如何將照相機捕獲的照片保存在圖片庫中

Question

我使用下面的代碼捕獲照片，但不知道如何將其保存在圖片庫或圖片庫中的文件夾中。希望你對此有所幫助。

CameraCaptureUI camera = new CameraCaptureUI(); 
camera.PhotoSettings.CroppedAspectRatio = new Size(16, 9); 
StorageFile photo = await camera.CaptureFileAsync(CameraCaptureUIMode.Photo); 


if (photo != null) 
{ 
    BitmapImage bmp = new BitmapImage(); 
    IRandomAccessStream stream = await photo.OpenAsync(FileAccessMode.Read); 
    bmp.SetSource(stream); 
    ImageSource.Source = bmp; 
    ImageSource.Visibility = Visibility.Visible; 

    StorageFolder storageFolder = KnownFolders.PicturesLibrary; 

??? not sure : 
    var imagefile = await KnownFolders.PicturesLibrary.CreateFileAsync("MyPhoto.jpeg", CreationCollisionOption.ReplaceExisting); 

    photo.CopyAsync(storageFolder,imagefile); 

    }

你在這裏。您必須在清單中設置相機和圖片庫訪問功能。

CameraCaptureUI camera = new CameraCaptureUI(); 
camera.PhotoSettings.CroppedAspectRatio = new Size(16, 9); 
StorageFile photo = await camera.CaptureFileAsync(CameraCaptureUIMode.Photo); 

//By default the photo will be stored at location 
//%localappdata%\Packages\APP_PACKAGE_ID\TempState 

if (photo != null) 
{ 
    //await photo.MoveAsync(KnownFolders.PicturesLibrary); 
    //OR 
    await photo.MoveAsync(KnownFolders.PicturesLibrary, "DesiredPhotoName" + photo.FileType, NameCollisionOption.GenerateUniqueName); 
}
