为什么在控制台执行可以，而写到Global.asax不行？？

[lxiron]

我写了两个定时执行任务的计时器，为什么在控制台是都可以正常执行而，到了Global.asax就不行了呢 ，源代码如；

Global文件里的：

<script runat="server">
    
    void Application_Start(object sender, EventArgs e) 
    {
        // Code that runs on application startup
        //这个计时器可以正常执行
        System.Timers.Timer myTimer = new System.Timers.Timer();
        myTimer.Elapsed += new System.Timers.ElapsedEventHandler(OnTimedEvent);
        myTimer.Interval = 1000;
        myTimer.AutoReset = true;
        myTimer.Enabled = true;
        

        //下面这个线程执行不成功，只能执行一次
        AutoResetEvent autoEvent = new AutoResetEvent(true);
        TimerCallback timerDelegate = new TimerCallback(RequstMyPage);
        System.Threading.Timer startTimer = new System.Threading.Timer(timerDelegate,autoEvent,0,1000*60*3);
    }
    private static void RequstMyPage(object state)
    {
        string url = "http://localhost:4015/ATPSystem/Default.aspx";
        HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url);
        HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
        Stream receiveStream = myHttpWebResponse.GetResponseStream();//得到回写的字节流
        //指定日志文件的目录

        string fileLogPath = AppDomain.CurrentDomain.BaseDirectory + "SystemLogRequst";
        string fileLogName = "SoftPrj_CN_" + DateTime.Now.ToLongDateString() + "_log.txt";
        //定义文件信息对象

        FileInfo finfo = new FileInfo(fileLogPath + fileLogName);

        //创建只写文件流

        using (FileStream fs = finfo.OpenWrite())
        {
            //根据上面创建的文件流创建写数据流

            StreamWriter strwriter = new StreamWriter(fs);
            strwriter.BaseStream.Seek(0, SeekOrigin.End);
            //写入错误发生时间

            strwriter.WriteLine("请求页面发生时间: " + DateTime.Now.ToString());
            //写入日志内容并换行

            //strwriter.WriteLine("错误内容: " + message);

            strwriter.WriteLine("错误内容: ");
            //写入间隔符

            strwriter.WriteLine("---------------------------------------------");
            strwriter.WriteLine();
            //清空缓冲区内容，并把缓冲区内容写入基础流

            strwriter.Flush();
            //关闭写数据流

            strwriter.Close();
            fs.Close();
        }
        
    }
    private static void OnTimedEvent(object source, System.Timers.ElapsedEventArgs e)
    {

        //间隔时间执行某动作
        //指定日志文件的目录
        string fileLogPath = AppDomain.CurrentDomain.BaseDirectory + "SystemLog";
        string fileLogName = "SoftPrj_CN_" + DateTime.Now.ToLongDateString() + "_log.txt";
        //定义文件信息对象
        FileInfo finfo = new FileInfo(fileLogPath + fileLogName);
        //创建只写文件流
        using (FileStream fs = finfo.OpenWrite())
        {
            //根据上面创建的文件流创建写数据流

            StreamWriter strwriter = new StreamWriter(fs);
            strwriter.BaseStream.Seek(0, SeekOrigin.End);
            //写入错误发生时间

            strwriter.WriteLine("定时检查发生时间: " + DateTime.Now.ToString());
            //写入日志内容并换行

            //strwriter.WriteLine("错误内容: " + message);

            strwriter.WriteLine("错误内容: ");
            //写入间隔符

            strwriter.WriteLine("---------------------------------------------");
            strwriter.WriteLine();
            //清空缓冲区内容，并把缓冲区内容写入基础流

            strwriter.Flush();
            //关闭写数据流

            strwriter.Close();
            fs.Close();
        }
   }
</script>

控制台程序两个都可以正常执行

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.Timers;
using System.Threading;
namespace TimerTest
{
    class Program
    {
        private static System.Timers.Timer aTimer;
        static void Main(string[] args)
        {
            aTimer = new System.Timers.Timer(1000);

            aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
            aTimer.AutoReset = true;
            aTimer.Enabled = true;

            AutoResetEvent autoEvent = new AutoResetEvent(false);
            StatusChecker statusChecker = new StatusChecker(10);
            TimerCallback timerDelegate =
                new TimerCallback(statusChecker.CheckStatus);

            Console.WriteLine("{0} Creating timer.\n",
                DateTime.Now.ToString("h:mm:ss.fff"));
            System.Threading.Timer stateTimer =new System.Threading.Timer(timerDelegate, autoEvent, 0, 5000);
            Console.ReadLine();
        }
        private static void OnTimedEvent(object source, ElapsedEventArgs e)
        {
            Console.WriteLine(System.DateTime.Now);
            Console.WriteLine("Time Thread going");
            
        }
    }
    class StatusChecker
    {
        int invokeCount, maxCount;

        public StatusChecker(int count)
        {
            invokeCount = 0;
            maxCount = count;
        }
        public void CheckStatus(Object state)
        {
            Console.WriteLine( DateTime.Now.ToString("h:mm:ss")+"another Theard");
        }
    }
}

帮忙看看怎么回事？

顶一下，看看 啊！

timer在IIS中不行
用线程试一试,thread.sleep(100);

Timer 在IIS里面是可以用的。。。

[wuyq11]

void Application_Start(object sender, EventArgs e)
{
System.Timers.Timer t= new System.Timers.Timer();
t.Interval = 1000;
t.Enabled = true;
}

void Application_End(object sender, EventArgs e)
{
Thread.Sleep(1000);
}
private static void OnTimedEvent(object source, System.Timers.ElapsedEventArgs e)
{}

不明白4楼这样写是什么意思[Quote=引用 4 楼 wuyq11 的回复:]
void Application_Start(object sender, EventArgs e)
    {
        System.Timers.Timer t= new System.Timers.Timer();
      t.Interval = 1000;
      t.Enabled = true;
    }
   
    void Application_End(object sender, EventArgs e)
    {
        Thread.Sleep(1000);
    }
    private static void OnTimedEvent(object source, System.Timers.ElapsedEventArgs e)
    {}

也有可能是配置文件的问题

对于System.Threading.Timer, 在使用的期间必须保持对其的引用，否则会被GC回收。
参见MSDN System.Threading.Timer类的说明
