Hands-On Object-Oriented Programming with C#

By: Raihan Taher

Overview of this book

Object-oriented programming (OOP) is a programming paradigm organized around objects rather than actions, and data rather than logic. With the latest release of C#, you can look forward to new additions that improve object-oriented programming. This book will get you up to speed with OOP in C# in an engaging and interactive way. The book starts off by introducing you to C# language essentials and explaining OOP concepts through simple programs. You will then go on to learn how to use classes, interfacesm and properties to write pure OOP code in your applications. You will broaden your understanding of OOP further as you delve into some of the advanced features of the language, such as using events, delegates, and generics. Next, you will learn the secrets of writing good code by following design patterns and design principles. You'll also understand problem statements with their solutions and learn how to work with databases with the help of ADO.NET. Further on, you'll discover a chapter dedicated to the Git version control system. As you approach the conclusion, you'll be able to work through OOP-specific interview questions and understand how to tackle them. By the end of this book, you will have a good understanding of OOP with C# and be able to take your skills to the next level.

Implementation of OOP in C#

In the previous chapter, we looked at classes, objects, and the four principles of OOP. In this chapter, we will learn about some C# language features that make the language an OOP language. Without knowing these concepts, writing object-oriented code with C# programming could be difficult, or will prevent you from using it to its full potential. In Chapter 2, Hello OOP - Classes and Objects, we learned that abstraction, inheritance, encapsulation, and polymorphism are the four basic principles of OOP, but we haven't yet learned how the C# language can be used to fulfill these principles. We are going to discuss this topic in this chapter.

In this chapter, we will cover the following topics:

  • Interfaces
  • The abstract class
  • The partial class
  • The sealed class
  • Tuples
  • Properties
  • Access specifiers for classes
