当 finally 不在 .net try..finally 块中执行时的条件

Conditions when finally does not execute in a .net try..finally block(当 finally 不在 .net try..finally 块中执行时的条件)

问题描述

基本上我听说某些条件会导致 .net 吹过 finally 块.有谁知道这些条件是什么?

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:

• StackOverflowException
• ExecutionEngineException

当存在 StackOverflowException 时，finally 块将不会被执行，因为堆栈上没有空间可以执行更多代码.当存在 ExecutionEngineException 时也不会调用它，这可能是由于调用 Environment.FailFast() 引起的.

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().
