.net - Quartz: repeat job always on monday through friday -

i have next trigger:

var resumetaskstrigger = triggerbuilder.create()     .withidentity("resumetaskstrigger", "tasks")     .startat(datebuilder.futuredate(15, intervalunit.second))     .withschedule(         dailytimeintervalschedulebuilder         .create()         .onmondaythroughfriday())     .build(); 

should trigger works every week or once? if it's right, can't figure out how set intifinity repeat ischedulebuilder?

it run forever unless specify end date:

itrigger resumetaskstrigger = triggerbuilder.create()     .withidentity("resumetaskstrigger", "tasks")     .startat(datebuilder.futuredate(15, intervalunit.second))     .endat(datebuilder.futuredate(10, intervalunit.year))     .withschedule(         dailytimeintervalschedulebuilder         .create()         .onmondaythroughfriday()         .withintervalinminutes(30)         .startingdailyat(timeofday.hourandminuteofday(10, 0))         .endingdailyat(timeofday.hourandminuteofday(12, 0))         )     .build(); 

you can use code check schedules defined trigger:

    private static void getnextxfiretimes(itrigger trigger, int triggerscount)     {         console.writeline(string.format("list of next {0} schedules: ", triggerscount.tostring()));          var dt = trigger.getnextfiretimeutc();          using (var file = new system.io.streamwriter(@"e:\temp\quartz.net.log.log"))         {             (int = 0; < triggerscount; i++)             {                 if (dt == null)                     break;                  file.writeline(dt.value.tolocaltime().tostring());                  dt = trigger.getfiretimeafter(dt);             }           }     }
