什么是IL织造？ [英] What is IL Weaving?

问题描述

我今天刚刚看到 Ayende的帖子约PostSharp。我下载了code和尝试过了，我认为这是最酷的，最容易使用的方式来处理AOP，我已经看到了。

I just saw Ayende's post today about PostSharp. I downloaded the code and tried it out, and I thought it was the coolest, most easy to use way to handle AOP that I've seen.

在他的岗位，Ayende说，PostSharp完成它的魔力，通过 IL织造。现在，在一些抽象的层面上，我可以推断出是什么意思，但我想看看是否有一个更详细的答案在那里。不幸的是，第一次在很长一段时间，谷歌来到了空我。所以我想这将是StackOverflow的一个很大的问题（因为我一直在订阅Jeff的博客一对夫妇几年了，知道这个网站是做它的事）。

In his post, Ayende says that PostSharp accomplishes it's magic via IL Weaving. Now, at some abstract level I can deduce what that means, but I wanted to see if there was a more detailed answer out there. Unfortunately, for the first time in a very long time, Google came up empty for me. And so I thought this would be a great question for StackOverflow (since I've been a subscribe to Jeff's blog for a couple years now and knew this site was doing its thing).

那么究竟什么是IL织造，它是怎么做到的呢？

So what exactly is IL Weaving and how is it accomplished?

推荐答案

织是指注射功能集成到现有程序的过程。这在概念上在多个层面进行：

Weaving refers to the process of injecting functionality into an existing program. This can be done conceptually at a number of levels:

• 在源$ C ​​$ C编织将注资源$ C ​​$ C线code编译之前
• 在IL织（用于.NET）增加了code作为IL指令在组装
• 字节code织（用于Java）工程类文件，看到这些评论WRT的 AspectJ的

在理论上，你可以走一条更深入，编织编译为本地指令可执行文件，但是这会增加大量的复杂性，我不知道什么，做到这一点。

In theory you could go one deeper and weave with an executable compiled to native instructions, but this would add a lot of complexity and I'm not aware of anything that does this.
