C# Timer类

C# 有三种不同的Timer类

1.Threading.Timer

2.Timer.Timer

3.Forms.Timer

 

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

namespace TimerTest
{
    class Program
    {
        public static Timer timer1 = new Timer(new TimerCallback(timer1Callback), null, 50, 50);
        public Timer timer2 = new Timer(new TimerCallback(timer2Callback), null, 50, 50);
        static void Main(string[] args)
        {
            Thread.CurrentThread.Name = "MainThread";

            Program p = new Program();
            Program.timer1.Change(0,50);
            p.timer2.Change(0, 50);
            p.timer2.Change(0, Timeout.Infinite);
            Console.ReadKey();
        }


        public static void timer2Callback(object o)
        {
            Thread.CurrentThread.Name = "Timer2";
            Console.WriteLine(Thread.CurrentThread.Name + " is running ! Time: " + DateTime.Now + "timer2Callback called!");
        }

        public static void timer1Callback(object o)
        {
            Thread.CurrentThread.Name = "Timer1";
            Console.WriteLine(Thread.CurrentThread.Name+ " is running ! Time: "+ DateTime.Now +"timer1Callback called!");
        }
    }
}

１。不保证每个timer对应的线程间的同步。每隔一断区间打开一个线程来执行timercallback里的操作。

２。就算把时间区间写成１也还是要等到５５毫秒才会执行下一个timer。
