第一步：Install-Package Quartz

namespace ProjectEdb

{

    class Program

    {

        static void Main(string[] args)

        {

           //例子1

            QuartzJob.CreateJob("test", "zkb", "0 */1 * * * ?").GetAwaiter().GetResult();

            //例子2

            //RunProgram().GetAwaiter().GetResult();

        }

    }

}

{

  public  class QuartzJob

    {

        public static async Task CreateJob(string name, string group, string cron)

        {

            ISchedulerFactory schedulerFactory = new StdSchedulerFactory();

            IScheduler scheduler = await schedulerFactory.GetScheduler();

            DateTimeOffset startTime = DateBuilder.NextGivenSecondDate(DateTime.Now, );

            DateTimeOffset endTime = DateBuilder.NextGivenMinuteDate(DateTime.Now, );

            IJobDetail job = JobBuilder.Create<EdbQuartz>()

                             .WithIdentity(name, group)

                             .Build();

            ICronTrigger cronTrigger = (ICronTrigger)TriggerBuilder.Create()

                                       .StartAt(startTime)

                                       .EndAt(endTime)

                                       .WithIdentity(name, group)

                                       .WithCronSchedule(cron)

            await scheduler.ScheduleJob(job, cronTrigger);

            await scheduler.Start();

            Console.ReadLine();//这句话在net core控制台应用程序里是一定要加上的，否则，控制台的输出框会闪一下就没了

        }
