Two repositories for one view

I have a ViewModel that contains all of my Models, both with it's own repository and I'm trying to put them toguether in the same view... this is in Controller

public ActionResult Index()
        {
            var id = new Receta().Id;

            var viewModel = new Modelos()
            {
                Receta = new Receta(),
                Slide = new Slide(),
                GetRecetas = new Receta[id]

            };

            return View(viewModel);
        }

this is in ViewModel 

public class Modelos
    {
        public Receta Receta { get; set; }
        public Slide Slide { get; set; }
        public Receta[] GetRecetas { get; set; }
    }

and this is one of the repositories 

public class RepositorioRecetas
    {
        private static Receta[] _recetas = new Receta[]
        {
            new Receta()
            {
                Id = 1,
                Titulo = "Receta1",
                DescripcionHtml = "<p>corta descripcion del producto</p>",
                Favorito = false,
                RecetaPasos = "bla bla bla"
            },

            new Receta()
            {
                Id = 2,
                Titulo = "Receta2",
                DescripcionHtml = "<p>corta descripcion del producto</p>",
                Favorito = false,
                RecetaPasos = "bla bla bla"
            },

            new Receta()
            {
                Id = 3,
                Titulo = "Receta3",
                DescripcionHtml = "<p>corta descripcion del producto</p>",
                Favorito = false,
                RecetaPasos = "bla bla bla"
            }
         };

        public Receta[] GetRecetas()
        {
            return _recetas;
        }

        public Receta GetReceta(int id)
        {
            Receta recetaReturn = null;

            foreach (var receta in _recetas)
            {
                if(receta.Id == id)
                {
                    recetaReturn = receta;
                    break;
                }
            }

            return recetaReturn;
        }
    }

yes but here I show more code, I have a nullReferenceException but I do set the id so I don't get why I'm not being able to loop through the foreach 

@if(Model.Recetas != null)
{
<div class="row">
    @foreach (Receta receta in Model.Recetas)
    {
        <div class="col-md-4">
            <div class="well">
                <h4>@Html.ActionLink(receta.Titulo, "Receta", new { id = receta.Id, @class = "Recetas" })</h4>
                <a href="@Url.Action("Receta", new { id = receta.Id })">
                    <img src="~/img/fotos/@receta.CoverImageFileName" alt="@receta.MostrarTexto" class="img-responsive" />
                </a>
            </div>
        </div>
    }
</div>
}

I don't quite understand what you're intending from the code, but when you create the viewmodel in the controller, perhaps the array is being filled with nulls instead of being empty (length 0)? Try setting a breakpoint at the controller's return and examine the viewmodel at that point.
