예제

이 예제에서는 사진 라이브러리에 추가할 수 있는 콘텐츠가 포함된 제안된 폴더가 있는지 여부를 확인하는 방법을 보여 줍니다.

private async Task<StorageLibrary> SetupPicturesLibraryAsync()
{
    if (this.picturesLibrary == null)
    {
        this.picturesLibrary = await StorageLibrary.GetLibraryAsync(KnownLibraryId.Pictures);
        this.picturesLibrary.DefinitionChanged += PicturesLibrary_DefinitionChanged;
    }
    return this.picturesLibrary;
}

private async void CheckForFolderSuggestions_Clicked(object sender, RoutedEventArgs e)
{
    var library = await SetupPicturesLibraryAsync();

    if (await library.AreFolderSuggestionsAvailableAsync())
    {
        // There are new folders that could be added to the library.
        // Prompt the user to add one or more of them. 

        // Note that the RequestAddFolderAsync method returns only one folder.
        // If the user adds multiple folders, only one will be returned.
        // In this example, to keep track of all the added folders, the app can subscribe to the
        // StorageLibrary.DefinitionChanged event by awaiting library.RequestAddFolderAsync();

        // Launch the folder suggestion dialog
        var folder = await library.RequestAddFolderAsync(); 
    }
}

private void PicturesLibrary_DefinitionChanged(StorageLibrary sender, object args)
{
    foreach (StorageFolder folder in sender.Folders)
    {
        // Do something with every folder in the library
    }
}
