Project

Object-oriented programming (OOP) has been around for decades. As the original object-oriented language, C# is a mainstay in the world of computer programming.

All the concepts of object-oriented programming that C# developers love to have in their arsenal are explained in detail along with relevant coding examples and exercises in this course.

This course is unique in its nature as it follows a project-based learning approach. Throughout the course, a real-world example of vending machine is followed to help the learners develop a firm understanding of the stated OOP concepts.

The learners will not only be able to play around with the project,  they’ll also be able to see all the concepts in action in this project.

# The `this` Reference Variable

The `this` reference variable exists for every class. It refers to the current instance of a class. The `this.memberName` specifies that we are accessing the `memberName` of the current object.

## Accessing a Field
We can use the `this` when we have a method argument which has the same name as a **field**.  It's always a good convention for the beginners to use the `this` keyword in their class implementation when initializing or accessing the fields. This will help us avoid any confusion or errors.

Let's see it in action:

In this lesson, you will learn about the 'this' reference variable.
