What are constructors in C# programs?
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 −
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();
}
}
}Output
Object is being created Length of line : 6
