What are destructors in C# programs?
A destructor is a special member function of a class that is executed whenever an object of its class goes out of scope.
It has exactly the same name as that of the class with a prefixed tilde (~), for example, our class name is Demo.
public Demo() { // constructor
Console.WriteLine("Object is being created");
}
~Demo() { //destructor
Console.WriteLine("Object is being deleted");
}Let us see an example to learn how to work with Destructor in C#.
Example
using System;
namespace LineApplication {
class Line {
private double length; // Length of a line
public Line() { // constructor
Console.WriteLine("Object is being created");
}
~Line() { //destructor
Console.WriteLine("Object is being deleted");
}
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());
}
}
}Output
Object is being created Length of line : 6 Object is being deleted
