Deserializing JSON in WP7

Question

I have this JSON which I am trying to read on Windows Phone. I\'ve been playing with DataContractJsonSerializer and Json.NET but had not much luck, especially r

Answer 1

The solution below uses Json.NET. It deserializes the JSON string first to XML, then uses LINQ to XML to iterate all people nodes and convert them to instances of the Person class.

private class Person
{
    public string ID { get; set; }
    public string Name { get; set; }
    public string Age { get; set; }
}

// deserializes your JSON and creates a list of Person objects from it
private void button1_Click(object sender, RoutedEventArgs e)
{
    // your JSON
    string json =
        "{\"lastUpdated\":\"16:12\",\"filterOut\":[],\"people\": " +
        "[{\"ID\":\"x\",\"Name\":\"x\",\"Age\":\"x\"},{\"ID\":\"x\",\"Name\":\"x\",\"Age\":\"x\"},{\"ID\":\"x\",\"Name\":\"x\",\"Age\":\"x\"}]," +
        "\"serviceDisruptions\":" +
        "{" +
        "\"infoMessages\":" +
        "[\"blah blah text\"]," +
        "\"importantMessages\":" +
        "[]," +
        "\"criticalMessages\":" +
        "[]" +
        "}" +
        "}";

    // deserialize from JSON to XML
    XDocument doc = JsonConvert.DeserializeXNode(json, "root");

    // iterate all people nodes and create Person objects
    IEnumerable people = from person in doc.Element("root").Elements("people")
                                 select new Person()
                                 {
                                     ID = person.Element("ID").Value,
                                     Name = person.Element("Name").Value,
                                     Age = person.Element("Age").Value
                                 };

    // this is just demonstrating that it worked
    foreach (Person person in people)
        Debug.WriteLine(person.Name);
}

Don't forget the imports:

using Newtonsoft.Json;
using System.Xml.Linq;
using System.Diagnostics;

And this is how the deserialized JSON looks like as XML document (for the curious people out there):

  16:12
  
    x
    x
    x
  
  
    x
    x
    x
  
  
    x
    x
    x
  
  
    blah blah text
