本规范描述了用C#编程语言编写的程序的形式，并对其进行了解释。它描述:
-C#程序的表示
-C#语言的语法和约束
-解释C#程序的语义规则
-C#的一致性实现所施加的限制和限制
本规范没有描述
-将C#程序转换为数据处理系统使用的机制
-数据处理系统调用C#应用程序的机制
-转换输入数据以供C#应用程序使用的机制；
-输出数据由C#应用程序生成后进行转换的机制
-超过任何特定数据处理系统或特定处理器容量的程序及其数据的大小或复杂性
-能够支持一致性实施的数据处理系统的所有最低要求。

This specification describes the form and establishes the interpretation of programs written in the C# programming language. It describes:
— The representation of C# programs;
— The syntax and constraints of the C# language;
— The semantic rules for interpreting C# programs;
— The restrictions and limits imposed by a conforming implementation of C#.
This specification does not describe
— The mechanism by which C# programs are transformed for use by a data-processing system;
— The mechanism by which C# applications are invoked for use by a data-processing system;
— The mechanism by which input data are transformed for use by a C# application;
— The mechanism by which output data are transformed after being produced by a C# application;
— The size or complexity of a program and its data that will exceed the capacity of any specific data-processing system or the capacity of a particular processor;
— All minimal requirements of a data-processing system that is capable of supporting a conforming implementation.
