使用C#的Timer控件来实现定时触发事件，其主要参数如下：
Timer.Enabled 属性用于设置是否启用定时器
Timer.Interval 属性，事件的间隔，单位毫秒
Timer.Elapsed 事件，达到间隔时发生
示例：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Timers;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
System.Timers.Timer aTimer = new System.Timers.Timer();
aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
// Set the Interval to 5 seconds.
aTimer.Interval = 5000;
aTimer.Enabled = true;
Console.WriteLine("Press \'q\' to quit the sample.");
while (Console.Read() != 'q') ;
}
private static void OnTimedEvent(object source, ElapsedEventArgs e)
{
Console.WriteLine("Hello World!");
}
}
}
