在ASP.NET中正确实现后台进程线程 [英] Correctly implement background process Thread in ASP.NET

问题描述

我需要执行一个无限的while循环，并想在global.asax中启动执行. 我的问题是我应该怎么做?我应该启动一个新线程，还是应该使用异步和任务或其他工具?在while循环中，我需要做await 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);

我该怎么做，这样它才不会阻塞任何其他进程，也不会造成内存泄漏?

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

我使用VS10，AsyncCTP3，MVC4

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

只要应用程序可用，我要做的就是将此实例作为全局实例全局运行.

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

已解决

这是Global.asax中的最终解决方案

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)
        {
            signalRConnectionRecovery.Abort();
        }
    }
    catch
    {
            ///
    }
}
