如何在C＃中使用Tasks.Parallel停止现有任务

Question

我想要做的如下：

1. Start TCP socket listener on another thread (so it does not block my app.)
2. Start 1..n other processes on other threads which will send data to my listener
3. Stop my listener when all of the other processes have finished.

如何使用.Net中的Parallel库实现此目的？

我想我需要以某种方式保留对初始生成线程的引用，并在达到计数器或其他原因时终止它？

使用子级/父级任务怎么办：

从

http://msdn.microsoft.com/en-us/library/dd537609.aspx

var parent = Task.Factory.StartNew(() =>
{
    Console.WriteLine("Parent task beginning.");

    var child = Task.Factory.StartNew(() =>
    {
        Thread.SpinWait(5000000);
        Console.WriteLine("Attached child completed.");
    }, TaskCreationOptions.AttachedToParent);

});

parent.Wait();
Console.WriteLine("Parent task completed.");

/* Output:
    Parent task beginning.
    Attached task completed.
    Parent task completed.
 */

如果您使用异步Socket API，则无需担心为监听的Socket扩展单独的线程...更不用说它围绕性能的同步调用运行了很多时间。

令人回味的食物...
