如何在一天结束时自动重置计时器，如何显示上次执行的时间和日期？该计划是 -

namespace Time_Writer
{
    class Program
    {
        static int count = 1;
        static double seconds;
        static int total = 10000;
        private static System.Timers.Timer aTimer;

        static void Main(string[] args)
        {
            ReadCountFromFile();

            aTimer = new System.Timers.Timer();
            aTimer.Elapsed +=new System.Timers.ElapsedEventHandler(aTimer_Elapsed);
            aTimer.Interval = 5000;
            aTimer.Enabled = true;
            Console.WriteLine("Press Enter To Exit The Program\n");
            Console.ReadLine();
            AppDomain.CurrentDomain.ProcessExit += new EventHandler(CurrentDomain_ProcessExit);

        }
        private static void ReadCountFromFile()
        {
            try
            {
                if (File.Exists(".\\mynumber.dat"))
                {
                    using (var file = File.Open(".\\mynumber.dat", FileMode.Open))
                    {
                        byte[] bytes = new byte[4];
                        file.Read(bytes, 0, 4);
                        count = BitConverter.ToInt32(bytes, 0);
                        total = total - count;
                        Console.WriteLine("Total count left is = {0}", total);
                        Console.WriteLine("Limit = 10000");
                        Console.WriteLine("Count  = {0}", count);

                    }
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine("Problem reading file.");
            }
        }
        static void CurrentDomain_ProcessExit(Object sender, EventArgs e)
        {
            using (var file = File.Open(".\\mynumber.dat", FileMode.OpenOrCreate))
            {
                var buffer = BitConverter.GetBytes(count);
                file.Write(buffer, 0, buffer.Length);
            }
        }
        private static void aTimer_Elapsed(object source, ElapsedEventArgs e)
        {
            Console.WriteLine("Name is Yap {0}", e.SignalTime);
            seconds += 5;
            count += 1;
            if (count>10000 || seconds == 86400)
            {
                aTimer.Enabled = false;
                Console.WriteLine("\n\nTimer is off at {0}\n\n", e.SignalTime.TimeOfDay.ToString());

            }
        }
    }
}

我修改你的代码并将你的计时器包装成一个线程。我减少了计时器和计数，使其更容易测试。我确信有一个更好的方法来编码它，但这个解决方案似乎有效。你可能需要根据需要调整线程睡眠。

您可以通过播放条件

来调整进程何时停止和重新启动

if (count > TOTAL || _processStart.AddSeconds(1) < DateTime.Now) )

在函数aTimer_Elapsed中。

如果流程运行超过1秒或计数已到达，则重新启动流程。

class Program
{

    private static DateTime _processStart;
    static int count = 1;
    const int TOTAL = 15;
    private static Timer aTimer;

    private static Thread _process;

    static void Main(string[] args)
    {
        _process = new Thread(DoProcess);
        _process.Start();
        Console.WriteLine("Press Enter To Exit The Program\n");
        Console.ReadLine();
        ProcessExit();
    }

    static void DoProcess()
    {
        _processStart = DateTime.Now;
        ReadCountFromFile();

        if (count < TOTAL)
        {
            Console.WriteLine("******START TIMER******");
            aTimer = new Timer();
            aTimer.Elapsed += aTimer_Elapsed;
            aTimer.Interval = 500;
            aTimer.Enabled = true;
            while (aTimer.Enabled)
            {
                Thread.Sleep(1000);
            }
            Console.WriteLine("******END TIMER******");
            ProcessExit();
            DoProcess();
        }
    }

    private static void ReadCountFromFile()
    {
        try
        {
            if (File.Exists(".\\mynumber.dat"))
            {
                using (var file = File.Open(".\\mynumber.dat", FileMode.Open))
                {
                    byte[] bytes = new byte[4];
                    file.Read(bytes, 0, 4);
                    count = BitConverter.ToInt32(bytes, 0);
                    Console.WriteLine("Total count left is = {0} / Limit = {1} / Count  = {2}", TOTAL - count, TOTAL, count);

                }
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("Problem reading file.");
        }
    }

    static void ProcessExit()
    {
        using (var file = File.Open(".\\mynumber.dat", FileMode.OpenOrCreate))
        {
            var buffer = BitConverter.GetBytes(count);
            file.Write(buffer, 0, buffer.Length);
        }
    }

    private static void aTimer_Elapsed(object source, ElapsedEventArgs e)
    {
        //Console.WriteLine("Name is Yap {0}", e.SignalTime);
        if (count < TOTAL)
        {
            count += 1;
            Console.WriteLine("Count is {0}", count);
        }
        if (count > TOTAL || _processStart.AddSeconds(1) < DateTime.Now) 
        {
            aTimer.Enabled = false;
            Console.WriteLine("Timer is off at {0} count is {1}", e.SignalTime.TimeOfDay.ToString(),count);
        }
    }
}
