Windows phone 7 如何使用C代码在Windwos Phone 7中解析和显示Json数据

这是我的C代码。我能够计算var rootObject=JsonConvert.DeserializeObjecte.Result的项目数；包含响应，但我无法打印数据。请帮助我如何打印。请至少打印一个项目，以便我能理解

您必须在XAML中准备UI并从codebehind设置数据绑定

<ListBox Name="ListBoxNews" Margin="10,0,30,0" Height="486" Width="404" FontSize="20">
            <ListBox.ItemTemplate>
                <DataTemplate >
                    <StackPanel Margin="10,0,10,8">
                        <TextBlock Text="{Binding news_date}" TextWrapping="Wrap" FontSize="18" />
                        <TextBlock Text="{Binding news_title}" TextWrapping="Wrap" FontSize="24" /> 
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

xaml代码示例：

   void myButton_Click(object sender, RoutedEventArgs e)
        {

            WebClient webClient = new WebClient();
            webClient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(webClient_DownloadStringCompleted);

            webClient.DownloadStringAsync(new Uri("http://www.taxmann.com/TaxmannWhatsnewService/mobileservice.aspx?service=topstories"));
        }

   void webClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
        {
            var rootObject = JsonConvert.DeserializeObject<List<Contacts>>(e.Result);         
        }

        public class Contacts
        {
            public string news_id { get; set; }
            public string news_title { get; set; }
            public string website_link { get; set; }
            public string imagepath { get; set; }
            public string news_date { get; set; }
            public string news_detail_description { get; set; }

        }

以及从codebehind进行数据绑定

<ListBox Name="ListBoxNews" Margin="10,0,30,0" Height="486" Width="404" FontSize="20">
            <ListBox.ItemTemplate>
                <DataTemplate >
                    <StackPanel Margin="10,0,10,8">
                        <TextBlock Text="{Binding news_date}" TextWrapping="Wrap" FontSize="18" />
                        <TextBlock Text="{Binding news_title}" TextWrapping="Wrap" FontSize="24" /> 
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
