In this course, you’ll learn the fundamentals of Object-Oriented Programming (OOP) in C# and .NET. By the end of the course, you’ll have a solid understanding of core OOP principles such as abstraction, encapsulation, inheritance, and polymorphism, all essential for building robust applications. This course is designed for beginners and will guide you step by step, helping you grasp C# classes, fields, methods, interfaces, inheritance, and more. The course starts with an introduction to the basics of OOP and helps you get comfortable with C# by building a simple project. You will learn how classes and objects play a role in structuring applications and dive deeper into fields, methods, and constructors that form the foundation of C# programming. Throughout the course, you will work through practical coding assignments that reinforce your understanding. In the subsequent sections, the course explores advanced concepts like interfaces, inheritance, and polymorphism. You’ll understand how to create and implement interfaces, how inheritance allows for code reuse, and how polymorphism enhances the flexibility of your code. With each section, you’ll build on the concepts learned earlier, gaining more confidence in your programming skills. This course is perfect for anyone starting with C# or OOP. It’s tailored for beginners and requires no prior experience in programming. By the end, you will have the ability to develop object-oriented applications using C# and .NET, laying a solid foundation for further learning in software development.

Syllabus

Introduction to the Course

In this module, we will introduce the course structure, objectives, and the approach to building a practical project. We will guide you through the tools and concepts you will be learning, preparing you for hands-on programming. Lastly, a recap will summarize the key takeaways from this section and preview what's coming next.

Understanding C# Class

In this module, we will delve into the fundamentals of OOP in C# and understand the concept of classes and objects. We will break down the essential pillars of OOP, including abstraction, and demonstrate their role in creating modular code. A recap will consolidate your learning before you move on to the next section.

Understanding C# Class Fields

In this module, we will explore how fields in C# are utilized within classes, distinguishing between constants, static fields, and read-only fields. You will also gain an understanding of the important distinction between value and reference types, enriching your knowledge of memory management. A recap will prepare you for the next learning stage.

Understanding C# Class Methods

In this module, we will dive into methods in C#, exploring how constructors, destructors, and overloading enhance class functionality. You will also learn about encapsulation, one of the core principles of OOP, ensuring the secure handling of data. The section will conclude with a review of key concepts and a preview of the upcoming topics.

Understanding C# Interfaces

In this module, we will examine the concept of interfaces in C#, their implementation, and their role in enhancing the modularity and reusability of code. You will learn about static members and properties within interfaces, along with the reasons why interfaces are crucial in object-oriented programming. A summary will recap the key lessons before moving to the next section.

Understanding C# Inheritance

In this module, we will cover inheritance, one of the pillars of OOP, and its practical implementation in C#. We will also explore key concepts such as constructor behavior in base and derived classes, access modifiers, and why multiple inheritance is not supported in C#. The section will conclude with a recap and a look ahead at the next module.

Understanding C# Polymorphism

In this module, we will explore polymorphism, the final pillar of OOP, focusing on method hiding, method overriding, and abstract classes in C#. You will also understand the importance of preventing polymorphism in certain scenarios. The section will end with a brief summary and an introduction to the next topics.
