How to parse this JSON in android (returned from .NET webservice)

Question

I have ASP.NET webservice which return Person object in JSON format. Please see following Webservice code:

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public Person person() {

    Person me = new Person();
    me.name = "Mark";
    me.lastname = "Brawn";

    return me;
}


public class Person {

 public String name;
 public String lastname;
}

Then I tried to parse this response in Android client and I get following JSON Output:

{
"d": {
    "__type": "WebService+Person",
    "name": "Mark",
    "lastname": "Brawn"
}

}

This output seems valid JSON format, but I would like to know how to properly get properties from this output ( name, lastname...).

In android I parsed this output:

JSONObject json = new JSONObject(result);
json.getString("name");

But I get an exception:

07-12 19:07:14.708: W/System.err(21575): org.json.JSONException: No value for name

So actually i would like to get value "name", and "lastname" from this JSON. Any help appriciated.

The JSON Object being created by "result" is likely the parent JSON object, while "name" is in the nested JSON object. Try json.getObject("d").getString("name").

Actually it works :). But I'm confused. Why is ASP.NET webservice returning this kind of JSON? Why not only "name" and "surname" properties? – rootpanthera Aug 19 '13 at 21:10
Not sure, that's a question for the developer who created the ASP.NET web service. Please accept the answer in addition to your upvote. – Alex Wang Aug 19 '13 at 21:11
Strange. Because I saw a lot of sample code regarding parsing JSON in android, but I never saw an output like mine ( and solution like yours ). But ok , at least it works. Thank you! – rootpanthera Aug 19 '13 at 21:13
FYI, the "d" is apparently a security feature in ASP.Net: http://stackoverflow.com/questions/6588589/why-do-asp-net-json-web-services-return-the-result-in-d – Emma Burrows Aug 26 '13 at 20:50
