A good head is worse than a rotten pen.-quartz Use Summary

Quartz is an open-source job scheduling framework for the Java platform. Quartz.net is a convenient time to use Quartz to perform scheduled tasks such as batch processing, from a Java version to a. NET version of a. NET project.

(1) Quartz.net can be installed from NuGet

(2) Quartz configuration:

<configsections>  < Sectionname= "Quartz"type= "System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,culture=neutral, publickeytoken= b77a5c561934e089 "/></configsections><Quartz>  <AddKey= "Quartz.scheduler.instanceName"value= "Exampledefaultquartzscheduler"/>  <AddKey= "Quartz.threadPool.type"value= "Quartz.Simpl.SimpleThreadPool, Quartz"/>  <AddKey= "Quartz.threadPool.threadCount"value= "Ten"/>  <AddKey= "Quartz.threadPool.threadPriority"value= "2"/>  <AddKey= "Quartz.jobStore.misfireThreshold"value= "60000"/>  <AddKey= "Quartz.jobStore.type"value= "Quartz.Simpl.RAMJobStore, Quartz"/></Quartz><appSettings>  <!--cronexpression expression: Starts at the 2nd second of every minute and executes 5 seconds every interval -  <AddKey= "cronexpr"value= "2/5 * * * * *?"/></appSettings>

(3) Create a generic class to implement the Quartz.ijob interface

The interface is simple, there is only one execute () method (as in Java), in which you write the processing logic you want to do.

 Public class myjob:quartz.ijob{    publicvoid  Execute (quartz.ijobexecutioncontext context)    {        //  your processing logic, i.e. "work"        Console.WriteLine (DateTime.Now);    }}

(4) Start job scheduling

Using Quartz;
Using Quartz.impl;
Using Quartz.Impl.Triggers;

classprogram{Static voidMain (string[] args) {                    //Initializes a new instance of the Quartz.Impl.StdSchedulerFactory class.Ischedulerfactory SF =NewQuartz.Impl.StdSchedulerFactory (); //Returns a client-usable handle to a quartz.ischeduler.IScheduler sched =SF.            Getscheduler (); //define a job (i.e. your processing logic, i.e. "work")Ijobdetail job =NewJobdetailimpl ("Job1","group1",typeof(MyJob)); //defining triggers (reading appsettings)            stringcronexpr = configurationmanager.appsettings["cronexpr"]; Itrigger Trigger=NewCrontriggerimpl ("Trigger1","group1","Job1","group1", cronexpr); //add a given job to the schedulerSched. AddJob (Job,true,true); //assigning a trigger to a jobSched.            Schedulejob (trigger); //start the Scheduler threadSched.            Start ();    Console.read (); }}

I am here a console program. For a Web program or service program, when Application_End, you need to call Scheduler's shutdown () method to turn off Quartz's work.

Note that the IScheduler has two overloaded AddJob methods:

namespacequartz{ Public InterfaceIScheduler {//        //Summary://Add The given quartz.ijob to the Scheduler-with no associated quartz.itrigger. //the quartz.ijob'll be ' dormant ' until it's scheduled with a Quartz.itrigger,//or Quartz.IScheduler.TriggerJob (Quartz.jobkey) is called for it. //        //remark://the quartz.ijob must by definition being ' durable ', if it is not, schedulerexception//would be thrown.        voidAddJob (Ijobdetail Jobdetail,BOOLreplace); //        //Summary://Add The given quartz.ijob to the Scheduler-with no associated quartz.itrigger. //the quartz.ijob'll be ' dormant ' until it's scheduled with a Quartz.itrigger,//or Quartz.IScheduler.TriggerJob (Quartz.jobkey) is called for it. //        //remark://with the storenondurablewhileawaitingscheduling parameter set to True, a//non-durable job can be stored. Once It is scheduled, it would resume normal//non-durable behavior (i.e. be deleted once there is no remaining associated//triggers).        voidAddJob (Ijobdetail Jobdetail,BOOLReplaceBOOLstorenondurablewhileawaitingscheduling); }}

Above the addjob to call void AddJob (Ijobdetail jobdetail, BOOL Replace, BOOL storenondurablewhileawaitingscheduling); Set the torenondurablewhileawaitingscheduling parameter to True. Otherwise, the Schedulerexception exception is thrown:

quartz.schedulerexception HResult not processed=-2146233088Message=Jobs added with no trigger must is durable.

(5) Next, you can allow the program to see the effect.
