Object Oriented Programming with .NET

Get Up to Speed with Object Oriented Techniques using Visual Studio

Object-oriented programming (OOP) is a programming paradigm using "objects" to design applications and computer programs. Programming techniques may include features such as data abstraction, encapsulation, messaging, modularity, polymorphism, and inheritance. Almost all modern programming languages support OOP and in this course we focus on VB and C#.

Purpose of this course

The content is focused on object and class creation, properties, methods, overloading, polymorphism, inheritance abstract classes, shared/static properties and methods, interfaces, events, delegates, and lists. The course highlights the differences between the previous versions of Visual Studio.

Who is this course for

.NET programmers who have basic language skills in VB or C# who which to develop their skills in object oriented programming, using the latest Microsoft development technologies. Those delegates working towards MCPD certification.

You will learn how to
  • Define Object Oriented Programming (OOP)
  • Compare Structured and OO Programming
  • Understand the differences between Value and Reference types and the Heap and the Stack
  • Understand Data Aggregation and Data Hiding
  • Understand Encapsulation
  • Understand Constructors and Overloading
  • Override Methods (also known as Polymorphism, or Virtual Methods)
  • Understand the difference between overriding in Java and .NET
  • Understand the difference between Instance and Shared/static methods and properties
  • Declare and Raise your own Events and write your own Event Handlers
  • Understand the strengths/weaknesses of traditional arrays vs Lists, ArrayLists, Hashtables and Dictionaries
  • Understand the differences between an Interface and an Abstract Class
  • See where Interfaces fit in with Service Oriented Architecture (SOA)
Benefits for your organisation

OOP is not just popular, it’s ubiquitous. Allowing your developers to grasp the OOP concepts will result in them producing code that is more reliable, scalable and, most importantly, maintainable. It will also result in happier developers!

Benefits for you as an individual

Whether you program in VB.NET, C#, Java, Ruby, Python, C++ or even JavaScript, you’ll need to know the fundamentals of Object Oriented Programming. This course shows all the critical OOP features, allowing you to understand the structure of most of the code you’ll bump into for the next few years. OOP is notoriously difficult to teach yourself, but this course makes it all seem easy. After this 3-day course, you will effortlessly incorporate classic OOP principals into all your future code.
