Deserializing a JSON array to LongListSelector Windows Phone 8

Question

How can i deserialize this jsonx variable and put it on a longlistselector on windows phone?

Currently i can only echo one string with messagebox. i need key-value sets on a longlistselector.

edit: this is my answer http://pastebin.com/CcADHaab

here is my code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Navigation;
using Microsoft.Phone.Controls;
using Microsoft.Phone.Shell;
using PhoneApp5.Resources;
using Newtonsoft.Json;

namespace PhoneApp5
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();



            string json = @"{
  'Email': 'james@example.com',
  'Active': true,
  'CreatedDate': '2013-01-20T00:00:00Z'
}";

            string jsonx = @"{
  'Table1': [
    {
      'id': 0,
      'item': 'item 0'
    },
    {
      'id': 1,
      'item': 'item 1'
    }
  ]
}";



            Account account = JsonConvert.DeserializeObject<Account>(json);

           // Console.WriteLine(account.Email);
            // james@example.com
            MessageBox.Show(account.Email);

            list.ItemsSource = new BookList();

        }



        }
    public class BookList : List<Account>
    {
        public BookList()
        {


        }


    }
        public class Account
        {
            public string Email { get; set; }
            public bool Active { get; set; }
            public DateTime CreatedDate { get; set; }
           // public IList<string> Roles { get; set; }

        }

Answer 1

You need a class to represent your json:

public class MyClass
{
   public string Id { get; set; }
   public string Item { get; set; }
}

Set a ObservableCollection property in your Form:

public ObservableCollection<MyClass> MyClassCollection { get; set; }

and then set the MyClassCollection property to your Deserialized json

MyClassCollection = JsonConvert.DeserializeObject<ObservableCollection<MyClass>>(e.Result);

That way you're binding your class list to the LongListSelector Control in your XAML:

        <phone:LongListSelector Name="list" ItemsSource="{Binding MyClassCollection}">
            <phone:LongListSelector.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <TextBlock Text="{Binding id}" />
                        <TextBlock Text=" ( " />
                        <TextBlock Text="{Binding item}" FontStyle="Italic" />
                        <TextBlock Text=" )" />
                    </StackPanel>
                </DataTemplate>
            </phone:LongListSelector.ItemTemplate>

That should work.
