How to parse the Json data in windows phone 8

c#, windows-phone-7, windows-phone-8

Solution

I propose you to build classes of your json :

public class RootObject
{
    public Response response { get; set; }
}

public class Response
{
    public int errorFlag { get; set; }
    [JsonProperty("Score Detail")]
    public JObject ScoreDetail { get; set; }
}

You can use them on the DownloadStringCompleted event :

public void webClient1_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
    RootObject root = JsonConvert.DeserializeObject<RootObject>(e.Result);
    JObject obj = root.response.ScoreDetail;
    foreach (KeyValuePair<string, JToken> pair in obj)
    {   
        string key = pair.Key; // here you got 39.
        foreach (JObject detail in pair.Value as JArray)
        {
            string date = detail["test_date"].ToString();
            string score = detail["score"].ToString();
            string total_marks = detail["total_marks"].ToString();
        }
    }
}

Hope it helps !

I am working on application in which I need parse the Json. so I am not able to get the following data in windows phone 8. ``` { "response":{ "errorFlag":0, "Score Detail":{ "39":[ { "test_date":"2013-06-28", "total_marks":"50", "score":"14" }, { "test_date":"2013-08-08", "total_marks":"20", "score":"20" } ], "40":[ { "test_date":"2013-08-08", "total_marks":"20", "score":"20" }, { "test_date":"2013-08-08", "total_marks":"30", "score":"20" }, { "test_date":"2013-08-08", "total_marks":"30", "score":"20" } ], "50":[ { "test_date":"2013-08-08", "total_marks":"30", "score":"20" } ] } } } ``` I am trying to parse the data in the following way ``` namespace testscore { public partial class MainPage : PhoneApplicationPage { public MainPage() { InitializeComponent(); Loaded += new RoutedEventHandler(Mainpage_Loaded); } void Mainpage_Loaded(object sender, RoutedEventArgs e) { WebClient webClient1 = new WebClient(); webClient1.DownloadStringCompleted += new DownloadStringCompletedEventHandler(webClient1_DownloadStringCompleted); webClient1.DownloadStringAsync(new Uri("some link")); } public void webClient1_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { var rootObject = JsonConvert.DeserializeObject<RootObject>(e.Result); MessageBox.Show(e.Result.ToString()); foreach (var res in rootObject.response.ScoreDetail) { string rs = res.Key; MessageBox.Show(rs.ToString()); ...... } } public class RootObject { public Response response { get; set; } } public class Response { public int errorFlag { get; set; } [JsonProperty("Score Detail")] public JObject ScoreDetail { get; set; } } ``` Here I am to getting key value (here it is 39) but I am not able to get the values of the score, testdate and marks. please help me in parsing these details.
