C# for Programmers: A Practical Guide

Introduction to Classes

Explore the fundamentals of C# classes by learning how to define classes, create objects, and use members like properties and methods. Understand key concepts such as instance versus static classes, access modifiers, and constructors. This lesson builds a foundation for working with classes in C# programming.

We'll cover the following...

Definition

As in other object-oriented programming languages, the functionality of a C# program is implemented in one or more classes.

The methods and properties of a class contain the code that defines how the class behaves.

Several types of C# classes can be defined, including instance classes (standard classes that can be instantiated), static classes, and structures.

Declaring a Class

Skeleton of declaring class is:

C++
//whatever is written inside [] is optional while declaring a class
//whatever is written inside <> is required while declaring a class
[private/public/protected/internal] class <Desired Class Name> [:[Inherited class][,][[Interface Name 1],[Interface Name 2],...]
{
 //Your code
}

  • Classes are defined using the ...
