c# - 使用 Unschedulejob 修改触发器详细信息 - 我做错了什么？ ( quartz 网)

Question

我正在为我正在创建的系统使用 Quartz.NET，其中作业通过 Windows 服务运行，并且可以在 ASP.NET 页面中添加和编辑(包括触发器详细信息)。

不过我遇到了一些问题 - 我需要能够修改触发器的详细信息，例如 simpletrigger 的类型或 cronexpression，并且我被告知我需要取消计划作业然后重新安排它。问题是，取消安排工作然后重新安排是出于某种原因完全从工作中删除触发器。这是我在编辑页面上单击提交按钮时的代码:

 Trigger[] triggers = sched.GetTriggersOfJob(hdnID.Value, hdnGroupID.Value);

        if (ddlScheduleType.SelectedIndex == 1)
        {
            sched.UnscheduleJob(triggers[0].Name, triggers[0].Group);
            foreach (SimpleTrigger trigger in triggers.OfType<SimpleTrigger>())
            {
                if (ddlInterval.SelectedIndex == 0)
                {
                    trigger.RepeatInterval = TimeSpan.Parse("00:00:01");
                }
                else if (ddlInterval.SelectedIndex == 1)
                {
                    trigger.RepeatInterval = TimeSpan.Parse("00:01:00");
                }
                else if (ddlInterval.SelectedIndex == 2)
                {
                    trigger.RepeatInterval = TimeSpan.Parse("01:00:00");
                }


               sched.RescheduleJob(trigger.Name, trigger.Group, trigger);


            }
        }

        else
        {
            foreach (CronTrigger trigger in triggers.OfType<CronTrigger>())
            {
                trigger.CronExpressionString = txtCron.Text;
                sched.UnscheduleJob(triggers[0].Name, triggers[0].Group);
                sched.RescheduleJob(trigger.Name, trigger.Group, trigger);

            }


        }

        sched.AddJob(jobDetail, true);

知道为什么这不起作用吗？谢谢

新:

 if (ddlScheduleType.SelectedIndex == 1)

        {
            foreach (SimpleTrigger trigger in triggers.OfType<SimpleTrigger>())
            {
                Trigger newtrigger = new SimpleTrigger();


                if (ddlInterval.SelectedIndex == 0)
                {
                    newtrigger = TriggerUtils.MakeSecondlyTrigger();
                }
                else if (ddlInterval.SelectedIndex == 1)
                {
                    newtrigger = TriggerUtils.MakeMinutelyTrigger();
                }
                else if (ddlInterval.SelectedIndex == 2)
                {
                    newtrigger = TriggerUtils.MakeHourlyTrigger();
                }

                newtrigger.Name = triggers[0].Name;
                newtrigger.Group = triggers[0].Group;
                newtrigger.JobName = triggers[0].JobName;
                newtrigger.JobGroup = triggers[0].JobGroup;

                sched.RescheduleJob(trigger.Name, trigger.Group, newtrigger);


            }
        }

        else
        {
            foreach (CronTrigger trigger in triggers.OfType<CronTrigger>())
            {
                CronTrigger newtrigger2 = new CronTrigger();
                newtrigger2.Name = trigger.Name;
                newtrigger2.Group = trigger.Group;
                newtrigger2.JobName = trigger.JobName;
                newtrigger2.JobGroup = trigger.JobGroup;

                newtrigger2.CronExpressionString = txtCron.Text;
                sched.RescheduleJob(trigger.Name, trigger.Group, newtrigger2);

            }


        }

• 我怀疑 UnscheduleJob 是否必要。改期应该delete the old trigger , 所以不用它试试

• 您的else 代码没有意义:

      foreach (CronTrigger trigger in triggers.OfType<CronTrigger>())
      {
          trigger.CronExpressionString = txtCron.Text;
          sched.UnscheduleJob(triggers[0].Name, triggers[0].Group);
          sched.RescheduleJob(trigger.Name, trigger.Group, trigger);
      }
  

  你是说也许

      foreach (CronTrigger trigger in triggers.OfType<CronTrigger>())
      {
          trigger.CronExpressionString = txtCron.Text;
          sched.UnscheduleJob(trigger.Name, trigger.Group); //I would remove this 
          sched.RescheduleJob(trigger.Name, trigger.Group, trigger);
      }
  

• 最后，我会尝试使用新触发器而不是修改旧触发器来重新安排
