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.

Tuples

A tuple is a data structure that holds a set of data. Tuples are mainly helpful when you want to group data and use it. Normally, a C# method can only return one value. By using a tuple, it is possible to return multiple values from a method. The Tuple class is available under the System.Tuple namespace. A tuple can be created using the Tuple<> constructor or by an abstract method named Create that comes with the Tuple class.

You can fix any data type in a tuple and access it using Item1, Item2, and so on. Let's look at an example to get a better idea of this:

var person = new Tuple<string, int, string>("Martin Dew", 42, "Software Developer"); // name, age, occupation
or
var person = new Tuple.Create("Martin Dew", 42, "Software Developer");

Let's take a look at how to return a tuple from a method by using the...
