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.

Working with DataReaders and DataAdapters

DataReaders and DataAdapters are core objects of a data provider. These are some of the most important features that ADO.NET provides. Let's see how to work these objects.

DataReaders

Every provider has DataReaders. Underneath, all classes do the same thing. SqlDataReader, OdbcDataReader, and OleDbDataReader all implement the IDataReader interface. The main use of DataReader is to read data from a data source when it is coming from a stream. Let's take a look at the different properties that a data reader has:

Property

Description

Depth

The depth of nesting for a row

FieldCount

Returns the number of columns in a row

IsClosed

Returns TRUE if DataReader...
