C# Lesson 16 : More About Classes and Methods

This lesson digs into more details about classes—what exactly happens when you create a new instance of a class? What is a reference to an instance of a class? How does passing the reference to a method affect a class? We also review overloaded methods, static versus instance methods, and constructors.

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

namespace ObjectLifetime
{
    class Program
    {
        static void Main(string[] args)
        {
            Car myCar = new Car();

            // set properties

            Car myOtherCar = myCar;

            Car myThirdCar = new Car("Ford", "Escape", 2005, "White");
          

            myOtherCar = null;
            myCar = null;





        }
    }

    class Car
    {
        public string Make { get; set; }
        public string Model { get; set; }
        public int Year { get; set; }
        public string Color { get; set; }
        public double OriginalPrice { get; set; }

        public Car()
        {
            // You could this from a configuration file, a database, etc.
            // I'll just hardcode in this instance.
            this.Make = "Nissan";
        }

        public Car(string make, string model, int year, string color)
        {
            Make = make;
            Model = model;
            Year = year;
            Color = color;
        }
