Shawn,

Can you share the code that you've tried so far to solve this code challenge?

Thanks ~James

using Treehouse.Models;

namespace Treehouse.Data { public class VideoGamesRepository { // TODO Add GetVideoGames method public VideoGame[] GetVideoGames(int id) {
VideoGame[] videoToReturn= null;

        foreach (var videoGame in _videoGames)    
        {
            if (videoGame.Id == id)
            {
                videoToReturn = videoGame;
                break;
            }
        }
        return videoToReturn;

    }
    // 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
        }
    };
}

}

Shawn,

You're actually pretty close to having the correct solution.

1) The GetVideoGames method shouldn't accept any parameters. The goal (or purpose) of that method is to return the complete array of video games (i.e. "give me the all of the video games").

2) The GetVideoGame method is close to what your GetVideoGames method currently is. It should accept in id parameter and return a single video game.

I hope this helps. Let me know how it goes.

Thanks ~James
