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.

Different constraints of generics

There are different types of constraints available in C# generics:

  • Base class constraints
  • Interface constraints
  • Reference type and value type constraints
  • Multiple constraints

The most common and popular types are base class constraints and interface constraints, so we will focus on them in the following sections.

Base class constraints

The idea of this constraint is that only the classes that extend a base class can be used as generic type. For example, if you have a class named Person and you use this Person class as a base for the Generic constraint, only the Person class or any other class that inherits the Person class can be used as the type argument for that generic class.
