反序列化jSON Google AJAX Translation API

Question

我有这样的JSON回来了：

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

我需要将它解析为我已设置的ResponseData对象：

    public class ResponseData
    {
        public string translatedText = string.Empty;

        public object responseDetails = null;

        public HttpStatusCode responseStatus = HttpStatusCode.OK;
        public List<ResponseData> responseData { get; set; }
    }

我将它反序列化为：

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

但无论翻译的文本总是空的。

您应该考虑该字符串中表示的JSON对象图。

您可以使用泛型来嵌套用于反序列化具有不同属性/字段的对象的类型：

 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);

}
