正确地在ASP.NET中实现后台进程线程 [英] Correctly implement background process Thread in ASP.NET

问题描述

我需要执行一个无限while循环，并希望发起的Global.asax 执行。
我的问题是我应该究竟如何做到的呢？我应该开始一个新的线程或我应该使用异步和任务或别的什么吗？里面的while循环，我需要做等待TaskEx.Delay（5000）;

I need to execute an infinite while loop and want to initiate the execution in global.asax. My question is how exactly should I do it? Should I start a new Thread or should I use Async and Task or anything else? Inside the while loop I need to do await TaskEx.Delay(5000);

我如何做到这一点，所以它不会阻止任何其他进程，并不会造成内存泄漏？

How do I do this so it will not block any other processes and will not create memory leaks?

的我使用VS10，AsyncCTP3，MVC4 的

编辑：

 public void SignalRConnectionRecovery()
        {
            while (true)
            {
                Clients.SetConnectionTimeStamp(DateTime.UtcNow.ToString());
                await TaskEx.Delay(5000);
            }
        }

所有我需要做的是作为一个单一实例，只要全球的应用可以运行此。

All I need to do is to run this as a singleton instance globally as long as application is available.

编辑：解决

这是在Global.asax中最终解决方案

This is the final solution in Global.asax

protected void Application_Start()
{
    Thread signalRConnectionRecovery = new Thread(SignalRConnectionRecovery);
    signalRConnectionRecovery.IsBackground = true;
    signalRConnectionRecovery.Start();

    Application["SignalRConnectionRecovery"] = signalRConnectionRecovery;
}


protected void Application_End()
{
    try
    {
        Thread signalRConnectionRecovery = (Thread)Application["SignalRConnectionRecovery"];
        if (signalRConnectionRecovery != null && signalRConnectionRecovery.IsAlive == true)
        {
            signalRConnectionRecovery.Abort();
        }
    }
    catch
    {
            ///
    }
}

我发现了有关如何使用异步工人这个漂亮的文章，会试试看。 <一href=\"http://www.dotnetfunda.com/articles/article613-background-processes-in-asp-net-web-applications.aspx\" rel=\"nofollow\">http://www.dotnetfunda.com/articles/article613-background-processes-in-asp-net-web-applications.aspx

I found this nice article about how to use async worker, will give it a try. http://www.dotnetfunda.com/articles/article613-background-processes-in-asp-net-web-applications.aspx
