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.

Exception class

An exception is simply a class in C#. This has a few properties and methods. The four most commonly used properties are as follows:

Property Description
Message This contains what the exception is about.
StackTrace This contains the method call-stack information.
TargetSite This gives an object that contains the method where the exception happened.
InnerException This gives the instance of the exception that caused the exception.
Exception class properties and methods

One of the most popular methods in this class is ToString(). This method returns a string that contains information about the exception. The exception is easier to read and understand when it is represented in string format.

Let's look at an example of using these properties and methods:

using System;

namespace ExceptionCode
{
class Program
{
static void Main(string[] args)
{
try
