可以WaitHandle.WaitOne有没有ContextBoundObject类中使用ExitContext标志？ [英] Can WaitHandle.WaitOne with ExitContext flag be used without ContextBoundObject class?

问题描述

MSDN文档表明，有可能使用ExitContext标志的其他方式。请参见 WaitHandle.WaitOne（）其他什么方法是有进入非默认情况下使用ContextBoundObject继承的类之外？ （在我的应用程序无法使用ContextBoundObject）

MSDN documentation suggests that there may be other ways of using ExitContext flag. See WaitHandle.WaitOne() What other ways are there to enter a non-default context outside of using a ContextBoundObject inherited class? (I can't use ContextBoundObject in my application)

推荐答案

线索是这句话。

即使您正在执行   方法一类不获得   自ContextBoundObject，如String，   你可以在非默认情况下，如果   一个ContextBoundObject是在栈   在当前的应​​用程序域。

Even if you are currently executing a method on a class that does not derive from ContextBoundObject, like String, you can be in a nondefault context if a ContextBoundObject is on your stack in the current application domain.

因此​​，基本上，你可以调用的WaitOne 从类中不继承 ContextBoundObject 也不会有任何preconceived概念，即 ContextBoundObject 在涉及您的code任何方式，但有问题的线程可能是在非默认情况下，因为地方的方式在通话堆栈的实例方法 ContextBoundObject 类可以运行不为人知你。

So basically you could call WaitOne from within a class that does not subclass ContextBoundObject nor would you have any preconceived notion that a ContextBoundObject was in any way involved with your code and yet the thread in question could be in a nondefault context because somewhere way up in the call stack an instance method of a ContextBoundObject class could be running unbeknown to you.

这是唯一的例外之外还有进入一个非默认的同步方面没有其他办法。

Outside of that lone exception there are no other ways of entering into a nondefault synchronization context.

有与相关的同步上下文的附加信息穿线pretty的好文章，可找到的这里。

There is a pretty good article on threading with additional information related to synchronization contexts which can be found here.
