使用LINQ查询/子查询多个方法(Quartz.NET示例用于组,作业和触发器)

using Quartz;
using Quartz.Impl;
using System.Linq;

// 创建调度器
IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler();

// 创建作业和触发器
IJobDetail job = JobBuilder.Create<MyJob>()
    .WithIdentity("myJob", "myGroup")
    .Build();
ITrigger trigger = TriggerBuilder.Create()
    .WithIdentity("myTrigger", "myGroup")
    .StartNow()
    .WithSimpleSchedule(x => x.WithIntervalInSeconds(10).RepeatForever())
    .Build();

// 将作业和触发器添加到调度器
await scheduler.ScheduleJob(job, trigger);

// 使用LINQ查询作业
var jobs = (await scheduler.GetJobKeys(GroupMatcher<JobKey>.GroupEquals("myGroup")))
    .Select(jobKey => scheduler.GetJobDetail(jobKey))
    .ToList();

// 使用LINQ查询触发器
var triggers = (await scheduler.GetTriggerKeys(GroupMatcher<TriggerKey>.GroupEquals("myGroup")))
    .Select(triggerKey => scheduler.GetTrigger(triggerKey))
    .ToList();

// 使用LINQ查询作业和触发器
var jobTriggers = jobs.Select(job => new { Job = job, Trigger = triggers.FirstOrDefault(trigger => trigger.JobKey.Equals(job.Key)) })
    .Where(x => x.Trigger != null)
    .ToList();

// 删除作业和触发器
foreach (var jobTrigger in jobTriggers)
{
    await scheduler.UnscheduleJob(jobTrigger.Trigger.Key);
    await scheduler.DeleteJob(jobTrigger.Job.Key);
}
