.NET DataContractJsonSerializer, Nested collections throwing me for a loop - asp.net

Question

I'm working on a class to get the Latitude and Longitude of an address by 3 different providers (just for comparison sake).
Note, this might look like a lot to look at, but some info is just there for reference if you want. Data below the <hr> is not necessary to look at.
My Google Maps DataContract works like a champ. But my Bing and MapQuest DataContracts aren't playing so nice. I think the issue has to deal with the Nested collections of the JSON for Bing and MapQuest, and I just don't know how to deal with them.
Here is the Function that processes the Data.
''# Because the JSON Response from Google, MapQuest, and Bing are drastically
''# different, we need to consume the response a little differently
''# for each API.
''# ##################################
''# BING IS BROKEN
''# ##################################
''# Here we're handling the Bing Provider
If Provider = apiProvider.Bing Then
Dim res = DirectCast(serializer.ReadObject(request.GetResponse().GetResponseStream()), BingResponse)
Dim resources As BingResponse.ResourceSet.Resource = res.resourceSets(0).resources(0)
Dim point = resources.point
With coordinates
.latitude = point.coordinates(0)
.longitude = point.coordinates(1)
End With
''# ##################################
''# GOOGLE WORKS LIKE A CHAMP
''# ##################################
''# Here we're handling the Google Provider
ElseIf Provider = apiProvider.Google Then
Dim res = DirectCast(serializer.ReadObject(request.GetResponse().GetResponseStream()), GoogleResponse)
Dim resources As GoogleResponse.Result = res.results(0)
Dim point = resources.geometry.location
With coordinates
.latitude = point.lat
.longitude = point.lng
End With
''# ##################################
''# MAPQUEST IS BROKEN
''# ##################################
''# Here we're handling the MapQuest Provider
ElseIf Provider = apiProvider.MapQuest Then
Dim res = DirectCast(serializer.ReadObject(request.GetResponse().GetResponseStream()), MapQuestResponse)
Dim resources As MapQuestResponse.Result = res.results(0)
Dim point = resources.locations.latLng
With coordinates
.latitude = point.lat
.longitude = point.lng
End With
End If
And here are the three DataContracts

Public Property lng As String
End Class
End Class
End Class
End Class
When testing MapQuest I get this error
System.NullReferenceException: Object reference not set to an instance of an object.
on line
.latitude = point.lat
When testing Bing I get this error
System.IndexOutOfRangeException: Index was outside the bounds of the array.
on line
Dim resources As BingResponse.ResourceSet.Resource = res.resourceSets(0).resources(0)
FYI, I'll also post what the JSON Response for each looks like.

Answer 1

For map quest:
Shouldn't Public Property locations As m_Locations be Public Property locations() As m_Locations()? I assume this is array notation in VB. It would seem you're taking the latLng from the Array object and not the instance of the location in the array.
Found a similar question with a data contract (accepted answer) for the same response. Looking for differences but not spotting them yet...
