Windows Phone 8.1 Silverlight Secondary Tile isostore 错误

Question

我正在尝试将 UserControl 呈现为图像，然后将其分配给辅助磁贴并将其固定。生成的 URI 是

isostore:/Shared/ShellContent/CustomTile.jpg

但是，我收到以下错误： ExceptionObject = {System.ArgumentException：值不在预期范围内。在 Windows.UI.StartScreen.SecondaryTileVisualElements.put_Square150x150Logo(Uri 值) 在 NestWP.ActionTiles.d__1.MoveNext()

我有这段代码

        var customTile = new ActionTileControl();
        customTile.Measure(new Size(150, 150));
        customTile.Arrange(new Rect(0, 0, 150, 150));

        var bmp = new WriteableBitmap(150, 150);
        bmp.Render(customTile, null);
        bmp.Invalidate();

        const string filename = "/Shared/ShellContent/CustomTile.jpg";

        using (var isf = IsolatedStorageFile.GetUserStoreForApplication())
        {
            if (!isf.DirectoryExists("/CustomLiveTiles"))
            {
                isf.CreateDirectory("/CustomLiveTiles");
            }
            using (var stream = isf.OpenFile(filename, System.IO.FileMode.OpenOrCreate))
            {
                bmp.SaveJpeg(stream, 336, 366, 0, 100);
                stream.Close();
            }
            bool ex = isf.FileExists(filename);

            ex = ex;
        }

        string urilink = "isostore:" + filename;

        SecondaryTile secondaryTile = new SecondaryTile()
        {
            TileId = "tileid",
            DisplayName = "title",
            Arguments = "args"
        };
        //Error on the line below
        secondaryTile.VisualElements.Square150x150Logo = new Uri(urilink, UriKind.Absolute); 
        secondaryTile.VisualElements.ShowNameOnSquare150x150Logo = false;
        bool isPinned = await secondaryTile.RequestCreateAsync();

我检查了 FileExists 和 bool returns true。

如何将图像设置为辅助图块？
