// this function working perfectly
public dynamic CountTable()
{
    return (from t in db.Users
            group t by t.Type into g
            select new
            {
                type = g.Key,
                count = g.Count(),
                ActiveGroups = (from t in g group t by t.Active into ag select new { active = ag.Key, count = ag.Count() })
            }).ToList();
}

    // and this loop working in MVC Controller
    foreach (dynamic uct in ur.CountTable())
    {
        int x = uct.count;
    }

But not working in template:

Line 12: @foreach (dynamic uct in ViewBag.ur.CountTable())
Line 13: {
Line 14:     int adet = uct.count;
Line 15: }

Line 14: ‘object’ does not contain a definition for ‘count’

Why? What can I do?

Answer 1

Anonymous types are compiled into internal classes.

The standard binder used by dynamic will only bind to public members of public classes.
Therefore, you cannot use it with anonymous types from a different assembly.
