更换任务调度程序在C＃中使用一个定制了一辆 [英] Replacing the task scheduler in C# with a custom-built one

问题描述

我在想，如果我可以改变任务调度程序映射使用C＃任务在.NET中真正的操作系统线程，或者如果我需要重新编译，比方说，在Mono运行时做到这一点。谢谢你。

I was wondering if I can change the task scheduler that maps tasks to the real OS threads in .NET using C#, or if I need to recompile, say, the Mono runtime to do this. Thanks.

推荐答案

如果你指的 System.Threading.Tasks 那么，你需要的是子类的TaskScheduler 然后你可以使用你的类的对象初始化 TaskFactory 。有一个例如的MSDN研究。我还发现了一个的例如，在博客PSY codeDeveloper 。

System.Threading.Tasks

If you refer to System.Threading.Tasks then what you need is to subclass TaskScheduler and then you can use an object of your class to initialize a TaskFactory. There is an example in MSDN. I have also found an example in the blog psyCodeDeveloper.

除此之外，您可以使用的SynchronizationContext 以处理方法发布到线程池（与线程池的任务。 QueueUserWorkItem 为例）得到处理。

Aside from that you could use SynchronizationContext to handle the way the tasks posted to the ThreadPool (with ThreadPool.QueueUserWorkItem for example) get handled.

有关，你可能会感兴趣的一系列理解的SynchronizationContext在$ C $的CProject（的第1部分，部分2 和部分3 ）。

For that you may be interested in the series Understanding SynchronizationContext at CodeProject (part 1, part 2 and part 3).

至于在无扩展的自定义调度，您还可以使用的SynchronizationContext上面提到的，有关详细信息，查看教程在 introtorx.com 特别第4部分：并发

As for the custom schedulers in Reactive Extensions, you can also use the SynchronizationContext mentioned above, for more information check the tutorial at introtorx.com in particular Part 4: Concurrency.

当然，你可以滚自己线程池，但这样做是不明智的。除此之外，你可以手动处理您的线程 - 老办法

Of course you can roll your own thread pool, although doing that is not advised. Aside from that you could handle your threads manually - the old way.

其他的方法来处理任务，包括调度计时器，并有专门的线程做的工作。

Other approaches to handle tasks include scheduling with timers and having dedicated threads to do the work.

As part of the Theraot Libraries you will find the class Work which is based on a lock free queue and can be configured to have any number of dedicated threads, also threads waiting on tasks contribute their time to execute tasks, any extra work is delegated to the ThreadPool. This is part of an ongoing effort to backport System.Threading.Tasks to .NET 2.0.

在 Theraot图书馆工作类离开我们已经有一段时间了，的部分回港 System.Threading.Tasks 的.NET 2.0可与自定义的TaskScheduler支持。

In Theraot Libraries the Work class has been gone for a while now, a partial back port of System.Threading.Tasks for .NET 2.0 is available with support for custom TaskScheduler.
