C＃中的抽象类和接口类之间有什么不同？

What is different between an abstract and an Interface class in C#?

推荐答案

接口不是类，只是合同定义了必须类实现的公共成员。

An interface is not a class, it is just a contract that defines the public members that a class must implement.

抽象类只是无法创建实例的类。通常，您可以使用它来定义一个基类，为派生的类定义一些虚拟方法。

An abstract class is just a class from which you cannot create an instance. Normally you would use it to define a base class that defines some virtual methods for derived classes to implement.
