Dependency Inversion Principle C# Example

The Dependency Inversion Principle (DIP) is one of the SOLID principles of object-oriented design, and it states that high-level modules should not depend on low-level modules. Instead, both should depend on abstractions. Furthermore, abstractions should not depend on details; details should depend on abstractions. In other words, it suggests that: <blockquote> High-level modules should not depend on low-level modules. Both should depend on abstractions. Abstractions should not depend on details. Details should depend on abstractions. </blockquote> <img alt="" src="https://miro.medium.com/v2/resize:fit:512/1*w69gXB1KueCKRIy4xswX6g.png" style="height:512px; width:512px" /> Dependency Inversion Principle C# Example The goal of the Dependency Inversion Principle is to create a more flexible, maintainable, and scalable software architecture by reducing tight coupling between components. This principle encourages the use of interfaces, abstract classes, and dependency injection to achieve the desired decoupling. In C#, the Dependency Inversion Principle can be demonstrated through the use of interfaces or abstract classes to define abstractions, and then injecting these abstractions into classes rather than directly instantiating concrete implementations. Here’s an example to illustrate this principle: Let’s say we have a simple scenario where we have a high-level class <code>ReportGenerator</code> that depends on a low-level class <code>Database</code> to fetch data and generate a report.
