C#定时job

本文主要是介绍C#定时job，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

工作中经常遇到需要定时处理一些事务，比如定时工单，消息推送。设计思路是建立一套独立的Windows服务来完成，而定时任务的主体，在C#中，有一个Quartz.Net的方法比较容易实现

private static ISchedulerFactory sf = null;
        private static IScheduler sched = null;

        static QuartzManager()
        {
            sf = new StdSchedulerFactory();
            sched = sf.GetScheduler();
            sched.Start();
        }
