Quartz: Why does this Trigger not fire? - quartz.net

Question

I am using quartz.NET in my project. I have the following problem. I want to run a Scheduled task everyday at 23 o'clock and I am using this code to do that:
public class HelloJob : IJob
{
public void Execute(IJobExecutionContext context)
{
//Download file
}
}
public interface ISchedule
{
void Run();
}
public class HelloSchedule : ISchedule
{
public void Run()
{
IJobDetail job = JobBuilder.Create<HelloJob>()
.WithIdentity("job1")
.Build();
ITrigger trigger = TriggerBuilder.Create()
.ForJob(job)
.WithIdentity("trigger1")
.StartNow()
.WithCronSchedule("0 0 23 ? * MON-FRI *")
.Build();
ISchedulerFactory sf = new StdSchedulerFactory();
IScheduler sc = sf.GetScheduler();
sc.ScheduleJob(job, trigger);
sc.Start();
}
}
but unfortunately it's not firing.
How can I know what the problem is and solve it?
Thanks for your advice

Answer 1

Your job will fire at 11pm.
You can check the next fire time for you job using this code:
private static DateTime getNextFireTimeForJob(IScheduler scheduler, string jobName, string groupName = "")
{
JobKey jobKey = null;
if (!string.IsNullOrEmpty(groupName))
{
jobKey = new JobKey(jobName, groupName);
}
else
{
jobKey = new JobKey(jobName);
}
DateTime nextFireTime = DateTime.MinValue;
bool isJobExisting = Scheduler.CheckExists(jobKey);
if (isJobExisting)
{
var detail = scheduler.GetJobDetail(jobKey);
var triggers = scheduler.GetTriggersOfJob(jobKey);
var myTrigger = triggers.Where(f => f.Key.Name == "SecondTrigger").SingleOrDefault();
if (triggers.Count > 0)
{
var nextFireTimeUtc = triggers[0].GetNextFireTimeUtc();
nextFireTime = TimeZone.CurrentTimeZone.ToLocalTime(nextFireTimeUtc.Value.DateTime);
}
}
return (nextFireTime);
}
and get the info using this:
var nextFireTime = getNextFireTimeForJob(sc, "job1");
Make sure your HelloJob implements IJob.
If you're integrating your Quartz.net scheduler in a WinApp make sure it's created singleton cause it might be destroyed when it goes out of scope.
I test my jobs in a console application and use Console.ReadLine(); to wait the jobs execution.

Use org.Quartz and try this:
JobDetail job = new JobDetail();
job.setName(Constants.JOB_NAME);
job.setJobClass(YOUR_JOB_CLASS.class);
CronTrigger trigger = new CronTrigger();
trigger.setName(Constants.TRIGGER_NAME);
trigger.setCronExpression("0 0 23 ? * MON-FRI *");
// schedule it
Scheduler scheduler = new StdSchedulerFactory().getScheduler();
scheduler.start();
scheduler.scheduleJob(job, trigger);
Your Job class should implement org.Quartz.Job interface and override its execute method which does the actual thing the job needs to perform.
