推荐答案

我写了一个小程序，其中我的调度程序每分钟调用一次显示程序.希望对您有帮助.
显示程序:

I have written small program in which my scheduler program calls display program per minute. I hope it will help you.
Display Program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Timers;

namespace ConsoleApplication3
{
    class Program
    {

        static void Main(string[] args)
        {
             Console.WriteLine(DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss"));
             Console.ReadLine();
        }


    }
}

调度程序

Scheduler Program

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Timers;
namespace ConsoleApplication3
{
    class Scheduler
    {
        System.Timers.Timer processTimer;
        public TimeSpan NextRunTime = TimeSpan.Zero;
        TimeSpan scheduleTime;
        static void Main(string[] args)
        {
            Scheduler obj = new Scheduler();
            obj.SetArchiveProcessScheduleTime();
        }
        private void SetArchiveProcessScheduleTime()
        {
            processTimer = new Timer();
            processTimer.Start();
            
            scheduleTime=TimeSpan.Parse(DateTime.Now.ToString("hh:mm"));
            processTimer.Interval = 100;
            processTimer.Enabled = true;
            processTimer.Elapsed += new ElapsedEventHandler(processTimer_Elapsed);
            while(true)
            {
            }
        }
        private void processTimer_Elapsed(object sender, ElapsedEventArgs e)
        {
            try
            {
                processTimer.Enabled = false;
                //Invoke exe
                System.Diagnostics.Process.Start(@"C:\Pallavi\Test Code\DisplayTime\ConsoleApplication3\bin\Debug\ConsoleApplication3.exe");
                Console.WriteLine("Another process has been invoked: "+DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss"));
                #region Set Next Run Time for Archiving Process
                TimeSpan timeDiff = TimeSpan.Zero;
                NextRunTime = TimeSpan.Zero;
                if (NextRunTime == null || NextRunTime.Equals(TimeSpan.Zero))
                    {
                        NextRunTime = scheduleTime.Add(new TimeSpan(0, 0, 1, 0));//here you can specify whether you want to run per day/hour/minute/second
                        timeDiff = NextRunTime.Subtract(scheduleTime);
                    }
                if (timeDiff.TotalMilliseconds <= 0 || timeDiff.TotalMilliseconds >= Int32.MaxValue)
                    processTimer.Interval = 1000;
                else
                    processTimer.Interval = timeDiff.TotalMilliseconds;
                #endregion Set Next Run Time for Archiving Process
              
                processTimer.Enabled = true;
              
            }
            catch (Exception ex)
            {
              
            }
        }
    }
}
