条件时，终于在一个.NET try..finally块不执行 [英] Conditions when finally does not execute in a .net try..finally block

问题描述

基本上，我听说某些情况下会导致.NET吹过去finally块。有谁知道那些条件？

Basically I've heard that certain conditions will cause .net to blow past the finally block. Does anyone know what those conditions are?

推荐答案

两种可能性：

• <一个href="http://msdn.microsoft.com/en-us/library/system.stackoverflowexception.aspx">StackOverflowException
• <一个href="http://msdn.microsoft.com/en-us/library/system.executionengineexception.aspx">ExecutionEngineException

• StackOverflowException
• ExecutionEngineException

当有finally块将不被执行 StackOverflowException ，因为没有空间在堆栈上，甚至执行更多的code。它还将时候有没有被称为 ExecutionEngineException ，可能出现通过调用 Environment.FailFast（）。

The finally block will not be executed when there's a StackOverflowException since there's no room on the stack to even execute any more code. It will also not be called when there's an ExecutionEngineException, which may arise from a call to Environment.FailFast().
