoft Windows Service (3) uses Quartz.net to schedule tasks,

Quartz is another open-source project of OpenSymphony open-source organization in the Job scheduling field. Quartz.net is the transplanted version of Quartz. Quartz can be used to create complex programs such as simple or running ten, hundreds, or even tens of thousands of Jobs.

Official website tutorial: http://www.quartz-scheduler.net/documentation/index.html

　　

Advantages:

1. Full, start time, interval, times, and end time can be specified.

2. Convenient. There is no need to consider various thread issues.

 

Download:

Install-Package Quartz

　　

　　

 

Development:

1. job 2. trigger 3. scheduler

 

 

Job: a task item that defines the tasks to be executed.

There is only one method to implement the IJob interface.

　　

class SampleJob : IJob    {        public void Execute(IJobExecutionContext context)        {            File.AppendAllText("d:\\1.txt", "good");        }    }

 

Trigger: the trigger that defines when to execute multiple times..

Constructor: public SimpleTriggerImpl (string name, string group, DateTimeOffset startTimeUtc, DateTimeOffset? EndTimeUtc, int repeatCount, TimeSpan repeatInterval );

　　

You can use the above ctor to create a new call trigger.

 

 

Sched: scheduler, which schedules the combination of triggers and tasks.

　　

var factory = new StdSchedulerFactory();var sched = factory.GetScheduler();

 

Run:

A. Wrap the IJob into IJobDetail and use public JobDetailImpl (string name, Type jobType );

B. Scheduling Method for calling the ischedoffset interface: DateTimeOffset ScheduleJob (IJobDetail jobDetail, ITrigger trigger );

C. Call the ischedayinterface to Start the method: void Start (); or void StartDelayed (TimeSpan delay );

　　

 

Stop:

Call the ischeddown interface start method: void Shutdown ();

Use Quartz and TopShelf to create a service:

1 class Program 2 {3 static void Main (string [] args) 4 {5 HostFactory. run (x => 6 {7 // the service to be configured 8 x. service <RuntimeService> (c => 9 {10 c. constructUsing (name => new RuntimeService (); 11 c. whenStarted (s => s. begin (); 12 c. whenStopped (s => s. stop (); 13}); 14 // Service Running identity 15 x. runAsLocalSystem (); 16 17 x. setDescription ("service description"); 18 x. setDisplayName ("display name"); 19 x. setServiceName ("service name"); 20}); 21} 22} 23 24 class RealJob: IJob25 {26 public void Execute (IJobExecutionContext context) 27 {28 Console. writeLine (DateTime. now. toLongTimeString (); 29} 30} 31 32 class RuntimeService33 {34 private isched1_sched; 35 public RuntimeService () 36 {37 var factory = new StdSchedulerFactory (); 38 sched = factory. getScheduler (); 39} 40 public void Begin () 41 {42 sched. scheduleJob (new JobDetailImpl ("job", typeof (RealJob), 43 new SimpleTriggerImpl ("trig", "group",-1, new TimeSpan (0, 0, 1); 44 sched. start (); 45} 46 47 public void Stop () 48 {49 sched. shutdown (); 50} 51}
