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.

Exploring ADO.NET with Examples

If you have any exposure to web development, you might have heard of ASP.NET, which is a framework for web development. Similarly, if you have worked with databases before in .NET projects, you should have heard of or used ADO.NET. ADO.NET is a framework that's similar to ASP.NET, but instead of web development, this framework is used for database-related work. ActiveX Data Object (ADO) was an old technology created by Microsoft, but the evolution to ADO.NET has been extraordinary. ADO.NET contains classes and methods that can be used to easily establish a connection with a database management system such as SQL Server or Oracle. Not only that, it also provides methods and objects that help to execute commands in the database, such as select, insert, update, and delete.

We need a separate framework for database connection and activity because...
