API десериализации значков Foursquare

Для недавних проверок это довольно просто:

Dim UserSelfCheckins As FourSquare.UserSelfCheckins.Root
Dim ser As New JavaScriptSerializer()
UserSelfCheckins = ser.Deserialize(Of FourSquare.UserSelfCheckins.Root)(jsonstring)

С такими вспомогательными классами:

Namespace UserSelfCheckins
    Public Class Root
        Public Property meta As MetaProperties
        Public Property response As ResponseProperties
    End Class

    Public Class MetaProperties
        Public Property code As String
    End Class

    Public Class ResponseProperties
        Public Property checkins As UserSelfCheckins
    End Class

    Public Class UserSelfCheckins
        Public Property count As Integer
        Public Property items As List(Of UserSelfCheckinProperties)
    End Class

    Public Class UserSelfCheckinProperties
        Public Property createdAt As Long
        Public Property venue As VenueProperties
    End Class

    Public Class VenueProperties
        Public Property id As String
        Public Property name As String
        Public Property location As LocationProperty
        Public Property categories As List(Of CategoriesProperty)
    End Class

    Public Class LocationProperty
        Public Property city As String
        Public Property state As String
    End Class
End Namespace

Вы можете отобразить их с помощью этого:

 @For Each item In UserSelfCheckins.response.checkins.items
        @<li>
        @item.venue.name
        @item.venue.location.city
        @item.venue.location.state
        </li>
 Next

Чего я не могу понять, так это того, как это сделать для списка значков, поскольку структура не постоянна. Это Response>Badges>[badgeID]>BadgeName. Поскольку BadgeID отличается для каждого из них, у меня возникают проблемы с написанием соответствующих классов.

После этого мне нужно найти разумный способ показать значки, которые фактически разблокированы.

Вот фрагмент JSON из двух значков — один разблокирован.

Думаю, я понял это. Чего мне не хватало, так это превращения уровня значков в словарь строк и объектов.

Мне нужна была эта модель:

 Namespace UserBadges
    Public Class Root
        Public Property meta As MetaProperties
        Public Property response As ResponseProperties
    End Class

    Public Class MetaProperties
        Public Property code As String
    End Class

    Public Class ResponseProperties
        Public Property badges As Dictionary(Of String, badge)
    End Class

    Public Class badge
        Public Property name As String
        Public Property Description As String
        Public Property Image As BadgeImage
        Public Property unlocks As List(Of Checkins)
    End Class

    Public Class Checkins
        Public Property checkins As List(Of CheckinInfo)
    End Class

    Public Class CheckinInfo
        Public Property createdAt As String
    End Class

    Public Class BadgeImage
        Public Property prefix As String
        Public Property name As String
    End Class

End Namespace

И это:

 UserBadges = ser.Deserialize(FourSquare.UserBadges.Root)(FSQjson)
 For Each item In UserBadges.response.badges
      @item.Value.Image.prefix
      @item.Value.Image.name
      @item.Value.name
      @item.Value.Description     
 Next
