I shall be talking in the next article about the Open/Closed Principle(OCP), Liskov Substitution Principle(LSP ), Interface Segregation Principle(ISP ) Dependency Inversion Principle(DIP).ĭo you have any comments or ideas or any better suggestions to share? Using this principle you bring in your domain properties their validation logic together so that the domain model which gets built over this can be used across your application supporting the DRY (Do Not Repeat) principle. Each class now own its own responsibility.īy bringing responsibility together, Objects become a logical container by packaging data with its behavior as new methods/functions.Īny change any one of them would have a lesser impact on the total system. Each class now could be easily be used by other components of the system. Let’s look to make each reason of change as speculated above into single responsibility classes,Ībove as we understood Employee class was broken up into few highly cohesive classes. Let’s combine the behavior together and look for the opportunity for Class update as below, Also, similar SSN extraction or validation logic is needed in other parts of your application, then the code will be duplicated.You will end up instantiating Employee class so that you can use GetLast4Digit() method at other location which is absolutely unnecessary.Employee class now more reason to change due to additional behavior.Extraction or formatting logic of SSN is owned by Employee class.GetLast4Digit methods would produce desired results but there are few problems as listed below, ![]() ? SSN.Substring(index + 1, SSN.Length - index + 1) Var index = SSN.LastIndexOf("-", StringComparison.Ordinal) Lets take a simple example of Employee class, However, you should not to it to all classess where there is no pain.įew examples of motivating class change are like validation, parser, data extraction. If these behavioral characteristics are making a Class to change more than once then there is scope to rethink the class design and there could be a chance to break the class into the subclass if needed. ![]() The behavior to class is defined by their properties, fields, and functions. “ Class should be created using single responsibility principle “Įach Class should have only one reason to change.Īs we understand that classes are just templates until defined with proper behavior. The single responsibility principle talks about the Class and its behavioral characteristic. Let’s get started with the Single Responsibility Principle(SRP) with a few examples using C# code. The SOLID principles of Object-Oriented Design include below five principles, ![]() “ SOLID principles are abstract and language-agnostic in nature”. Each Class should have only one reason to change.
