C# Object-Oriented Programming (OOP)

Syntax

class ClassName
{
    //member variables and methods
}

Example

class Employee
{
    public string Name;
    public int EmpID;
    public void GetEmpDetails()
    {
        //code to get employee details
    }
}

Output

A blueprint for creating objects of the class.

Explanation

C# is an object-oriented programming language. Object-oriented programming (OOP) is a programming paradigm that uses objects to represent and manipulate data. In C#, a class is a blueprint for creating objects. It defines a set of member variables and methods that can be used to create and manipulate objects of the class type.

In the example above, a class named "Employee" is defined with member variables "Name" and "EmpID" and a method "GetEmpDetails". The "public" access modifier is used to indicate that these members can be accessed from outside the class.

Once a class is defined, objects of the class can be created and used to perform various operations. Objects are created using the "new" keyword, and class members are accessed using the "." operator.

Use

Object-oriented programming concepts are used extensively in C# programming. Classes, objects, inheritance, encapsulation, and polymorphism are some of the key concepts in OOP that are used to develop robust, scalable, and maintainable applications.

Important Points

• A class is a blueprint for creating objects.
• Class members can be variables or methods.
• Members can have different access modifiers like public, private, or protected.
• Objects are created from a class using the "new" keyword.
• Class members are accessed using the "." operator.
• OOP concepts like inheritance, encapsulation, and polymorphism are used in C# programming.

Summary

C# supports object-oriented programming concepts and provides the ability to define classes, create objects, and use them to perform various operations. Classes define the structure and behaviors of objects, while objects are instances of classes that can be created and manipulated in code. Familiarity with object-oriented programming is essential for developing robust and efficient C# applications.
