Dependency injection is a design pattern used in object-oriented programming to separate the creation and usage of dependencies. It allows us to write more modular and testable code by removing the dependency on concrete implementations and instead relying on abstractions. In C#, there are several ways to implement dependency injection. Here, I will explain three …

C# XML documentation is a way to document code using XML tags within the code file. This documentation can be extracted into an external file that can be used for different purposes like generating documentation, providing intellisense suggestions, and creating API documentation.

If an exception occurs, it is caught by the catch block and appropriate actions can be taken to handle the exception. Here is an example of how to implement exception handling in C#: “`csharp try …

Encapsulation is one of the principles of object-oriented programming and it is a way to hide the internal details or implementation details of an object and exposing only what is necessary. In C#, encapsulation is achieved using access modifiers such as public, private, protected, and internal. These access modifiers control the accessibility of members (variables, …

Inheritance is a key concept in object-oriented programming where one class inherits the properties and behaviors of another class. In C#, a derived class can inherit from a single base class using the “colon” syntax. For example, let’s say we have a base class called “Animal” that defines common properties and behaviors of all animals: …

Object-oriented programming (OOP) is a programming paradigm that is focused on using objects to represent and manipulate data. It organizes code into objects, which can have properties and methods. Here are some key concepts in object-oriented programming: 1. Classes: Classes are blueprints or templates for creating objects. They define the properties (attributes) and behaviors (methods) …
