In previous console application post we learned about create console application, namespaces in c# and constructor in c# console application.
In this c# .net tutorials we will learn what is destructor and how to use destructor in c#.net.
Destructor in C#
Destructor are used to destruct instances of classes.
In .net framework there is a facility to cleanup unused or un-referenced object automatically called garbage collection.
Some time we need to cleanup unused object manually, for destruct manually unused object we use destructor method.
A class have only one destructor.
Destructor will call after execution of program.
Syntax of destructor :
~ myclass()
{
}
Class DesExample
{
~ DesExample() // destructor
{}
}
Example of destructor in c#.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace DesctExample
{
class MyExample
{
public MyExample()//Default constructor
{
Console.WriteLine("Example of Default Constructor");
}
~MyExample() // Destructor
{
Console.WriteLine("Example of Destructor");
}
}
class Program
{
static public void Test()
{
MyExample obj = new MyExample();
}
static void Main(string[] args)
{
Test();
GC.Collect();
Console.ReadLine();
}
}
}
The output of destructor example is :
Example of Default Constructor
