我正在将 Quartz.NET 用于我正在创建的系统，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 或 cronexpression 的类型，并且我被告知我需要取消安排作业然后重新安排它。问题是，由于某种原因，取消计划工作然后重新计划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);

任何想法为什么这不起作用？谢谢

 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 是必要的。重新安排应该删除旧的触发器，所以尝试不使用它

  • 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，我会尝试使用新的触发器而不是修改旧的触发器来重新安排
