后台工作者阻止 MVC 控制器操作

我想在新线程/异步中从 ASP.NET MVC 控制器操作运行一些代码。我不关心响应，我想在异步方法在后台运行时触发并忘记并向用户返回一个视图。我认为 BackgroundWorker 类适合这个？

public ActionResult MyAction()
{
    var backgroundWorker = new BackgroundWorker();
    backgroundWorker.DoWork += Foo;
    backgroundWorker.RunWorkerAsync();

    return View("Thankyou");
}

void Foo(object sender, DoWorkEventArgs e)
{
    Thread.Sleep(10000);
}

为什么这段代码会导致返回视图之前有 10 秒的延迟？为什么视图没有立即返回？

更重要的是，我需要做什么才能使这项工作成功？

谢谢

I want to run some code from an ASP.NET MVC controller action in a new thread/asynchronously. I don't care about the response, I want to fire and forget and return the user a view while the async method runs in the background. I thought the BackgroundWorker class was appropriate for this?

public ActionResult MyAction()
{
    var backgroundWorker = new BackgroundWorker();
    backgroundWorker.DoWork += Foo;
    backgroundWorker.RunWorkerAsync();

    return View("Thankyou");
}

void Foo(object sender, DoWorkEventArgs e)
{
    Thread.Sleep(10000);
}

Why does this code cause there to be a 10 second delay before returning the View? Why isnt the View returned instantly?

More to the point, what do I need to do to make this work?

Thanks

您可以开始新线程：

public ActionResult MyAction()
{
    var workingThread = new Thread(Foo);
    workingThread.Start();

    return View("Thankyou");
}

void Foo()
{
    Thread.Sleep(10000);
}

You can just start new thread:

public ActionResult MyAction()
{
    var workingThread = new Thread(Foo);
    workingThread.Start();

    return View("Thankyou");
}

void Foo()
{
    Thread.Sleep(10000);
}
