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#.
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(); } } }
Volume of Box1 : 504 Volume of Box2 : 6120
