我正在尝试使用Web服务读取数据并将其显示在如下所示的成本化的lisBox上,但它不起作用."当我进行调试时,我的手机应用程序屏幕没有显示任何列表"

XAML代码:

 <ListBox Height="500" HorizontalAlignment="Left" 
         Margin="8,47,0,0" 
         Name="friendsBox" VerticalAlignment="Top" Width="440">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <Image Height="100" Width="100" 
                       VerticalAlignment="Top" Margin="0,10,8,0"
                       Source="{Binding Photo}"/>
                <StackPanel Orientation="Vertical">
                    <TextBlock Text="{Binding Nom}" FontSize="28" TextWrapping="Wrap" Style="{StaticResource PhoneTextAccentStyle}"/>
                    <TextBlock   />
                </StackPanel>
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

C#代码:

void friends_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
    if (e.Error == null)
    {
        ListBoxItem areaItem = null;
        StringReader stream = new StringReader(e.Result);
        XmlReader reader = XmlReader.Create(stream);

        string Nom = String.Empty;
        string Photo = String.Empty;

        while (reader.Read())
        {
            if (reader.NodeType == XmlNodeType.Element)
            {

                if (reader.Name == …
