不要等待长时间运行的操作 ASP.NET MVC
当用户执行某些操作（生成多个报告）时，我们会触发一些长时间运行的操作。我们不希望用户等到这些报告生成。有没有一种无需实施作业调度程序即可快速完成此任务的方法？也许使用这样的线程？或者这不安全？
public ActionResult About()
{
Thread thread = new Thread(new ThreadStart(MuchWork));
thread.Start();
return View();
}
public void MuchWork()
{
Thread.Sleep(10000);
Thread.Sleep(4000);
}
We have some long running operation firing when the user does something(generating several reports). We don't want the user to wait till those reports have been generated. Is there a quick way to accomplish this without having to implement a jobscheduler? Maybe using threads like this? Or is this not safe?
public ActionResult About()
{
Thread thread = new Thread(new ThreadStart(MuchWork));
thread.Start();
return View();
}
public void MuchWork()
{
Thread.Sleep(10000);
Thread.Sleep(4000);
}

请参阅帖子 The Dangers of Implementing Recurring Back Tasks In ASP.NET by Phil Haack，其中描述了如何在使用 IRegisteredObject 接口 限制 IIS/AppPool 关闭问题。

这是不安全的。您的服务器在操作过程中崩溃了怎么办？并且用户不知道该操作从未被执行。
一般来说，工作流/持久机制会对此有所帮助，但您必须真正考虑灾难性场景的业务/用户体验案例。
It is not safe. What about your server crashing during the operation? And the user not knowing the operation never was performed.
In general, a workflow / persistent mechanism would help with that, but you have to really think about your business / user experience case for catastrphic scenarios here.
也许使用线程池或 TPL，这样您就可以检查状态并且不会被线程滥用？
我所说的“检查”是指在旋转另一个请求之前查看您已经运行了多少个请求。
我猜测操作的结果被写入某个数据库表中，以便用户可以轮询并查看状态？
maybe use the threadpool, or TPL so you can check status and not get thread-abused?
by 'check' i mean see how many of these requests you already have running before spinning another one.
im geussing that the result of the operation is written in some DB table , so the user can poll and see the status ?
