在.NET中，将空的方法调用进行优化呢？ [英] In .NET, will empty method calls be optimized out?

问题描述

由于空的方法体，将JIT优化了电话（我知道C＃编译器不会）。我将如何去寻找呢？我应该使用什么工具，在哪里我可以找？

Given an empty method body, will the JIT optimize out the call (I know the C# compiler won't). How would I go about finding out? What tools should I be using and where should I be looking?

因为我相信它会被要求，为空方法的原因是preprocessor指令。

Since I'm sure it'll be asked, the reason for the empty method is a preprocessor directive.

推荐答案

这章有相当好的治疗JIT的优化，做好在页面上搜索的方法是空的，它的一半左右一路下跌的文章 -

This chap has quite a good treatment of JIT optimisations, do a search on the page for 'method is empty', it's about half way down the article -

显然，空的方法都得到了优化，通过内联的是实际上没有code。

Apparently empty methods do get optimised out through inlining what is effectively no code.

@克里斯：我的确意识到了二进制的，这些方法还是将一部分，而这些是JIT的优化:-)。在一个半相关的说明，在Scott Hanselman曾在发布版本调用堆栈上内联一个相当有趣的文章：

@Chris: I do realise the that the methods will still be part of the binary and that these are JIT optimisations :-). On a semi-related note, Scott Hanselman had quite an interesting article on inlining in Release build call stacks:
