c# - What happens when quartz sheduler becomes out of scope? -

what happens when quartz sheduler becomes out of scope? garbage collector kills or keep running? samle code:

namespace quartz_test {     public class simplejob : ijob     {         public void execute(ijobexecutioncontext context)         {             console.writeline("hello there");         }     }      class program     {         static void scheduletask()         {             // construct scheduler factory             ischedulerfactory schedfact = new stdschedulerfactory();             // scheduler             ischeduler scheduler = schedfact.getscheduler();             scheduler.start();             ijobdetail job = jobbuilder.create<simplejob>()                 .withidentity("myjob", "group1")                 .build();             itrigger trigger = triggerbuilder.create()                 .withsimpleschedule(x => x.withintervalinseconds(10).withrepeatcount(3))                 .build();             scheduler.schedulejob(job, trigger);         }          static void main(string[] args)         {             scheduletask();             //link scheduler lost here             //how stop simplejob execution?             //console.readline();         }     } 

this code outputs:

hello there hello there hello there 

all seems ok, why program never finish if comment last console.readline();?

and last question: how stop ijob execution if lost links sceduler

there shutdown method in library.

syntax

void shutdown( bool waitforjobstocomplete); 

you can use it.

ischeduler scheduler = schedfact.getdefaultscheduler(); scheduler.shutdown(false); 

you can use either unschedulejob or deletejob method.

scheduler.unschedulejob(new triggerkey("myjob", "group1")); 

or

scheduler.deletejob(new jobkey("myjob", "group1"));
