写在前面

FluentScheduler是.Net平台下的一个自动任务调度组件，以前经常用的是Quarz.Net，相对而言FluentScheduler的定时配置更为直观，可直接用接口进行参数化设置，对Cron表达式有恐惧症的人来说简直就是福音，使用起来非常方便。

老规矩从NuGet获取该组件

代码实现

    public class SchedulerTester{public static void TestAddJob(){JobManager.Initialize();JobManager.AddJob(() => Console.WriteLine("1 minutes just passed."),s => s.ToRunEvery(1).Minutes());}public static void TestUseRegistry(){var registry = new Registry();registry.Schedule<MyJob>().ToRunNow().AndEvery(2).Seconds();registry.Schedule<MyJob>().ToRunOnceIn(5).Seconds();registry.Schedule(() => Console.WriteLine("It's 9:15 PM now.")).ToRunEvery(1).Days().At(21, 15);//registry.Schedule<MyComplexJob>().ToRunNow().AndEvery(1).Months().OnTheFirst(DayOfWeek.Monday).At(3, 0);registry.Schedule<MyComplexJob>().ToRunNow().AndEvery(1).Seconds();registry.Schedule<MyJob>().AndThen<MyOtherJob>().ToRunNow().AndEvery(5).Minutes();JobManager.Initialize(registry);}public static void TestMyRegistry(){JobManager.Initialize(new MyRegistry());}}public class MyRegistry : Registry{public MyRegistry(){// Schedule an ITask to run at an intervalSchedule<MyJob>().ToRunNow().AndEvery(2).Seconds();// Schedule an ITask to run once, delayed by a specific time interval. Schedule<MyJob>().ToRunOnceIn(5).Seconds();// Schedule a simple task to run at a specific timeSchedule(() => Console.WriteLine("Timed Task - Will run every day at 9:15pm: " + DateTime.Now)).ToRunEvery(1).Days().At(21, 15);// Schedule a more complex action to run immediately and on an monthly intervalSchedule(() =>{Console.WriteLine("Complex Action Task Starts: " + DateTime.Now);Thread.Sleep(1000);Console.WriteLine("Complex Action Task Ends: " + DateTime.Now);}).ToRunNow().AndEvery(1).Months().OnTheFirst(DayOfWeek.Monday).At(3, 0);// Schedule a job using a factory method and pass parameters to the constructor.Schedule(() => new MyComplexJob("Foo", DateTime.Now)).ToRunNow().AndEvery(2).Seconds();//Schedule multiple tasks to be run in a single scheduleSchedule<MyJob>().AndThen<MyOtherJob>().ToRunNow().AndEvery(1).Minutes();}}public class MyJob : IJob{public void Execute(){Console.WriteLine("MyJob is Executed");}}public class MyOtherJob : IJob{public void Execute(){Console.WriteLine("MyOtherJob is Executed");}}public class MyComplexJob : IJob{private string _name { get; set; }private DateTime _date { get; set; }public MyComplexJob(string name, DateTime dateTime){this._name = name;this._date = dateTime;}public void Execute(){Console.WriteLine($"MyComplexJob is Executed, name is {_name}, datetime:{_date.ToShortDateString()}");}}

调用示例：

SchedulerTester.TestUseRegistry();SchedulerTester.TestMyRegistry();SchedulerTester.TestAddJob();

执行结果
