📚 Lập trình C#

Classes and Objects You learned from the previous chapter that C# is an object-oriented programming language. Everything in C# is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake. A Class is like an object constructor, or a "blueprint" for creating objects. When a variable is declared directly in a class, it is often referred to as a field (or attribute). It is not required, but it is a good practice to start with an uppercase first letter when naming classes. Also, it is common that the name of the C# file and the class matches, as it makes our code organized. However it is not required (like in Java).
