  • 三分钟掌握,使用Quqrtz.Net实现定时发送邮件

    在实际的项目中,常遇到延时触发工作以及定时触发工作

    这里所讲的是借助第三方的组件 Quartz.Net 来实现(源码位置:https://github.com/quartznet/quartznet)

    实现思路(来自博友wuzh)

    一:继承并实现IJob接口,在Execute 方法中写你要定时执行的事情(切记 )

    二:使用Quartz创建任务调度核心代码步骤

      1、配置Quartz,创建工厂,开启调度。

      2、创建工作任务

      3、创建触发器

      4、将任务加入到任务池

    Demo 创建控制台应用程序,定时发送邮件以及延时写日志

    1 在vs2015中使用Nuget,获取Quartz

     2 创建两个作业

        /// <summary>

                    using (StreamWriter writer = new StreamWriter(fileName, true))
                    {
                        task = writer.WriteLineAsync(string.Format("{0},测试", DateTime.Now.ToLongTimeString()));
                        Console.WriteLine(string.Format("{0},测试", DateTime.Now.ToLongTimeString()));
                    }
