C＃语言设计的支柱 [英] C# language design pillars

问题描述

在文章（http://www.artima.com/intv/ nonvirtualP.html）安德斯·海尔斯伯格提到的版本是C＃语言设计的支柱之一。有谁知道什么是其他支柱？

解决方案

我是指你一页的C＃规范，它描述的重要因素是走进语言的设计。这说明什么的一些重要因素，并不断有几个报价为：

现代，面向对象和类型安全

-

立即熟悉C，C ++和Java程序员。

-

当代软件设计越来越依赖软件组件在功能自包含和自描述包的形式。这种组件的关键在于，它们的编程模型与属性，方法和事件;它们具有提供了关于组件的声明信息的属性;他们结合自己的文档。 C＃提供的语言构造直接支持这些概念，这使得C＃中创建和使用软件组件是很自然的语言

-

若干C＃特性在坚固耐用的应用援建：垃圾收集[...]异常处理[...]类型-safe设计

-

C＃有一个统一的类型系统。 [...]的任何类型的值可以被储存，运输和操作时以一致的方式

-

要确保C＃程序和库能够以兼容的方式随着时间的推移，大部分重点一直放置在C＃的设计版本。许多编程语言不太重视这个问题，并且，其结果是，这些语言编写的程序依赖的库的更新而不是必要的突破更频繁。即直接通过版本控制因素的影响的C＃的设计在某些方面，其中包括单独的虚拟和override修饰符，方法重载决策规则以及对显式接口成员声明的支持。

In the article (http://www.artima.com/intv/nonvirtualP.html) Anders Hejlsberg mentioned that versioning is one of the pillars of C# language design. Does anybody know what are other pillars?

解决方案

I refer you to page one of the C# specification, which describes the important factors that went into the design of the language. A few quotes that indicate what some of the important factors were, and continue to be:

modern, object-oriented, and type-safe

--

immediately familiar to C, C++, and Java programmers.

--

Contemporary software design increasingly relies on software components in the form of self-contained and self-describing packages of functionality. Key to such components is that they present a programming model with properties, methods, and events; they have attributes that provide declarative information about the component; and they incorporate their own documentation. C# provides language constructs to directly support these concepts, making C# a very natural language in which to create and use software components.

--

Several C# features aid in the construction of robust and durable applications: Garbage collection [...] exception handling [...] type-safe design

--

C# has a unified type system. [...] values of any type can be stored, transported, and operated upon in a consistent manner

--

To ensure that C# programs and libraries can evolve over time in a compatible manner, much emphasis has been placed on versioning in C#’s design. Many programming languages pay little attention to this issue, and, as a result, programs written in those languages break more often than necessary when newer versions of dependent libraries are introduced. Aspects of C#’s design that were directly influenced by versioning considerations include the separate virtual and override modifiers, the rules for method overload resolution, and support for explicit interface member declarations.
