Question

我有问题。我创建了两个Timer对象，一个在每个设定的时间段运行一些方法，第二个对象改变那个时间。问题是：当我尝试从第二个计时器更改第一个计时器的间隔时，我不想在方法更改时运行第一个计时器。

我有以下代码，有人可能会指出我正确的方向吗？

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

namespace ConsoleApplication1
{
    class Program
    {
        public void someFun1(Object obj)
        {
            Console.WriteLine("Start1 " + DateTime.Now);

        }

        public void changeTime1(Object obj)
        {
            someTime1.Change(0, 2000); 
        }

        public static TimerCallback somedel1;
        public static Timer someTime1;

        public static TimerCallback changeTimedel1;
        public static Timer changerTimer1; 

        static void Main(string[] args)
        {
            Program pr = new Program();

            somedel1 = new TimerCallback(pr.someFun1);
            someTime1 = new Timer(somedel1, null, Timeout.Infinite, 10000 );


            changeTimedel1 = new TimerCallback(pr.changeTime1);
            changerTimer1 = new Timer(changeTimedel1, null, 0, 10);


            Console.ReadLine();
        }
    }
}

尝试计算到期时间：

 class Program
    {
        static DateTime _lastInvokation;
        static int somedelInterval = 10000;

        public void someFun1(Object obj)
        {
            Console.WriteLine("Start1 " + DateTime.Now);
            _lastInvokation = DateTime.Now;
        }

        public void changeTime1(Object obj)
        {
            int dueTime = somedelInterval - (int)(DateTime.Now - _lastInvokation).TotalMilliseconds;
            somedelInterval = 2000;
            if (dueTime > 0)
                someTime1.Change(dueTime, somedelInterval);
        }

        public static TimerCallback somedel1;
        public static Timer someTime1;

        public static TimerCallback changeTimedel1;
        public static Timer changerTimer1;

        static void Main(string[] args)
        {
            Program pr = new Program();

            somedel1 = new TimerCallback(pr.someFun1);
            someTime1 = new Timer(somedel1, null, Timeout.Infinite, somedelInterval);
            _lastInvokation = DateTime.Now;

            changeTimedel1 = new TimerCallback(pr.changeTime1);
            changerTimer1 = new Timer(changeTimedel1, null, 0, 10);


            Console.ReadLine();
        }
    }

如何从另一个计时器更改定时线程间隔？
