什么是抽象类和静态之间的差异？ [英] What's the difference between an abstract class and a static one?

问题描述

无论是实例化。有什么区别，以及在什么情况下可以使用一个或其他？

Neither is instantiable. What are the differences, and in what situations might you use one or the other?

推荐答案

静态表示该类只能有静态成员，你不能建立它的一个实例。这是用于无状态的功能（例如，仅仅定义扩展方法，或实用方法的类型）。您也可以声明静态在非静态类成员。这可以让你附加功能的一类，而不必实例化。

static indicates the class can only have static members and you cannot create an instance of it. This is used for stateless functionality (for example a type that just defines extension methods, or utility methods). You can also declare a member static on a non-static class. This allows you to attach functionality to a type without having to instantiate it.

抽象取值定义的基本结构和功能的所有衍生物类型的共享，但不能使用由自己决定。把它们当作我想，一个蓝色的印刷和合同。这是OOP的一个核心概念。

abstracts define the basic structure and functionality shared by all derivative types, but cannot be used by themselves. Think of them as, I suppose, a blue print and a contract. This is a core concept for OOP.
