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 handling best practices

As you can see, there are different ways in which you can handle exceptions: sometimes you can throw exceptions, sometimes you can use the finally block, and sometimes you can use multiple catch blocks. Consequently, there is a chance that you can get confused at the beginning if you don't have enough experience with exception handling. But thanks to the C# community, there are some best practices for exception handling. Let's have a look at some of them:

  • Use a finally block to close/clean up dependent resources that could cause a problem in the future.
  • Catch the specific exception and handle it properly. Use multiple catch blocks if needed.
  • Create your own exceptions if needed and use them.
  • Handle exceptions as soon as possible.
  • Don't use a general exception handler if you can handle an exception using a specific handler.
  • The...
