Quartz: Why does this Trigger not fire?

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

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.
