我应该取代我所有的"新的Thread"与" Task.Factory.StartNew"？ [英] Should I replace all my "new Thread" with "Task.Factory.StartNew"?

问题描述

我读过有关任务之间的不同（系统任务的优点.Threading.Task）和线程

此外MSDN说：......在.NET Framework 4中，任务是编写多的首选API 。线程，异步和并行代码

Also msdn says that "...in the .NET Framework 4, tasks are the preferred API for writing multi-threaded, asynchronous, and parallel code."

现在我的程序包含从UDP接收组播数据这样的代码：

Now my program contains such code which receive multicast data from udp:

thread = new Thread(WhileTrueFunctionToReceiveDataFromUdp);
.....
thread.Start();

我有好几个这样的线程每个插座。
我是更好的替代这段代码使用任务？

推荐答案

这取决于你在做什么 - 如果你不打算使用的任何新功能工作和TPL，和您现有的代码工作， 。没有理由改变。

It depends on what you're doing - if you're not going to use any of the new features in Task and the TPL, and your existing code works, there's no reason to change.

然而，工作有许多优点 - 特别是要运行操作一个线程池线程并返回结果。

However, Task has many advantages - especially for operations that you want to run in a thread pool thread and return a result.

另外 - 因为你使用线程每个插座，则可能需要更长的使用寿命线程。因此，如果你切换到 Task.Factory.StartNew ，你可能要指定的任务应该是的 LongRunning 否则你会风使用大量线程池线程的套接字的数据（用默认的调度）。

Also - given that you're using "threads for each socket", you likely will have longer life threads. As such, if you do switch to Task.Factory.StartNew, you'll potentially want to specify that the tasks should be LongRunning or you'll wind up using a lot of ThreadPool threads for your socket data (with the default scheduler).
