Add a GetVideoGame method to the VideoGamesRepository class

What's wrong here?

VideoGamesRepository.cs
using Treehouse.Models;

namespace Treehouse.Data
{
    public class VideoGamesRepository
    {
        // TODO Add GetVideoGames method
        public VideoGame[] GetVideoGames()
        {   
            return _videoGames;
        }
        // TODO Add GetVideoGame method
        public VideoGame GetVideoGame(int id)
        {
            VideoGame videoGameToReturn = null;

            foreach (var videoGame in _videoGames)
            {                
                if (videoGame.Id == id)
                {
                    videoGameToReturn = videoGame;

                    break;
                }
            }
        }


        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",

                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",

                Publisher = "Nintendo",
                Favorite = false
            }
        };
    }
}
VideoGame.cs
namespace Treehouse.Models
{
    // Don't make any changes to this class!
    public class VideoGame

        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 + ")";
            }
        }
    }

You forgot one thing....

You did great selecting the videGameToReturn, but after the loop you forgot to actually return it. :smirk:
