i'm working on class latitude , longitude of address 3 different providers (just comparison sake).
note, might lot at, info there reference if want. data below <hr> not necessary at.
my google maps datacontract works champ. bing , mapquest datacontracts aren't playing nice. think issue has deal nested collections of json bing , mapquest, , don't know how deal them.
here function processes data.
''# because json response google, mapquest, , bing drastically ''# different, need consume response little differently ''# each api. ''# ################################## ''# bing broken ''# ################################## ''# here we're handling bing provider if provider = apiprovider.bing dim res = directcast(serializer.readobject(request.getresponse().getresponsestream()), bingresponse) dim resources bingresponse.resourceset.resource = res.resourcesets(0).resources(0) dim point = resources.point coordinates .latitude = point.coordinates(0) .longitude = point.coordinates(1) end ''# ################################## ''# google works champ ''# ################################## ''# here we're handling google provider elseif provider = apiprovider.google dim res = directcast(serializer.readobject(request.getresponse().getresponsestream()), googleresponse) dim resources googleresponse.result = res.results(0) dim point = resources.geometry.location coordinates .latitude = point.lat .longitude = point.lng end ''# ################################## ''# mapquest broken ''# ################################## ''# here we're handling mapquest provider elseif provider = apiprovider.mapquest dim res = directcast(serializer.readobject(request.getresponse().getresponsestream()), mapquestresponse) dim resources mapquestresponse.result = res.results(0) dim point = resources.locations.latlng coordinates .latitude = point.lat .longitude = point.lng end end if and here 3 datacontracts

system.nullreferenceexception: object reference not set instance of object. on line
.latitude = point.lat when testing bing error

dim resources bingresponse.resourceset.resource = res.resourcesets(0).resources(0) fyi, i'll post json response each looks like.

for map quest:
shouldn't public property locations m_locations public property locations() m_locations()? assume array notation in vb. seem you're taking latlng array object , not instance of location in array.
found similar question data contract (accepted answer) same response. looking differences not spotting them yet...
