    public class DimensionesViewModel
    {
        // Variables Properties
        IList<Dimension> _listaDimensiones = new List<Dimension>();

        // Properties
        public IList<Dimension> ListaDimensiones { get{return _listaDimensiones;} private set{} }

        //开发者_Go百科 Constructor
        public DimensionesViewModel()
        {
            _listaDimensiones = Dimensiones.GetListaFiltros(null);
        }

    }

    [HandleError]
    public class DimensionesController : Controller
    {

Error: Object reference not set to an instance of an object.

You need to pass an instance of the ViewModel class to your view from the controller action method:

    public ActionResult Index()
    {
        var model = new DimensionesViewModel();
        return View(model);
    }

You're not passing in the model to your view.

    public ActionResult Index()
    {
        return View();
    }

Should be something like:

    public ActionResult Index()
    {
        var model = new DimensionesViewModel();
        return View(model);
    }

You're not setting the Views Model property to anything.

In your controller passing your list to the View method.

return View(new DimensionesViewModel());

You need to give to your view an instance of the class DimensionesViewModel. For that, you need to do something like this in the Index action:

public ActionResult Index()
{
  return View(new DimensionesViewModel());
}
