C# Windows Phone 7.1 live互动程序背景图像未设置

我正在尝试更改windows phone 7.1应用程序的live互动程序的背景图像（正面和背面），但从未设置背景图像。我已将这些图像添加到项目中，并确保在Uri（）构造函数中正确指定它们的名称。我似乎无法发现这个问题。这是密码

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

    String result = "Default";
    String company = "";
    String image = "";

    //Method That Executes After Every DownloadStringAsync() Call by WebClient 
    public void wb_DownloadStringCompleted(Object sender, DownloadStringCompletedEventArgs e)
    {
        result = e.Result;

        int newCount = 1;

        // Application Tile is always the first Tile, even if it is not pinned to Start.
        ShellTile TileToFind = ShellTile.ActiveTiles.First();

        // Application should always be found
        if (TileToFind != null)
        {
            // Set the properties to update for the Application Tile.
            // Empty strings for the text values and URIs will result in the property being cleared.
            StandardTileData NewTileData = new StandardTileData
            {
                Title = "Stocks App",
                BackgroundImage = new Uri(image, UriKind.Relative),
                Count = newCount,
                BackTitle = company,
                BackBackgroundImage = new Uri(image, UriKind.Relative), //**The problem is here**
                BackContent = result
            };

            // Update the Application Tile
            TileToFind.Update(NewTileData);
        }
    }
