C#: Destructors

Destructors are used to destruct instances of classes. Destructors are mainly used to clean the resources.

Syntax

~ClassName(){

}

A class can only have one destructor. Destructors cannot be called explicitly, they are invoked automatically. A destructor does not take modifiers or have parameters.

Program.cs

using System;

public class Employee
{
    private int id;
    private String firstName;
    private String lastName;

    public Employee(int id, String firstName, String lastName)
    {
        Console.WriteLine("Initializing the object");
        this.id = id;
        this.firstName = firstName;
        this.lastName = lastName;
    }

    public int getId()
    {
        return id;
    }

    public void setId(int id)
    {
        this.id = id;
    }

    public String getFirstName()
    {
        return firstName;
    }

    public void setFirstName(String firstName)
    {
        this.firstName = firstName;
    }

    public String getLastName()
    {
        return lastName;
    }

    public void setLastName(String lastName)
    {
        this.lastName = lastName;
    }

    ~Employee()
    {
        Console.WriteLine("Destructiing the object");
    }
}


class Program
{

    static void Main(string[] args)
    {
        Employee emp1 = new Employee(1, "Hari krishna", "Gurram");
    }

}

Output
