ASCIIEncoding与Encoding之间的区别 [英] Difference Between ASCIIEncoding and Encoding

问题描述

我知道Encoding可以用于初始化对象来执行任何类型的编码，ASCII，Unicode，UTF-8等。
在我看来，所有这些都足以执行任何类型的编码，然后需要使用ASCIIEncoding？

解决方案

Encoding 除了作为所有编码器的基类之外，还为命名的子类提供静态属性访问器。

Encoding.ASCII 返回一个 ASCIIEncoding 的实例，反过来，子类 Encoding 并传递代码页 0x4e9f （ US-ASCII ）到基础构造函数。

I understand that Encoding can be used to initialize object to perform any type of Encoding, ASCII, Unicode, UTF-8 etc. It appears to me that all these are sufficient for performing any kind of encoding, then what is the need for ASCIIEncoding?

解决方案

The Encoding class, in addition to being the base class of all encoders, provides static property accessors to the named subclasses.

Encoding.ASCII returns an instance of ASCIIEncoding which, in turn, subclasses Encoding and passes the codepage 0x4e9f (US-ASCII) to the base constructor.
