Constructor Programming Example C#

Programming Example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace constructor_examples
{
    class ShowMessage
    {
        public ShowMessage()
        {
            Console.WriteLine("Hi, I am default message");
        }

        public ShowMessage(string message)
        {
            Console.WriteLine(message);
        }

        ~ShowMessage()
        {
            Console.WriteLine("I am destructor and I clean the resources and free up memory as soon as program closed");
            Console.ReadLine();
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            ShowMessage sm = new ShowMessage(); //Default constructor
            ShowMessage sm1 = new ShowMessage("I am parameterized constructor. Press Enter to run Destructor"); //parameterized constructor
            Console.ReadLine();
        }
    }
}

Output

Hi, I am default message

I am parameterized constructor. Press Enter to run DestructorI am destructor and I clean the resources and free up memory as soon as program closed
