Qrartz.net DailyTimeIntervalScheduleBuilder-如何识别一天中触发器的首次执行和最后执行

Question

在quartz.net触发Execute(IJobExecutionContext context)的一天中尝试标识触发器的首次执行和最后执行。有什么方法可以通过quartz.net Execute(IJobExecutionContext context)方法找到它？

Answer 1

IEnumerable<DateTime> firingTimes = context.Trigger.GetNextFiringTimes(DateTimeOffset.Now.Date, DateTimeOffset.Now.Date.AddDays(1));

public static class TriggerExts
{
    public static IEnumerable<DateTime> GetNextFiringTimes(this ITrigger trigger, DateTimeOffset? after = null, DateTimeOffset? before = null)
    {
        ITrigger temp = trigger.Clone();

        after = after ?? DateTimeOffset.Now;
        DateTimeOffset? next = temp.GetFireTimeAfter(after);
        before = before ?? next.Value.AddYears(1);

        while (next.HasValue && next.Value < before)
        {
            yield return next.Value.LocalDateTime;

            next = temp.GetFireTimeAfter(next.Value);
        }
    }
}
