照片中的图片保存至IsolatedStorage:

      private void btnCamera_Click(object sender, RoutedEventArgs e)
        {
            CameraCaptureTask camera = new CameraCaptureTask();
            camera.Completed += new EventHandler<PhotoResult>(camera_Completed);
            camera.Show();
        }
        void camera_Completed(object sender, PhotoResult e)
        {
            if (e.ChosenPhoto != null)
            {
                BitmapImage image = new BitmapImage();
                image.SetSource(e.ChosenPhoto);
                imgCamera.Source = image;  

                using (IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication())
                {
                    WriteableBitmap wb = new WriteableBitmap(image);
                    using (Stream stream = storage.OpenFile("images/img.jpg", FileMode.Create))
                    {
                        System.Windows.Media.Imaging.Extensions.SaveJpeg(wb, stream, wb.PixelWidth, wb.PixelHeight, 0, 100);
                    }
                }

            }
        }

       读取IsolatedStorage中的图片:

       private void btnRead_Click(object sender, RoutedEventArgs e)
        {
            BitmapImage bi = new BitmapImage();
            using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
            {
                using (IsolatedStorageFileStream fileStream = myIsolatedStorage.OpenFile("Images/sun.png", FileMode.Open, FileAccess.Read))
                {
                    bi.SetSource(fileStream);
                    this.imgPic.Height = bi.PixelHeight;
                    this.imgPic.Width = bi.PixelWidth;
                }
            }
            this.imgPic.Source = bi;
        }
