计时器一般简单

>设置刻度间隔
>向Elapsed事件添加一个处理程序(或者在构建中传递一个回调)，
>如果需要启动定时器(不同的类工作不同)

一切都会好起来的。

样品：

// System.Threading.Timer sample
using System;
using System.Threading;

class Test
{
    static void Main() 
    {
        TimerCallback callback = PerformTimerOperation;
        Timer timer = new Timer(callback);
        timer.Change(TimeSpan.Zero,TimeSpan.FromSeconds(1));
        // Let the timer run for 10 seconds before the main
        // thread exits and the process terminates
        Thread.Sleep(10000);
    }

    static void PerformTimerOperation(object state)
    {
        Console.WriteLine("Timer ticked...");
    }
}

// System.Timers.Timer example
using System;
using System.Threading;
using System.Timers;
// Disambiguate the meaning of "Timer"
using Timer = System.Timers.Timer;

class Test
{
    static void Main() 
    {
        Timer timer = new Timer();
        timer.Elapsed += PerformTimerOperation;
        timer.Interval = TimeSpan.FromSeconds(1).TotalMilliseconds;
        timer.Start();
        // Let the timer run for 10 seconds before the main
        // thread exits and the process terminates
        Thread.Sleep(10000);
    }

    static void PerformTimerOperation(object sender,ElapsedEventArgs e)
    {
        Console.WriteLine("Timer ticked...");
    }
}

我有更多的信息this page，虽然我没有更新很长一段时间。
