在codeproject里有一个答案是很不错的,具体实现就不剧透了,如感兴趣,可以戳:http://www.codeproject.com/Articles/703634/SOLID-architecture-principles-using-simple-Csharp?msg=4729987#xx4729987xx O:OCP, Open Closed Principle 开放封闭原则 上一个“场景”过了SRP阶段我们要继续开始OCP阶段了, OCP简单来说就...
SOLID由罗伯特·C·马丁在 21 世纪早期引入,指代了面向对象编程和面向对象设计的五个基本原则,SOLID其实是以下五个单词的缩写: Single Responsibility Principle:单一职责原则 Open Closed Principle:开闭原则 Liskov Substitution Principle:里氏替换原则 Interface Segregation Principle:接口隔离原则 Dependency Inversion Princi...
设计模式中的SOLID原则,分别是单一原则、开闭原则、里氏替换原则、接口隔离原则、依赖倒置原则,遵循前辈们总结出来的五大原则可以使程序解决紧耦合,更加健壮。来看个表单: 简拼 全拼 汉字 简单介绍 SRP The Single Responsibility Principle 单一责任原则 对象应该仅具有单一的功能 OCP The Open Closed Principle ... ...
In this article you will learn about Open Closed Principle, how to implement it step by step and why it is important while developing a project.
The OCP principle encourages extending behavior throughinheritanceor interfaces rather than modifying existing code. However, excessive use ofpolymorphismcan slow down execution. Similarly, theDIPprinciple often leads to dependency injection frameworks, which can increase startup times and reduce efficiency. ...
So to sum up, the Dependency Inversion Principle is the last part of the SOLID principles which introduce an abstraction between high and low-level components inside our project to remove dependencies between them. If someone asks: „Should I put an effort to implement the DIP into my code?
Open-Closed principle (OCP) The Open-Closed Principle emphasizes that a class should be open for extension but closed for modification. This means that you should be able to add new functionality to a class without altering its existing code. ...
Consider a scenario where the user would like thesumof additional shapes like triangles, pentagons, hexagons, etc. You would have to constantly edit this file and add moreif/elseblocks. That would violate the open-closed principle. A way you can make thissummethod be...
