从独立存储加载大量图像时出现内存不足异常

>编辑：我一直得到 OutOfMemoryException 未处理，我认为这就是我将图像保存到独立存储的方式，我认为这是我可以解决我的问题的地方，如何在保存之前减小图像的大小？ （在保存图像的地方添加了代码）

我从独立存储中打开图像，有时超过 100 张图像，我想遍历它们的图像，但当有大约 100 到 150 张图像加载到故事板时，我会得到OutOfMemory Exception。 我如何处理此异常，我已经降低了图像的分辨率。 如何处理此异常并阻止我的应用程序崩溃？

我在这里得到这一行的例外

image.SetSource(isStoreTwo.OpenFile(projectFolder + "''MyImage" + i + ".jpg", FileMode.Open, FileAccess.Read));//images from isolated storage

这是我的代码

private void OnLoaded(object sender, RoutedEventArgs e)
    {

        IsolatedStorageFile isStoreTwo = IsolatedStorageFile.GetUserStoreForApplication();

        try
        {
            storyboard = new Storyboard
            {
                //RepeatBehavior = RepeatBehavior.Forever
            };
            var animation = new ObjectAnimationUsingKeyFrames();
            Storyboard.SetTarget(animation, projectImage);
            Storyboard.SetTargetProperty(animation, new PropertyPath("Source"));

            storyboard.Children.Add(animation);
            for (int i = 1; i <= savedCounter; i++)
            {
                BitmapImage image = new BitmapImage();
                image.SetSource(isStoreTwo.OpenFile(projectFolder + "''MyImage" + i + ".jpg", FileMode.Open, FileAccess.Read));//images from isolated storage
                var keyframe = new DiscreteObjectKeyFrame
                {
                    KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(100 * i)),
                    Value = image
                };
                animation.KeyFrames.Add(keyframe);
            }
        }
        catch (OutOfMemoryException exc)
        {
            //throw;
        }

        Resources.Add("ProjectStoryBoard", storyboard);
        storyboard.Begin();
    }

                    int bytesRead = -1;
                    // Copy the image to isolated storage. 
                    while ((bytesRead = e.ImageStream.Read(readBuffer, 0, readBuffer.Length)) > 0)
                    {
                        targetStream.Write(readBuffer, 0, bytesRead);

            }


        }
        finally
        {
            // Close image stream
            e.ImageStream.Close();
        }
    }
