android - How to deserialize my data that I sent to my webservice?

Question

How do I deserialize this string that I sent as a json object in asp.net webservice.

HttpClient client = new DefaultHttpClient();  

HttpPost post = new HttpPost("http://server/NCO/webservice.asmx/GetNRIC");   

post.setHeader("Content-type", "application/json");

post.setHeader("Accept", "application/json");

JSONObject obj = new JSONObject();

obj.put("ic", "s1111111b");

post.setEntity(new StringEntity(obj.toString(), "UTF-8"));

HttpResponse response = client.execute(post);

您将需要一个实用程序类，其中包含如下方法。

 public static T JsonDeserialize<T> (string jsonString)
 {
     DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
     MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
     T obj = (T)ser.ReadObject(ms);
     return obj;
 }

RequestDTO requestDTO = JsonHelper.JsonDeserialize<RequestDTO>(jsonString);
