最好的方法＆QUOT;块QUOT;直到某些条件得到满足 [英] Best method to "block" until certain condition is met

问题描述

我想创造一些方法，以通用的方式来使用，是它会阻止（除非某个超时），直到给定的条件得到满足。

I would like to create some method to be used in a generic way, were it would block (unless a certain timeout expires) until a given condition is met.

在code中的使用将是类似于：

The usage in code would be something similar to:

WaitUntil( condition );

我已经尝试过使用一段时间（..）循环实现它，但是这似乎是一种浪费。

I have tried implementing it using a While ( .. ) loop, however this seems like a waste.

在当前实现，我初始化一次性计时器在超时到期。我运行一个while循环，并检查是否定时器超时与否，如果它没有抛出异常。

In current implementation, i am initializing a 'one-off' timer that expires at TIMEOUT. I am running a while loop, and checking if the timer has timed out or not, throwing an exception if it did.

有没有简单而有效的技术来实现这样的方法？

Are there any simple yet effective techniques for implementing such a method ?

推荐答案

看一看阿尔巴哈利的线程文章，特别是基本同步部分和<一href="http://msdn.microsoft.com/en-us/library/system.threading.manualresetevent.aspx">ManualResetEvent和<一href="http://msdn.microsoft.com/en-us/library/system.threading.autoresetevent.aspx">AutoResetEvent.这会给你有关.NET中的信令结构是个好主意。

Have a look at Albahari's threading article, especially the basic synchronization part and the ManualResetEvent and AutoResetEvent. This will give you a good idea about signalling constructs in .NET.
