videoGame.Characters = {"charactername1", "charactername2"}; not working in controller initialization

Question

I keep getting error when initializing the array from the model, any suggestions?

VideoGamesController.cs

using System.Web.Mvc;
using Treehouse.Models;

namespace Treehouse.Controllers
{
    public class VideoGamesController : Controller
    {
        public ActionResult Detail()
        {


         var videoGame = new VideoGame();


             videoGame.Title = "Super Mario 64";
             videoGame.Description = "Super Mario 64 is a 1996 platform video game developed and published by Nintendo for the Nintendo 64.";
             videoGame.Characters = {
             "Mario",
              "Princess Peach",
               "Bowser",
               "Toad",
              "Yoshi" };











            return View(videoGame);
        }
    }
}

Detail.cshtml

@ model VideoGamesController.Models.VideoGames
@{
    ViewBag.PageTitle = "Video Game Detail";
}

<h1>@Model.Title</h1>

<h5>Description:</h5>
<div>@Model.Description</div>

<h5>Characters:</h5>
<div>
    <ul>
        @foreach (var character in Model.Characters)
        {
            <li>@character</li>
        }
    </ul>
</div>

VideoGame.cs

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 string DisplayText
        {
            get
            {
                return Title + " (" + Publisher + ")";
            }
        }
    }
}

Sandra,

Sorry for the slow response! Hopefully you were able to get past this issue. But just in case you haven't...

Before you can initialize an array in C#, you might need to construct it using the new keyword followed by the type of the items that the array will contain. Here's an example of what that looks like:

var characters = new string[]
{
    "Mario",
    "Princess Peach",
    "Bowser",
    "Toad",
    "Yoshi"
};

If you replace the var keyword with the specific array type when declaring my variable, you can use this shorter syntax:

string[] characters =  
{
    "Mario",
    "Princess Peach",
    "Bowser",
    "Toad",
    "Yoshi"
};

If you have a class that defines an array property, like the VideoGame class in the code challenge that you're trying to solve, then you need to do this when initializing the property with a value:

var videoGame = new VideoGame();
videoGame.Characters = new string[] 
{
    "Mario",
    "Princess Peach",
    "Bowser",
    "Toad",
    "Yoshi"
};

Or this works too (notice that the string keyword has been removed):

var videoGame = new VideoGame();
videoGame.Characters = new [] 
{
    "Mario",
    "Princess Peach",
    "Bowser",
    "Toad",
    "Yoshi"
};

I hope this helps.

Thanks ~James
