问题描述

用的是什么，从.NET产生IL文件（使用MSIL assembler- ilasm.exe）？

What is the use of IL file generated from .NET (using MSIL assembler- ilasm.exe)?

我从 http://msdn.microsoft.com/en-阅读美国/库/ 496e4ekx.aspx 但我不知道使用IL文件从.NET产生的（使用MSIL assembler- ilasm.exe）。 任何一个可以解释我？

推荐答案

您可能要直接使用IL在那些（诚然罕见的）情况下，当如C＃高级语言不提供precision或者功能需要。

You might want to use IL directly in those (admittedly rare) situations when a higher level language like C# doesn't provide the precision or features you need.

例如，有在 System.Dynamic 一些功能，从动态语言如IronPython的不能很容易地在C＃中使用使用。直接去IL可以帮助那些你需要混合的语言，也许是一个第三方库的情况。

For instance, there are some features in System.Dynamic that are used from the dynamic languages such as IronPython that can't easily be used in C#. Going straight to IL can help in those situations where you need to mix languages, perhaps for a third-party library.

在另一方面，的拆卸的对IL可以是非常有用的，你可以找到code是什么，编译器为你的C＃程序产生。这是无价的微优化的性能问题，例如。

On the other hand, disassembling to IL can be very useful as you can find exactly what the code is that the compiler generated for your C# program. This is invaluable for micro-optimising performance issues, for example.
