1.安装Quartz包

2.编写Job任务

继承 IJob编辑自定义任务

3.调用job，以指定时间策略执行

定时600s执行一次

StdSchedulerFactory factory = new StdSchedulerFactory();
IScheduler scheduler = await factory.GetScheduler();
await scheduler.Start();

// 定义一个作业并关联触发器
IJobDetail job = JobBuilder.Create<SmsReportJob>()
    .WithIdentity("smsReport", "group1")
    .Build();

ITrigger trigger = TriggerBuilder.Create()
            .WithIdentity("trigger1", "group1")
            .WithSimpleSchedule(x => x.WithIntervalInSeconds(600).RepeatForever())
            .Build();

await scheduler.ScheduleJob(job, trigger);

如果只执行一次的话这样即可

var trigger = TriggerBuilder.Create()
                .WithSimpleSchedule(x => x.WithIntervalInSeconds(5).WithRepeatCount(0))
                .Build();
