windows8 Camera和CaptureUI

CameraCaptureUI樣本這個樣本示範了如何使用Windows.Media.Capture。 CameraCaptureUI API,這將顯示一個UI用於捕獲全屏照片或視頻。 async void Scenario1Button_Click(object sender, RoutedEventArgs e)
        {
            try
            {
                CameraCaptureUI dialog = new CameraCaptureUI();
                Size aspectRatio = new Size(16, 9);
                dialog.PhotoSettings.CroppedAspectRatio = aspectRatio;

                StorageFile file = await dialog.CaptureFileAsync(CameraCaptureUIMode.Photo);
                if (file != null)
                {
                    Scenario1OutputText.Text = "";
                    BitmapImage bitmapImage = new BitmapImage();
                    using(IRandomAccessStream fileStream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read))
                    {
                        bitmapImage.SetSource(fileStream);
                    }
                    Scenario1Image.Source = bitmapImage;
                    Scenario1ResetButton.Visibility = Visibility.Visible;
                    photoFile = file.Path;
                }
                else
                {
                    Scenario1OutputText.Text = "No photo captured.";
                }
            }
            catch (Exception ex)
            {
                Scenario1OutputText.Text = ex.Message;
            }
