如何检查特定作业是否在quartz调度程序中运行#

我正在使用石英调度程序根据触发器的用户输入来安排写入文件的作业。我想检查作业是否仍在 stop() 方法中运行。如何检查作业是否仍在运行？

 public class JobScheduler
{
    static StdSchedulerFactory schedulerFactory = new StdSchedulerFactory();
    public IScheduler scheduler = schedulerFactory.GetScheduler().Result;
    public void start()
    {
        scheduler.Start();

        IJobDetail jobDetail = JobBuilder.Create<FileWritingJob>().WithIdentity("FileWriteJob","FileWriteGroup").Build();

        string date_time = System.Configuration.ConfigurationManager.AppSettings["datetime"];
        System.Diagnostics.Debug.WriteLine(date_time);
        DateTime dateTime = DateTime.Parse(date_time);
        System.Diagnostics.Debug.WriteLine("Parse datetime:"+dateTime);
        string frequency= System.Configuration.ConfigurationManager.AppSettings["frequency"];
        System.Diagnostics.Debug.WriteLine("Frequency:" + frequency);
        if (frequency.Equals("hourly", StringComparison.InvariantCultureIgnoreCase) && !frequency.Equals("default"))
        {
            ITrigger hourlyTrigger = TriggerBuilder.Create().WithIdentity("hourlyTrigger").WithCronSchedule("0 " + dateTime.Minute + " " + dateTime.Hour + "/1 1/1 * ? *").StartAt(DateBuilder.DateOf(dateTime.Hour, dateTime.Minute, dateTime.Second, dateTime.Day, dateTime.Month, dateTime.Year)).Build();
            scheduler.ScheduleJob(jobDetail, hourlyTrigger);
        }
        else if (frequency.Equals("daily", StringComparison.InvariantCultureIgnoreCase) && !frequency.Equals("default"))
        {
            ITrigger dailyTrigger = TriggerBuilder.Create().WithIdentity("dailyTrigger").WithCronSchedule("0 " + dateTime.Minute + " " + dateTime.Hour + " 1/1 * ? *").StartAt(DateBuilder.DateOf(dateTime.Hour, dateTime.Minute, dateTime.Second, dateTime.Day, dateTime.Month, dateTime.Year)).Build();
            scheduler.ScheduleJob(jobDetail, dailyTrigger);
        }
        else if (frequency.Equals("weekly", StringComparison.InvariantCultureIgnoreCase) && !frequency.Equals("default"))
        {
            ITrigger weeklyTrigger = TriggerBuilder.Create().WithIdentity("weeklyTrigger").WithCronSchedule("0 " + dateTime.Minute + " " + dateTime.Hour + " 1/7 * ? *").StartAt(DateBuilder.DateOf(dateTime.Hour, dateTime.Minute, dateTime.Second, dateTime.Day, dateTime.Month, dateTime.Year)).Build();
            scheduler.ScheduleJob(jobDetail, weeklyTrigger);
        }

    }
    public void stop()
    {
        scheduler.Shutdown().ConfigureAwait(false).GetAwaiter().GetResult();
    }
}

在 Quartz 2.x 中，您可以从调度程序获取所有正在执行的作业，我没有用 3.x 对其进行测试，但我确信它是相同的。

var executingJobs = scheduler.GetCurrentlyExecutingJobs();
