reading HttpwebResponse json response, C#

Question

In one of my apps, I am getting the response from a webrequest. The service is Restful service and will return a result similar to the JSON format below:

{     "id" : "1lad07",     "text" : "test",     "url" : "http:\/\/twitpic.com\/1lacuz",     "width" : 220,     "height" : 84,     "size" : 8722,     "type" : "png",     "timestamp" : "Wed, 05 May 2010 16:11:48 +0000",     "user" : {         "id" : 12345,         "screen_name" : "twitpicuser"     } }    

and here is my current code:

    byte[] bytes = Encoding.GetEncoding(contentEncoding).GetBytes(contents.ToString());     request.ContentLength = bytes.Length;      using (var requestStream = request.GetRequestStream()) {          requestStream.Write(bytes, 0, bytes.Length);          using (var twitpicResponse = (HttpWebResponse)request.GetResponse()) {              using (var reader = new StreamReader(twitpicResponse.GetResponseStream())) {                  //What should I do here?              }          }      } 

How can I read the response? I want the url and the username.

Answer 1

First you need an object

public class MyObject {   public string Id {get;set;}   public string Text {get;set;}   ... } 

Then in here

    using (var twitpicResponse = (HttpWebResponse)request.GetResponse()) {          using (var reader = new StreamReader(twitpicResponse.GetResponseStream())) {             JavaScriptSerializer js = new JavaScriptSerializer();             var objText = reader.ReadToEnd();             MyObject myojb = (MyObject)js.Deserialize(objText,typeof(MyObject));         }      } 

I haven't tested with the hierarchical object you have, but this should give you access to the properties you want.

JavaScriptSerializer System.Web.Script.Serialization

I'd use RestSharp - https://github.com/restsharp/RestSharp

Create class to deserialize to:

public class MyObject {     public string Id { get; set; }     public string Text { get; set; }     ... } 

And the code to get that object:

RestClient client = new RestClient("http://whatever.com"); RestRequest request = new RestRequest("path/to/object"); request.AddParameter("id", "123");  // The above code will make a request URL of  // "http://whatever.com/path/to/object?id=123" // You can pick and choose what you need  var response = client.Execute<MyObject>(request);  MyObject obj = response.Data;
