如何解决异常，在IsolatedFileStream上不允许操作？

调试之后，我意识到某条线没有被读取，它被跳过了捕获部分。我正在从Windows Phone 7中的照片样本中读取图像，并将其上传到skydrive。有人可以指导我如何解决这个问题吗？感谢。

public BitmapImage fileName { get; set; }

private void GetImages()
{
    MediaLibrary mediaLibrary = new MediaLibrary();
    var pictures = mediaLibrary.Pictures;

    foreach (var picture in pictures)
    {
        BitmapImage image = new BitmapImage();
        image.SetSource(picture.GetImage());              

        MediaImage mediaImage = new MediaImage();
        mediaImage.fileName = image;
        UploadFile(mediaImage, picture.Name);                
    }
}

public void UploadFile(MediaImage image, string filepath)
{
   if (skyDriveFolderID != string.Empty) 
   {
     this.client.UploadCompleted += new EventHandler<LiveOperationCompletedEventArgs>(ISFile_UploadCompleted);
     infoTextBlock.Text = "Uploading backup...";
     dateTextBlock.Text = "";

     try
     {
        using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
        {
           // error occurs HERE
           IsolatedStorageFileStream readStream = myIsolatedStorage.OpenFile(filepath, FileMode.Open, FileAccess.Read);

           readStream.Close();
           this.client.UploadAsync(skyDriveFolderID, filepath, true, readStream, null)
        }
     }

你确定那里会发生错误吗？我可以在阅读之前关闭流。所以可能是你错误的错误。

另外，您是否确定，具有该确切名称的文件存在于隔离存储中？
