Cannot implicitly convert type `Treehouse.Models.VideoGame' to `Treehouse.Data.VideoGamesRepository'

Could someone please tell me where is wrong here? Much appreciation!

VideoGamesRepository.cs
using Treehouse.Models;

namespace Treehouse.Data
{
    public class VideoGamesRepository
    {
        // TODO Add GetVideoGames method
        public VideoGamesRepository GetVideoGames (int id)
        {
            VideoGamesRepository getVideoGames = null;
            foreach (var i in _videoGames)
            {
                if(i.Id == id)
                {
                    getVideoGames = i;
                    break;
                }
            }
            return getVideoGames;
        }

        // 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.",

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

Did you somehow peek ahead at task 2? But let's concentrate on task 1 for the moment. Here's a few hints:

  • Your code has the method taking an int argument, but...
  • The challenge said "The GetVideoGames method shouldn't accept any parameters."
  • Your code has the method returning a VideoGamesRepository, but...
  • The challenge also said it "...should return the _videoGames private static field." — and...
  • The type of the _videoGames field is VideoGame[].
  • You only need to return the field, you won't need any looping or conditionals.

Ahha~ It seems something with my network. I've been shown the taks2 requirement driectly, without knowing the task1. That makes a lot more sense. Thank you, Steven~!
