在c＃中显示不同类型的列表的正确方法是什么？

Question

Ok, so basically I am creating a project that requires to Create, Read, Update, and Delete. However, I am not referring to a database server, but a List of type. I am trying to figure out how to display the list of Dvd type. My first goal is to be able to display the list of DVDs before starting to implement the update and delete method. Here are my classes:

DvdController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using DvdManager.Models;
using DvdManager.Data;

namespace DvdManager.Controllers
{
    public class DvdController
    {
        List<Dvd> Dvds = new List<Dvd>(10);       


        public void Run()
        {
            Console.WriteLine("Welcome To Dvd Manager");

            CreateDvd();
        }

        private void CreateDvd()//Create
        {
            Dvds.Add(new Dvd(0, "Batman", 2010, "Bruce", 4));
            Dvds.Add(new Dvd(1, "Superman", 2009, "John", 4));
            Dvds.Add(new Dvd(2, "Wonderwoman", 2012, "Omar", 4));
            DisplayDvds();
        }

        private void DisplayDvds() //Read List<Dvd> dvds
        {
            for (int i = 0; i < Dvds.Count; i++)
            {
                Console.WriteLine(Dvds[i]);
            }
        }

        private void SearchDvds() //List
        {

        }

        private void EditDvd(int id, Dvd dvd) //Update
        {

        }

        private void RemoveDvd(int id) //Delete
        {


        }
    }
}

Dvd.cs

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

namespace DvdManager.Models
{
    public class Dvd
    {
        public Dvd(int id, string title, int releaseyear, string director, float rating)
        {
            Id = id;
            Title = title;
            ReleaseYear = releaseyear;
            Director = director;
            Rating = rating;
        }

        int Id { get; }
        string Title { get; set; }
        int ReleaseYear { get; set; }
        string Director { get; set; }
        float Rating { get; set; }


    }
}

The problem is that it displays:

DvdManager.Models.Dvd

But, what I want it to do is display its value by Id, Title, ReleaseYear, Director, Rating. How do I succeed in doing this?

You're printing the default string representation of your class as returned by its ToString . If you want a different output, you can override ToString yourself. Eg:

public override string ToString()
{
   return string.Format
              ("DVD [Id: {0}; Title: {1}; ReleaseYear: {2}; Director: {3}; Rating: {4}]",
               Id, Title, ReleaseYear, Director, Rating);
}
