In such cases, the interfaces that are implemented appear after the base class, separated by commas.
在这种情况下，被实现的接口放在基类之后，以逗号分隔。
The main advantage in using interfaces is that classes can implement more than one of them, as opposed to being able to derive from a single base class (abstract or otherwise).
使用接口的主要优点是可以实现的类不止一个，而这些类不能从一个单一的基类派生(抽象或相反)。

When a base type list contains a base class and interfaces, the base class must come first in the list.
当基类型列表包含基类和接口时，基类必须是列表中的第一项。
For reference types, an implicit conversion always exists from a class to any one of its direct or indirect base classes or interfaces.
对于引用类型，隐式转换始终存在于从一个类转换为该类的任何一个直接或间接的基类或接口的情况。
