当我使用Quartz.net在特定时间发射我的日常工作时，幻灯片节目无法正常工作

Question

在这里，我给一个小我的代码片段只是为了展示我要实现的目标。

private void frmMain_Load(object sender, EventArgs e)
{
    // construct a scheduler factory
    ISchedulerFactory schedFact = new StdSchedulerFactory();
    // get a scheduler
    sched = schedFact.GetScheduler();
    sched.Start();
    IJobDetail job = JobBuilder.Create<frmMain>()
        .WithIdentity("Job", "group")
        .Build();
    ITrigger trigger = TriggerBuilder.Create()
       .WithDailyTimeIntervalSchedule
         (s =>
            s.WithIntervalInHours(24)
           .OnEveryDay()
           .StartingDailyAt(TimeOfDay.HourAndMinuteOfDay(01, 55))
         )
       .Build();
    sched.ScheduleJob(job, trigger);
}
public void Execute(IJobExecutionContext context)
{
    generate();
}
public void generate()
{
    if (this.FetchStart != null)
        this.FetchStart(this, new EventArgs());
    System.Threading.Thread.Sleep(5000);
    if (this.FetchDone != null)
        this.FetchDone(this, new EventArgs());
}

我已经完成了VS2013社区版的项目。我的目标是每天在特定时间致电幻灯片节目例程。当我在没有Quartz.net调度程序的情况下调用幻灯片显示例程时，它可以正常工作，但是当我通过Quartz.net调度程序调用例程时，请调用例程，但是没有幻灯片显示图像显示。

>

我尚不清楚发生什么问题。根据我的目标，我必须使用Quartz.net调度程序，因为我需要每天在一天的特定时间调用我的日常工作。

在这里，我正在共享我的项目代码，因为它在OneDrive中。因此，我的要求请有人下载我的项目，并在您的尽头跑步以查看问题，并告诉我原因导致不在图片框中显示图像的原因。

如果可能的话，请使用Quartz.net调度程序代码纠正我的代码。一个驱动器项目链接是https://1drv.ms/f/s！mifmnv-codpa81zfinh6ur7qro

我上传了项目文件夹。

谢谢

更新

当我将背景工人与Quartz.net一起使用我的生成例程时，我也找不到改进。幻灯片显示图像没有出现在图片框上。

这是带有背景工人的Quartz.net的代码

            // The background process is complete. We need to inspect
            // our response to see if an error occurred, a cancel was

Answer 1

花了很多小时后，我找到了获得代码工作的方法。

我必须以这种方式通过我的表格参考。

    ISchedulerFactory schedFact = new StdSchedulerFactory();
    // get a scheduler
    sched = schedFact.GetScheduler();
    sched.Start();
    IJobDetail job = JobBuilder.Create<frmMain>()
        .WithIdentity("Job", "group")
        .Build();
    job.JobDataMap.Put("Form", this);
    ITrigger trigger = TriggerBuilder.Create()
       .WithDailyTimeIntervalSchedule
         (s =>
            s.WithIntervalInHours(24)
           .OnEveryDay()
           .StartingDailyAt(TimeOfDay.HourAndMinuteOfDay(20, 27))
         )
       .Build();
    sched.ScheduleJob(job, trigger);

主要技巧在这里

job.JobDataMap.Put("Form", this);

和

public void Execute(IJobExecutionContext context)
{
    var dataMap = context.MergedJobDataMap;
    var frmInstance = (frmMain) dataMap["Form"];
    frmInstance.generate();
}
