Question

I’m trying to parse some JSON using the System.Runtime.Serialization.Json library. The documentation seems a little sparse and I’m confused as to how to accomplish what I need. Here is the format for the JSON I need to parse through.

{
 "data": {
  "translations": [
   {
    "translatedText": "ne",
    "detectedSourceLanguage": "en"
   }
  ]
 }
}

Here is a set of classes that represent the JSON data structure you have. I have chosen names that will help you correlate the type with the location in the JSON string.

[DataContract]
class RootObject
{
  [DataMember(Name = "data")]
  public DataObject Data { get; set; }
}

[DataContract]
class DataObject
{      
  [DataMember(Name="translations")]
  public List<Translation> Translations { get; set; }
}

[DataContract]
class Translation
{
  [DataMember(Name = "translatedText")]
  public string TranslatedText { get; set; }
  [DataMember(Name = "detectedSourceLanguage")]
  public string DetectedSourceLanguage { get; set; }
}

Now the following is an example of deserializing your JSON string into this structure.

  string json = @"
    {
      ""data"": {
      ""translations"": [
                          {
                            ""translatedText"": ""ne"",
                            ""detectedSourceLanguage"": ""en""
                          }
                        ]
                }
    }";

  var jsonSerializer = new DataContractJsonSerializer(typeof(RootObject));
  var o = (RootObject)jsonSerializer.ReadObject(
    new MemoryStream(Encoding.Unicode.GetBytes(json)));
