Classes
Classes is a core part of C#. In this case file you'll learn what it is, why it matters, and how to use it in real code.
Understanding classes well means you can read other people's C# code with confidence, and avoid the most common beginner mistakes in this area.
Key points:
- What classes means in the context of C#
- A minimal example you can run or read in the playground on the right
- A common mistake to avoid when working with classes
// C#: Classes
using System;
class Demo {
static void Main() {
Console.WriteLine("Exploring Classes");
}
}
Tip: Try changing a value in the code on the right and re-running it — small experiments are the fastest way to build real intuition for classes.
