如何在Windows服务中设置每日的计时器间隔 [英] how to set timer interval for daily in windows service

问题描述

我创建了用于自动邮件触发的Windows服务，最初我每隔一分钟设置一次计时器间隔，在我的邮件部分工作正常的每一分钟触发已经过去的事件。



但我希望邮件每天都会触发，因为我设定的定时器间隔是1000 * 60 * 60 * 24，但事件没有提出。



以下是代码：



protected override void OnStart（string [] args）

{

TraceService（开始服务）;



//处理已完成事件

计时器。 Elapsed + = new ElapsedEventHandler（OnElapsedTime）;



//此语句用于将间隔设置为1分钟（= 60,000毫秒）

// timer = new System.Timers.Timer（）;

timer.Interval = 1000 * 60 * 60 * 24;



/ /启用计时器

timer.Enabled = true;

timer.AutoReset = true;

timer.Start（）;





}













private void TraceService（字符串内容）

{

//设置文件流

FileStream fs = new FileStream（@d：\ScheduledService.txt，FileMode.OpenOrCreate，FileAccess.Write）;



//设置一个用于添加文本的编写器

StreamWriter sw = new StreamWriter（fs）;



//找到底层文件流的结尾

sw.BaseStream.Seek（0，SeekOrigin.End）;



//添加文本

sw.WriteLine（内容）;



//将文本添加到基础文件流

sw.Flush（）;



//关闭作家

sw.Close（）;

}

I created windows service for auto mail triggering, Initially i set timer interval for every one minute, On elapsed event is triggered for every minute my mail part also working fine.

But i want the mail will trigger every day, for that i set timer interval is 1000*60*60*24, but the event not raised.

Below is the code:

protected override void OnStart(string[] args)
{
TraceService("start service");

//handle Elapsed event
timer.Elapsed += new ElapsedEventHandler(OnElapsedTime);

//This statement is used to set interval to 1 minute (= 60,000 milliseconds)
// timer = new System.Timers.Timer();
timer.Interval = 1000*60*60*24;

//enabling the timer
timer.Enabled = true;
timer.AutoReset = true;
timer.Start();


}






private void TraceService(string content)
{
//set up a filestream
FileStream fs = new FileStream(@"d:\ScheduledService.txt", FileMode.OpenOrCreate, FileAccess.Write);

//set up a streamwriter for adding text
StreamWriter sw = new StreamWriter(fs);

//find the end of the underlying filestream
sw.BaseStream.Seek(0, SeekOrigin.End);

//add the text
sw.WriteLine(content);

//add the text to the underlying filestream
sw.Flush();

//close the writer
sw.Close();
}

尝试使用cron，这是c＃中的一个实现：在C＃中实现一个小型Cron服务 [ ^ ]
