Interfaces are useful in cases where you cannot use class inheritance 在无法使用类继承的情况下接口是很有用的。
Class inheritance demands 类继承要求
The following table shows examples of class inheritance and interface implementation 下表给出了类继承和接口实现的一些示例:
The . net framework security system implements an extensible pattern of derived class inheritance . net framework安全系统实现可扩展模式的派生类继承。
There are several other reasons why you might want to use interfaces instead of class inheritance 以下是为何使用接口继承而不用类继承的一些其他原因:
Value containing the name of the class in which the method was first introduced in the class inheritance hierarchy 值,该值包含方法第一次引入到其继承层次结构的类的名称。
