namespace WebApplication1.Controllers
{
public class HomeController : Controller

    OdeToFood _db = new OdeToFood();

    public ActionResult Index()
    {
        var model = _db.Restaurants.ToList();

        return View(model);
    }

    public ActionResult About()
    {
        //ViewBag.MessageA = "Your application description page.";

        var model = new AboutModel();
        model.Name = "Jimmit Mukesh Raval";
        model.Location = "Mulund";

        ViewBag.Message = "Jimmit Mukesh Raval";

        return View(model);
    }

    public ActionResult Contact()
    {
        ViewBag.Message = "Your contact page.";

        return View();
    }
}
}

Restaurant.cs

namespace WebApplication1.Models
{
public class Restaurant
{
    public int Id { get; set; }
    public string Name{ get; set; }
    public string City { get; set; }
    public string Country { get; set; }
    public ICollection<RestaurantReview> Reviews{ get; set; }
}
}

RestaurantReview.cs

namespace WebApplication1.Models
{
public class RestaurantReview
{
    public int Id { get; set; }
    public int Rating { get; set; }
    public string Body { get; set; }
    public string RestaurantId { get; set; }
}
}

OdeToFood.cs

namespace WebApplication1.Models
{
public class OdeToFood:DbContext
{
    public DbSet<Restaurant> Restaurants { get; set; }
    public DbSet<RestaurantReview> Reviews { get; set; }
}
}

任何人都可以帮助我，我哪里不对？

尝试添加：

 public class OdeToFood : DbContext
    {
        public OdeToFood()
         : base("OdeToFood")
        {
        }
        public DbSet<Restaurant> Restaurants { get; set; }
        public DbSet<RestaurantReview> Reviews { get; set; }
    }

为什么我的实体框架网站无法正常工作？
