Question

The following code throws error at statement :

Result res = (Result)stdserialize.ReadObject(ms);

And the error is : There was an error deserializing the object of type TrackLocation.MainPage+Result. End element ‘types’ from namespace ” expected. Found element ‘item’ from namespace ”.

HttpClient gClientRequest = new HttpClient();
System.Uri gURI = new Uri("http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true");
HttpResponseMessage gResponse = await gClientRequest.GetAsync(gURI);
string   strStream = await gResponse.Content.ReadAsStringAsync();
MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(strStream));
DataContractJsonSerializer stdserialize = new DataContractJsonSerializer(typeof(Result));
Result res = (Result)stdserialize.ReadObject(ms);

any idea how to fix this issue.Any help would be greatly appreciated.

Answer 1

I just converted the JSON to XMl and found the types to be repeated(check screen shot below) but in your datacontract its
[DataMember(Name = “types”)]
public string Types;

Just put this as

        [DataMember(Name = "types")]
        public string[] Types;

and it should work
