Constructors in C#

 C# Constructors

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 the class and it does not have any return type. The following example explains the concept of constructor:

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();

}

}

}
