Console Example

using System.Threading;
using CronNET;

namespace CronNETExample.Console
{
    class Program
    {
        private static readonly CronDaemon cron_daemon = new CronDaemon();            

        static void Main(string[] args)
        {
            cron_daemon.add_job(new CronJob("* * * * *", task));
            cron_daemon.start();

            // Wait and sleep forever. Let the cron daemon run.
            while(true) Thread.Sleep(6000);
        }

        static void task()
        {
          Console.WriteLine("Hello, world.")
        }
    }
}

Windows Service Example

using System.Threading;
using CronNET;

namespace CronNETExample.WindowsService
{
    public partial class Service : ServiceBase
    {
        private readonly CronDaemon cron_daemon = new CronDaemon();

        public Service()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            cron_daemon.add_job(new CronJob("*/2 * * * *", task));
            cron_daemon.start();
        }

        protected override void OnStop()
        {
            cron_daemon.stop();
        }

        private void task()
        {
          Console.WriteLine("Hello, world.")
        }
    }
}
