BindingFlags.Public | BindingFlags.NonPublic;
        const MemberTypes PROP_FIELD = MemberTypes.Property | 
MemberTypes.Field;
        Type type = typeof(Kontekst);
        foreach (MemberInfo member in type.GetMembers(FLAGS))
        {
            if ((member.MemberType & PROP_FIELD) == 0) continue;
            ColumnAttribute col = Attribute.GetCustomAttribute(member, 
typeof(ColumnAttribute)) as ColumnAttribute;
            if (col == null) continue;
            Console.WriteLine("canbenull=={0}", col.CanBeNull);
        }
