一、控制台中使用

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using FluentScheduler;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            //两个参数分别：Job、调度时间
            JobManager.AddJob(() =>
            {
                //任务逻辑
                Console.WriteLine("Timer task,current time:{0}", DateTime.Now);
            }, t =>
            {
                //时间

                //从程序启动开始执行，然后每秒钟执行一次
                t.ToRunNow().AndEvery(1).Seconds();
                ////带有任务名称的任务定时器
                //t.WithName("TimerTask").ToRunOnceAt(DateTime.Now.AddSeconds(5));
            });


            Console.ReadKey();
        }
    }
}

program.cs

二、Web中使用

1、任务逻辑

using System;
using System.Diagnostics;
using System.Threading;
using FluentScheduler;

namespace WebApp.Models
{
    public class MyJob:Registry
    {
        public MyJob()
        {
            // 每2秒一次循环
            Schedule<MyJob1>().ToRunNow().AndEvery(2).Seconds();

            // 5秒后，只一次
            Schedule<MyOtherJob>().ToRunOnceIn(5).Seconds();

            //每天晚上21：15分执行
            Schedule(() => Console.WriteLine("Timed Task - Will run every day at 9:15pm: " + DateTime.Now)).ToRunEvery(1).Days().At(21, 15);

            // 每个月的执行
            Schedule(() =>
            {
                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);
            
            //先执行第一个Job、再执行第二个Job;完成后等5秒继续循环
            Schedule<MyFirstJob>().AndThen<MySecoundJob>().ToRunNow().AndEvery(5).Seconds();
        }
    }

    public class MyJob1 : IJob
    {

        void IJob.Execute()
        {
            Trace.WriteLine("循环每2秒执行一次；现在时间是：" + DateTime.Now);
        }
    }

    public class MyOtherJob : IJob
    {

        void IJob.Execute()
        {
            Trace.WriteLine("5秒后只执行一次 ，现在时间是：" + DateTime.Now);
        }
    }

    public class MyFirstJob : IJob
    {

        void IJob.Execute()
        {
            Trace.WriteLine("执行第一个 Job ，现在时间是：" + DateTime.Now);
        }
    }
    public class MySecoundJob : IJob
    {

        void IJob.Execute()
        {
            Trace.WriteLine("执行第二个 Job ，现在时间是：" + DateTime.Now);
        }
    }


}

MyJob

2、初始化

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;
using FluentScheduler;
using WebApp.Models;

namespace WebApp
{
    public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);

            JobManager.Initialize(new MyJob());
        }
    }
}
