Question

I’ve got the JSON coming back like this:

{   'responseData': [{     'responseData': {       'translatedText': 'elefante'     },     'responseDetails': null,     'responseStatus': 200   }, {     'responseData': {       'translatedText': 'Burro'     },     'responseDetails': null,     'responseStatus': 200   }],   'responseDetails': null,   'responseStatus': 200 } 

And I need to parse it into a ResponseData object I have set-up:

public class ResponseData  {     public string translatedText = string.Empty;     public object responseDetails = null;     public HttpStatusCode responseStatus = HttpStatusCode.OK;     public List <ResponseData> responseData { get;set; } } 

I Deserialize it like this:

JavaScriptSerializer serializer = new JavaScriptSerializer(); ResponseData translation =  serializer.Deserialize<ResponseData>(responseJson); 

But no matter what the translated text is always empty.

you should think about the JSON object graph represented in that string.

You can nest types for deserializating objects with different properties/fields using generics like so:

class Response < T > {  public ResponseData < T > [] responseData = new ResponseData < T > [0];  public HttpStatusCode responseStatus;  public object responseDetails; }  public class ResponseData < TInternal > {  public TInternal responseData;  public HttpStatusCode responseStatus;  public object responseDetails; }  public class TranslatedText {  public string translatedText; }  [Test] public void Sample() {  var input = @ ' {   ''   responseData '': [{     ''     responseData '': {      ''      translatedText '': ''      elefante ''     },     ''     responseDetails '': null,     ''     responseStatus '': 200    }, {     ''     responseData '': {      ''      translatedText '': ''      Burro ''     },     ''     responseDetails '': null,     ''     responseStatus '': 200    }],    ''   responseDetails '': null, ''   responseStatus '': 200  }  ';   var json = new JavaScriptSerializer();  var response = json.Deserialize < Response < TranslatedText >> (input);  Assert.AreEqual(response.responseData[0].responseData.translatedText, 'elefante');  Assert.AreEqual(response.responseStatus, HttpStatusCode.OK); }
