拦截里面IDisposable.Dispose异常 [英] Intercepting an exception inside IDisposable.Dispose

问题描述

在 IDisposable.Dispose 方法是有办法弄清楚，如果一个异常被抛出？

In the IDisposable.Dispose method is there a way to figure out if an exception is being thrown?

using (MyWrapper wrapper = new MyWrapper())
{
    throw new Exception("Bad error.");
}

如果抛出一个异常，在使用发言中，我想知道这件事情的时候的IDisposable 对象设置

If an exception is thrown in the using statement I want to know about it when the IDisposable object is disposed.

推荐答案

否，有没有办法做到这一点，在.NET框架中，则无法计算出电流异常，而─是 - 被抛出的最后条款。

No, there is no way to do this in the .Net framework, you cannot figure out the current-exception-which-is-being-thrown in a finally clause.

请参阅此职位上我的博客，与在类似的模式比较红宝石，它突出我觉得差距与IDisposable模式存在。

See this post on my blog, for a comparison with a similar pattern in Ruby, it highlights the gaps I think exist with the IDisposable pattern.

Ayende有一个绝招，让你<一个href="http://ayende.com/Blog/archive/2007/06/20/Did-you-know-Find-out-if-an-exception-was-thrown.aspx">detect异常发生的，但是，它不会告诉你这是其中的例外。

Ayende has a trick that will allow you to detect an exception happened, however, it will not tell you which exception it was.
