需要帮助修复异常

Question

有人可以解释以下 2 个崩溃异常吗！我不明白如何解决它们 -

具体代码段如下所示 -

private void SaveButton_Click(object sender, EventArgs e)
        {
            WriteableBitmap wb = new WriteableBitmap(SelectedImage.TransformedImage);
            MemoryStream targetStream = new MemoryStream();  
            wb.SaveJpeg(targetStream, wb.PixelWidth, wb.PixelHeight, 0, 100);
            if (targetStream != null)
            {
                targetStream.Seek(0, 0); // necessary to initiate the stream correctly before save
                try
                {
                    MediaLibrary ml = new MediaLibrary();
                    Picture p = ml.SavePicture(Guid.NewGuid().ToString(), targetStream);
                    MessageBox.Show("Saved Successfully to your Media Library!");
                }
                catch (Exception ex)
                {
                    MessageBox.Show("Error - " + ex.Message);
                }
            }
            else
            {
                MessageBox.Show("Unexpected error!");
            }
        }

这段代码是 ->

        {
            base.OnNavigatedTo(e);
            if (e.NavigationMode == NavigationMode.New)
            {
                // Get a dictionary of query string keys and values.
                IDictionary<string, string> queryStrings = this.NavigationContext.QueryString;
                // Ensure that there is at least one key in the query string, and check whether the "token" key is present.
                if (queryStrings.ContainsKey("token"))
                {
                    // Retrieve the picture from the media library using the token passed to the application.
                    MediaLibrary library = new MediaLibrary();
                    Picture picture = library.GetPictureFromToken(queryStrings["token"]);
                    // Create a WriteableBitmap object and add it to the Image control Source property.
                    BitmapImage bitmap = new BitmapImage();
                    bitmap.CreateOptions = BitmapCreateOptions.None;
                    bitmap.SetSource(picture.GetImage());
                    //WriteableBitmap picLibraryImage = new WriteableBitmap(bitmap);
                    //retrievePic.Source = picLibraryImage;
                    SelectedImage.OriginalImage = bitmap;
                    navigateCompleted(null, null);
                    //NavigationService.Navigate(HelperClass.Constants.TransformPageUri);
                    //NavigationService.Navigated -= new NavigatedEventHandler(navigateCompleted);
                }
            }

Answer 1

请添加一些代码，但第一个异常看起来保存按钮的单击事件中存在错误：

8 PhotoRotator.TransformedImage.SaveButton_Click 504

尝试逐步调试它。 并给我们一些代码
