CIL，CLS，而CTS在.NET [英] CIL, CLS, and CTS in .NET

问题描述

什么是 CIL ，的 CTS 和 CLS 在.NET和它们之间有什么区别呢？

What is the CIL, CTS, and CLS in .NET and what is the difference between them?

推荐答案

CIL（通用中间语言）是字节code，您的C＃或Visual Basic code编译为。这是.NET执行引擎的机器code。

CIL (Common Intermediate Language) is the byte code to which your C# or Visual Basic code is compiled. It's the "machine code" of the .NET execution engine.

的CTS（通用类型系统）是类型（类和结构）在编译级的重新presentation。基本上，它是说所有.NET语言将使用重presenting种（类和结构）的常用方法。

The CTS (Common Type System) is the representation of types (classes and structures) at the compiled level. Basically, it's saying that all .NET languages will use a common way of representing types (classes and structures).

在CLS（通用语言规范）是API的一组约束和一组对语言要求的互补性。如果库是符合CLS（即附着所有约束），那么任何符合CLS语言将能够使用该API。相反，一个符合CLS语言被保证是能够使用任何符合CLS库。例如，一个符合CLS的语言保证支持的Int32，所以CLS保证它的安全库作家使用的Int32在它们的API。

The CLS (Common Language Specification) is a set of constraints on APIs and a complementary set of requirements on languages. If a library is CLS-compliant (i.e. adheres to all the constraints), then any CLS-compliant language will be able to use that API. Conversely, a CLS-compliant language is guaranteed to be able to use any CLS-compliant library. For example, a CLS-compliant language is guaranteed to support Int32, so the CLS guarantees it's safe for library writers to use Int32 in their APIs.
