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.

Class diagrams

A class diagram is a structural diagram that is mainly used to provide the design of a piece of object-oriented software. This diagram demonstrates the structure of a software, the attributes and methods of a class, and the relationship between classes in the system. It can be used for development as well as for documentation; software developers frequently use this diagram to get a quick idea of the code and to help fellow developers understand the system. It is also occasionally used by employees involved in the business side of a company.

The following are the three main parts of a class diagram:

  • The class name
  • The attribute section
  • The method section

A class diagram consists of different classes that are represented as boxes or rectangles. A rectangle is normally divided into the aforementioned sections. The first part holds the name of the class, the second...
