abstact类和接口（带有示例）之间有什么区别。 [英] What is the difference between an abstact class and an interface (with examples).

问题描述

我想要明确解释这种差异以及它可以在项目中使用的位置。

I want a clear explanation about that difference and where it can be used in projects.

推荐答案

区别很简单：

接口不是类，不能实例化。它不能包含任何具体代码，只能包含抽象定义。您可以继承一个接口以及一个基类，只要您完成合同并实现它所需的方法和属性。



抽象类是不同的：你仍然无法实例化它 - 这意味着你不能说

The difference is simple:
An interface is not a class, and cannot be instantiated. It cannot contain any concrete code, only abstract definitions. You can inherit an Interface as well as a single base class, provided you complete the "contract" and implement the methods and properties it requires.

An abstract class is different: you still can't instantiate it - which means you can't say

MyAbstractBase mab = new MyAbstractBase();

但如果从派生类派生，则无法同时从任何其他类派生。抽象类可以包含具体代码，如果它没有在派生类中重写，将使用它。



这是一个相当复杂的主题，你应该真的从C＃教程开始了解详细信息： http://csharp.net-tutorials.com/classes/interfaces/ [ ^ ]是一个很好的基础。

but if you derive from an abstract class you cannot derive from any other class at the same time. An abstract class can contain concrete code, which will be used if it isn't overridden in the derived class.

This is a fairly complicated subject, and you should really start with a C# tutorial for the details: http://csharp.net-tutorials.com/classes/interfaces/[^] is a good basis.
