Introduction

Public access specifier means, any public member can be accessed from inside and outside the class. Public access specifier allows a class to expose its member variables and functions to other functions and objects.

Example

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace public_access_specifier

{

class rectangle

{

public double length; /*Public member variable define Length and width , which can be access in

main() function, using in instance of the rectangle class , named rect. */

public double width;

public double ReturnArea() /*The member function ReturnArea() and Display() can also access

variables directly without using any instance of the class*/

{

return length * width;

}

public void Display()

{

Console.WriteLine("Length={0}", length);

Console.WriteLine("Width={0}", width);

Console.WriteLine("Area={0}", ReturnArea());

}

class ExecuteArea

{

static void Main(string[] args)

{

rectangle rect = new rectangle();

rect.length = 4.5;

rect.width = 3.5;

rect.Display(); /*The member function Display() is also declare Public, so can also be accessed

from main() using in instance of the Rectangle class, named rect */

}

Output
