10,992 PointsI don't thing i understand what i am being asked to do.
I have added a GetVideoGames method that accepts no parameters and returns _videoGames. I am confused as to how i am suppose to assign _videogames a value i think. should there not be logic to figure out which game is being picked? how can i do this without passing in a value? What am i not getting? here's my code. Thanks!
using Treehouse.Models;
namespace Treehouse.Data
{
public class VideoGamesRepository
{
// TODO Add GetVideoGames method
public VideoGame GetVideoGames()
{
return _videoGames;
}
// 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
{
get
{
return Title + " (" + Publisher + ")";
}
}
}
}

231,275 PointsThe function body is correct. It will return _videogames
but does not assign it any value.
The issue preventing compilation is a type mismatch between the function declaration and the returned item. The _videogames
field is an array ("VideoGame[]
") but the function shown above is declared to return a single item ("VideoGame
").

Take a look at the return type for "_videogames"; it's returning an array "VideoGame[]". Your "GetVideoGames() function needs to have the same return type "VideoGame[]" in order to "return _videogames;".
