本文介绍了TaskCreationOptions.LongRunning 选项和 ThreadPool的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

TPL 使用任务调度器来协调任务.根据官方文档，默认任务调度器使用线程池，但如果TaskCreationOptions.LongRunning 选项，然后它将为该任务(A)创建一个专用线程.

TPL uses Task Schedulers to coordinate tasks. According to official document, default task scheduler uses Thread Pool, but if TaskCreationOptions.LongRunning option is presented then it will create a dedicated thread for that task (A).

问题:截至目前，Visual Studio 2010 的 MSDN 文档尚未准备好，当前在线 MSDN 尚未最终确定；有谁知道(A)是对还是错?

Question: As of now MSDN documents for Visual Studio 2010 are not ready and current online MSDN is not finalized; does anyone knows if (A) is true or false?

推荐答案

是的，LongRunning 强制在池外创建新线程.下面是来自最新框架版本的一些伪反汇编代码:

Yes, LongRunning forces the creation of a new thread outside the pool. Here's some pseudo-disassembled code from the latest framework version:

...
if (task.Options HasFlag LongRunning) then
    create new Thread thread
    thread.Start(task)
...

从丑陋的 C# 转换为伪代码.
