Challenge Task 2 of 2 Add a GetVideoGame method to the VideoGamesRepository class.

Kind of stuck with my bugs. Could anyone please give me a hint? Much appreciation here.

VideoGamesRepository.cs
using Treehouse.Models;

namespace Treehouse.Data
{
    public class VideoGamesRepository
    {
        // TODO Add GetVideoGames method
        VideoGame[] GetVideoGames(int id)
        {
            VideoGame[] returnGame = null;
            foreach(var VG in _videoGames)
            {   
                if (VG.Id == id)
                {   
                    returnGame = VG;
                    break;
                }     
            }
            return returnGame;
        }
        // TODO Add GetVideoGame method

        private static VideoGame[] _videoGames = new VideoGame[]
        {
            new VideoGame()
            {
                Id = 1,
                Title = "Super Mario 64",
                Description = "Super Mario 64 is a 1996 platform video game developed and published by Nintendo for the Nintendo 64.",
                Characters = new string[]
                {
                    "Mario",
                    "Princess Peach",
                    "Bowser",
                    "Toad",
                    "Yoshi"
                },
                Publisher = "Nintendo",
                Favorite = true
            },
            new VideoGame()
            {
                Id = 2,
                Title = "Mario Kart 64",
                Description = "Mario Kart 64 is a 1996 go-kart racing game developed and published by Nintendo for the Nintendo 64 video game console.",
                Characters = new string[]
                {
                    "Mario",
                    "Princess Peach",
                    "Bowser",
                    "Toad",
                    "Yoshi"
                },
                Publisher = "Nintendo",
                Favorite = false
            }
        };

    }
}
VideoGame.cs
namespace Treehouse.Models
{
    // Don't make any changes to this class!
    public class VideoGame
    {
        public int Id { get; set; }
        public string Title { get; set; }
        public string Description { get; set; }
        public string[] Characters { get; set; }
        public string Publisher { get; set; }
        public bool Favorite { get; set; }

        public string DisplayText
        {
            get
            {
                return Title + " (" + Publisher + ")";
            }
        }
    }
}

:point_right: It looks like you might be confusing task 1 and task 2.

Someone posted nearly the same thing just two days ago. Did you somehow peek ahead at task 2? But let's concentrate on task 1 for the moment. Here's a few hints:

  • Your loop tries to assign a single VideoGame (VG) to an array of them (returnGame).
  • Your code has the method taking an int parameter, but...
  • The challenge said "The GetVideoGames method shouldn't accept any parameters."
  • The challenge also said it "...should return the _videoGames private static field." — so...
  • You only need to return the field, you won't need any looping or conditionals.

Hi, Steven, thank you so much for your answer. It seems I mixed up task1 and task2 with my carelessness, since the two names are so similar. Then I replaced task1 with task2 :P. Thank you for the hint. Now I've passed my exercise.
