C# Intermediate: Classes, Interfaces and Object-oriented Programming

An in-depth, step-by-step guide to classes, interfaces and object-oriented programming, with many real-world examples.

Whether you want to use C# to build web apps, mobile apps, desktop apps or games, understanding C# classes, interfaces and principles of object-oriented programming is crucial.

This course is the second part of my best-selling C# series where you'll learn:

  • How to work with classes, constructors, fields, properties, methods and indexers
  • How to use encapsulation to reduce the impact of changes
  • How to improve the robustness of your code
  • How to re-use code using inheritance and composition
  • Why composition is better than inheritance
  • How to build extensible applications using polymorphism
  • How to develop loosely-coupled, extensible and testable applications using interfaces


Each section is equipped with a balanced mix of theory and practice. At the end of each section you'll get exercises to master the concepts you learn in that section.


WHAT OTHER STUDENTS WHO HAVE TAKEN THIS COURSE SAY:

"I’ve actually landed my first job as a Junior software developer. I owe a lot of it to you because your courses have been EXTREMELY helpful. May God bless you and your efforts to create high quality courses. This has really changed my life from working as a security guard and doing websites for free, now I am a professional." -Danish Jafri


"Your courses have given me the confidence to get out of my dead end job and apply for a full time coding job. I am very happy to say that I just finished the job interview and they gave me the job!!!" -Dan Farnell


"Outstanding quality! I have come to learn that all Mosh's courses are top notch. This course is no different! The content is beautifully designed, well organized with great examples, and delivered in a clear and concise manner (with great video and audio quality)! I also loved that this course includes exercises. Fantastic stuff!" -Roger Sæle


"Love it! This guy definitely knows what he's talking about. He strives to make his courses as comprehensive as possible and he teaches you several tricks along the way." -Jeb Watson


"As with all of his courses his passion and love for programming is infectious. He does a great job of intermixing theory with hard examples and cautions with practicality. If you learn better by watching and examples then reading and theory this is a must watch to move beyond the learning the syntax of c#." -Michael Paul


"Excellent course! All of Mosh's courses are very much worth taking if you really want to learn C# in a professional way. Not only does Mosh clearly describe the syntax of the language and explain the language concepts, but he also constantly emphasizes the importance of good programming practices" -Tony Zampini
