What is encapsulation in C#?

CsharpProgrammingServer Side Programming

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
