Task.Delay 的同步上下文 [英] Synchronization context for Task.Delay

问题描述

我发现，Task.Run 总是在来自 .NET Framework 线程池 (TaskScheduler.Default) 的线程上执行.我想，它与 Task.Delay 相同，但我不确定.

I could find out that, Task.Run executes always on threads from .NET Framework threads pool (TaskScheduler.Default). I suppose, that it is the same with Task.Delay, but I'm not sure.

MSDN 表示 Task.Delay 仅:

MSDN says for Task.Delay only:

创建一个将在一段时间延迟后完成的任务

Creates a task that will complete after a time delay

因此问题:Task.Delay在哪里(在哪个同步上下文中)运行?

Therefore the question: Where (in which synchronization context) runs Task.Delay?

推荐答案

Task.Delay 不会在任何地方运行.它只是创建一个在指定时间后完成的任务.与 Task.Run 不同的是，它不接受您的委托在某处运行.大多数任务不会代表在另一个线程上执行某些方法.Task.Run 是执行此操作的少数方法之一.

Task.Delay doesn't run anywhere. It just creates a task that completes after the specified time. Unlike Task.Run it's not accepting a delegate of yours to run somewhere. Most tasks won't represent the execution of some method on another thread. Task.Run is one of few methods that do that.
