What is encapsulation in C#?

Encapsulation in C# prevents access to implementation details. Implement Encapsulation in C# using access specifiers.

The following are the access specifiers supported by C# −

• Public
• Private
• Protected
• Internal
• Protected internal

Encapsulation can be understood by taking an example of private access specifier that allows a class to hide its member variables and member functions from other functions and objects.

In the following example we have length and width as variables assigned private access specifier −

Example

 Live Demo

using System; namespace RectangleApplication {    class Rectangle {       private double length;       private double width;       public void Acceptdetails() {          length = 10;          width = 15;       }       public double GetArea() {          return length * width;       }       public void Display() {          Console.WriteLine("Length: {0}", length);          Console.WriteLine("Width: {0}", width);          Console.WriteLine("Area: {0}", GetArea());       }    }    class ExecuteRectangle {       static void Main(string[] args) {          Rectangle r = new Rectangle();          r.Acceptdetails();          r.Display();          Console.ReadLine();       }    } }

Output

Length: 10 Width: 15 Area: 150
