推荐答案

希望这会有所帮助

抽象类与接口 [

Hope this helps

Abstract Class versus Interface[^]

您做了什么研究?

接口是合同，它不包含任何代码.抽象类可以具有代码.在.NET中，您不能从多个类派生，但是可以实现多个接口.

抽象类与接口 [

And what research have you done?

An interface is a contract, it contains no code. An Abstract class can have code. In .NET you can''t derive from multiple classes however you can implement multiple interfaces.

我已经回答了类似的问题.除了其他答案外，请参见有关如何决定使用接口还是抽象类的讨论:

I already answered similar question. In addition to other Answers, please see the discussion on how to decide on use of interfaces vs. abstract classes: How to decide to choose Abstract class or an Interface[^].

Also, one fundamental difference is that interfaces allows for multiple inheritance, in contrast to classes (abstract or not). This is called week form of multiple inheritance and has serious design implications.
