C# JSON & Parsing

I have managed to set-up a simple webClient that calls my WCF service in a WP8 application. The method fires perfectly fine and the data is returned via the OpenReadCompleted event.

What I wish to do now is convert the returned data which is in JSON and populate a collection of objects.

This is the webClient code:

private void Button_Click(object sender, RoutedEventArgs e)
{
    var webClient = new WebClient();
    var uri = new Uri("urlGoesHere");
    webClient.OpenReadCompleted += webClient_OpenReadCompleted;
    webClient.OpenReadAsync(uri);
}

This is the OpenReadComplete code:

void webClient_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
    var sr = new StreamReader(e.Result);
    var data = sr.ReadToEnd();
    //ToDo - Create a collection of SightingTypes and populate
    sr.Close();
    sr.Dispose();
}

And this is the POCO/Object which I want populating:

public class SightingType
{
    public string Name { get; set; }
    public string BrandId { get; set; }
}

UPDATE

When I hover over data, I can see the following (shortened):

{\"Message\":null,\"Status\":0,\"CurrentVersionNumber\":26,\"SightingTypes\":[{\"BrandId\":\"brands\\/1\",\"DestinationUserIds\":[\"users\\/33\"],\"Id\":\"SightingTypes\\/8\",\"IsDeleted\":false,\"IsEnabled\":true,\"Name\":\"Michael Johnson\"}

What I am particularly interested in is the Name and the BrandId.

I would recommend checking out JSON.Net. It comes with a JSON Serializer that should meet your need:

SightingType deserializedSightingType = JsonConvert.DeserializeObject<SightingType>(data);

You can use Json.Net and following classes (your root object is not SightingType )....

var result = JsonConvert.DeserializeObject<Response>(data);  

public class SightingType
{
    public string BrandId { get; set; }
    public List<string> DestinationUserIds { get; set; }
    public string Id { get; set; }
    public bool IsDeleted { get; set; }
    public bool IsEnabled { get; set; }
    public string Name { get; set; }
}

public class Response
{
    public object Message { get; set; }
    public int Status { get; set; }
    public int CurrentVersionNumber { get; set; }
    public List<SightingType> SightingTypes { get; set; }
}

Also see this site where you can get the class definitions for your json string

use this code to parse JSON into POCO

        //get the JSON string into 'responseText'

        // Deserialize response Message to JsonResponse
        var serializer = new JavaScriptSerializer();
        jsonResponse = serializer.Deserialize<JsonResponse>(responseText);

        // where in <> put your class 'SightingType'

you will need to add resource System.Web.Extensions.dll in order to use JavaScriptSerializer class
