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。
