What are member functions of a class in C#?

CsharpProgrammingServer Side Programming

A member function of a class is a function that has its definition or its prototype within the class definition similar to any other variable. It operates on an object of the class of which it is a member, and has access to all the members of a class for that object.

The following is an example of a member function −

public void setLength( double len ) {
   length = len;
}
public void setBreadth( double bre ) {
   breadth = bre;
}

The following is an example showing how to access member functions in C#.

Example

 Live Demo

using System;

namespace BoxApplication {
   class Box {
      private double length; // Length of a box
      private double breadth; // Breadth of a box
      private double height; // Height of a box

      public void setLength( double len ) {
         length = len;
      }

      public void setBreadth( double bre ) {
         breadth = bre;
      }

      public void setHeight( double hei ) {
         height = hei;
      }

      public double getVolume() {
         return length * breadth * height;
      }
   }

   class Boxtester {
      static void Main(string[] args) {
         Box Box1 = new Box(); // Declare Box1 of type Box
         Box Box2 = new Box();
         double volume;

         // Declare Box2 of type Box
         // box 1 specification
         Box1.setLength(8.0);
         Box1.setBreadth(9.0);
         Box1.setHeight(7.0);

         // box 2 specification
         Box2.setLength(18.0);
         Box2.setBreadth(20.0);
         Box2.setHeight(17.0);

         // volume of box 1
         volume = Box1.getVolume();
         Console.WriteLine("Volume of Box1 : {0}" ,volume);

         // volume of box 2
         volume = Box2.getVolume();
         Console.WriteLine("Volume of Box2 : {0}", volume);

         Console.ReadKey();
      }
   }
}

Output

Volume of Box1 : 504
Volume of Box2 : 6120
