Quartz Scheduler 的作业已触发，但 JobListener 未拾取事件

几天来我一直在努力使这项工作。我正在尝试使用石英调度程序在我的主窗体上触发一个事件，可以从中调用一个方法。我的主窗体上的代码如下：

void StartSchedule()
{
    string AuctionTime = "0 0 0 ? * MON-FRI *";
    JobKey jobkey = new JobKey("Auction", "G");
    IJobDetail job = JobBuilder.Create<AuctionJob>()
                                .WithIdentity(jobkey)
                                .Build();
    CronScheduleBuilder csb = CronScheduleBuilder.CronSchedule(new CronExpression(AuctionTime)).InTimeZone(TimeZoneInfo.Local);
    ICronTrigger trigger = (ICronTrigger)TriggerBuilder.Create()
                                                        .WithIdentity("Auction-Trigger", "G")
                                                        .WithSchedule(csb)
                                                        .Build();
    // Create listener
    JobListener auctionListener = new JobListener();
    auctionListener.JobExecutedHandler += new EventHandler(SendAuctionOrders);
    IMatcher<JobKey> matcher = KeyMatcher<JobKey>.KeyEquals(jobkey);
    _scheduler.ListenerManager.AddJobListener(auctionlistener, matcher);
    // Add to scheduler
    DateTimeOffset ft = _scheduler.ScheduleJob(job, trigger);
    LogEvent(job.Key + " scheduled at: " + ft.ToLocalTime());
    jobkey = new JobKey("Auction2", "G");
    IJobDetail job = JobBuilder.Create<AuctionJob>()
                                .WithIdentity(jobkey)
                                .Build();
    csb = CronScheduleBuilder.CronSchedule(new CronExpression(AuctionTime)).InTimeZone(TimeZoneInfo.Local);
    ICronTrigger trigger = (ICronTrigger)TriggerBuilder.Create()
                                                        .WithIdentity("Auction-Trigger", "G")
                                                        .WithSchedule(csb)
                                                        .Build();
    // Create listener
    JobListener auction2Listener = new JobListener();
    auction2Listener.JobExecutedHandler += new EventHandler(SendAuctionOrders);
    IMatcher<JobKey> matcher = KeyMatcher<JobKey>.KeyEquals(jobkey);
    _scheduler.ListenerManager.AddJobListener(auction2listener, matcher);
    // Add to scheduler
    ft = _scheduler.ScheduleJob(job, trigger);
    LogEvent(job.Key + " scheduled at: " + ft.ToLocalTime());
    _scheduler.Start();
}
void SendAuctionOrders()
{
    // Do something
}

AuctionJob 类如下所示：

public class AuctionJob : IJob
{
    public void Execute(IJobExecutionContext context)
    {
        // Empty
        Console.WriteLine("auction exec");
    }
}

而作业侦听器如下所示：

public class JobListener : IJobListener
{
    private static readonly ILog logger = LogManager.GetLogger(typeof(JobListener));
    public event EventHandler JobExecutedHandler;
    public void JobExecutionVetoed(IJobExecutionContext context)
    {
        logger.Info("JobExecutionVetoed");
    }
    public void JobToBeExecuted(IJobExecutionContext context)
    {
        logger.Info("JobToBeExecuted");
    }
    public void JobWasExecuted(IJobExecutionContext context, JobExecutionException jobException)
    {
        // Raise the event on executed
        OnJobExecuted(EventArgs.Empty);
        logger.Info("JobWasExecuted");
    }
    public string Name
    {
        get
        {
            return "JobListener";
        }
    }
    // Event raiser
    protected virtual void OnJobExecuted(EventArgs args)
    {
        // This code will prevent IllegalThreadContext exceptions
        EventHandler jobExecHandler = JobExecutedHandler;
        if (jobExecHandler != null)
        {
            ISynchronizeInvoke target = jobExecHandler.Target as ISynchronizeInvoke;
            if (target != null && target.InvokeRequired)
            {
                target.Invoke(jobExecHandler, new object[] { this, args });
            }
            else
            {
                jobExecHandler(this, args);
            }
        }
    }
}

触发作业时，作业已执行（控制台打印"拍卖执行"），但作业侦听器的 JobWasExecute 不会选取它。谁能帮我解决这个问题？

其他问题：是否有另一种方法可以调用主窗体的方法？此外，作业侦听器类是否会在整个应用程序中持续存在（理论上不会关闭）。谢谢。
