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().
