A class constructor is a special member function of a class that is executed whenever we create new objects of that class.
A constructor has exactly the same name as that of class and it does not have any return type.
Constructor has the same name as the class name −
class Demo { public Demo() {} }
The following is an example −
using System; namespace LineApplication { class Line { private double length; // Length of a line public Line() { Console.WriteLine("Object is being created"); } public void setLength( double len ) { length = len; } public double getLength() { return length; } static void Main(string[] args) { Line line = new Line(); // set line length line.setLength(6.0); Console.WriteLine("Length of line : {0}", line.getLength()); Console.ReadKey(); } } }
Object is being created Length of line : 6
