Question

With ASP .NET MVC3.

In my controller I have this portion of code

    MasterMindDnetEntities context = new MasterMindDnetEntities();
    List<MasterMindDnet.Games> Games = (from g in context.Games
                                        join u in context.Users on g.g_u_Id equals u.u_Id
                                        where u.u_Login == User.Identity.Name
                                        select g).ToList();
    @ViewBag.Games = Games;
    @ViewBag.GameCount = Games.Count;
    return View("Index");

In the controll, Games works fine as a list.

In my view I have:

@for (int i = 0; i < ViewBag.GameCount; i++)
{
    ViewBag.Games = ViewBag.Games[i];

At line ViewBag.Games = ViewBag.Games[i];, I get the exception :

Cannot apply indexing with [] to an expression of type
‘System.Data.Entity.DynamicProxies.

In a previous version I had i < ViewBag.Games.Count; instead of i < ViewBag.GameCount; and it said that ViewBag.Games does not have a definition for Count.

How could I solve this ?

Thank you for your help.

Answer 1

Problem of dynamic proxies mean that you have to declare “statically” what’s in your ViewBag.

So in your View, just make :

@{
    List<MasterMindDnetGames> games = ViewBag.Games;

    for (var i = 0; i < games.Count; i++) {
       var game = games[i];//declare it in the scope you need
       //bla bla bla
    }
}
