4,055 PointsI get the error "Does your 'GetVideoGames' method not allow any parameters?" Code seems to be written as in video.
I can't find a solution to this error. How can I move on?
using Treehouse.Models;
namespace Treehouse.Data
{
public class VideoGamesRepository
{
// TODO Add GetVideoGames method
public VideoGame GetVideoGames(int id)
{
VideoGame videoGameToReturn = null;
foreach (var videoGame in _videoGames)
{
if (videoGame.Id == id)
{
videoGameToReturn = videoGame;
break;
}
}
return videoGameToReturn;
}
// 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
}
};
}
}
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

- The GetVideoGames method shouldn't accept any parameters.
- The GetVideoGames method should return the
_videoGames
private static field.
The code here is doing something completely different. In fact, it looks a lot like the "GetVideoGame" (singular) methad that will be created for task 2. But you still need to observe this hint also given in the instructions: "Important: In each task of this code challenge, the code you write should be added to the code from the previous task". So the task 1 code for "GetVideoGames" (plural) should remain as-is when you create the task 2 code.

15,587 Pointsthere is one method that you have to create for each task, in the first task GetVideoGames with "s" in the second task make a other method under the first one you created in the previous task "GetVideoGame" without "s"
