![]() ![]() For this simple example, we have considered only two attributes of the Author entity, i.e. In this example, the Author class follows the YAGNI principle of implementing minimal functionality. class ProgramĬonsole.WriteLine($"Sum of a and b is: ") Note how the AddIntegers method has been reused. The following code snippet illustrates how you can implement the DRY principle using methods. In this way, the code will be shared throughout all types, such that if you ever need to modify the code, you only have to update the interface. Using interfaces: Code shared across classes without a common base class may be moved into an interface and implemented by the relevant classes.This approach ensures that modifications to the code can be made in a single location rather than in each separate class that extends the base class. Using classes and inheritance: When lines of code are spread across many classes and methods, they can be relocated to a parent class, which all of the derived classes can then inherit.Any required changes can be done at a single location in your code base. It is often easier to move the code that is repeated in multiple places into a method and call it from everywhere. Using methods: Methods implement the DRY principle by allowing you to centralize code that will be used in multiple parts of your application.You can implement the DRY principle in C# in the following ways: The DRY principle may be used to enhance collaboration among developers and to teach new developers how to contribute to an existing code base more successfully, in addition to enhancing the quality and maintainability of the code. It can help developers reduce the amount of code they need to write and maintain and eliminate code redundancies, leading to fewer defects and a more effective use of resources. Modularity can help in making changes and additions to the application more efficient and seamless, with less risk of errors creeping into the system.ĭRY can be applied to all aspects of your software development process including code, configuration files, documentation, and the user interface. The DRY principle encourages developers to write code that is clean, modular, and reusable. Adhering to this principle would ensure that altering the code in one location would automatically update every occurrence of that code throughout the application. DRY emphasizes easing the maintainability of your application’s source code across all stages of the application’s lifecycle. In software development, the “Don’t repeat yourself” principle means you should avoid the duplication of code in your application. NET 7 console application project to work with code examples of the DRY, YAGNI, and KISS principles in the subsequent sections of this article. In the “Additional information” window, choose “.NET 7.0 (Standard Term Support)” as the framework version you would like to use.In the “Configure your new project” window shown next, specify the name and location for the new project.In the “Create new project” window, select “Console App (.NET Core)” from the list of templates displayed.Assuming Visual Studio 2022 is installed in your system, follow the steps outlined below to create a new. ![]() NET Core console application project in Visual Studio.
