C# Class and Object Concept

One of the most fundamental concepts in our C# programming studies is the concept of class and object. In this article, we will examine the C# class and object concept in detail. Classes define a specific data structure, while objects represent instances of these classes. Thus, we create a more modular and manageable code structure.

What is a Class?

A class is a template that defines an object’s attributes (properties) and behaviors (methods). In C#, the class keyword is used to create a class. Below you can find a simple example of a class:

public class Araba
{
    public string Marka;
    public string Model;
    public int Yil;

    public void BilgiYaz()
    {
        Console.WriteLine($"Marka: {Marka}, Model: {Model}, Yıl: {Yil}");
    }
}

What is an Object?

Objects are defined as instances created from classes in terms of data/memory. When a class is defined, we can create one or more objects using it. Below is a code example that shows how to create an object from the Araba class defined above:

class Program
{
    static void Main(string[] args)
    {
        Araba araba1 = new Araba();
        araba1.Marka = "Toyota";
        araba1.Model = "Corolla";
        araba1.Yil = 2020;

        araba1.BilgiYaz();
    }
}

Conclusion

The concepts of class and object in C# are the cornerstones of object-oriented programming. Classes help better organize code during the design process, while with objects we can represent the real-world counterparts of these classes. Thanks to this structure, we can manage complex applications more easily. Gaining more knowledge about classes and objects in C# programming will advance your software development skills.
