M:Windows.Storage.StorageLibrary.AreFolderSuggestionsAvailableAsync |
winrt method |
Determines if there are suggestions for adding existing folders with content to the StorageLibrary.
True if there are folder suggestions; False otherwise
If this feature is not supported on your version of Windows, the method will return false.
This example demonstrates how to determine whether there are any suggested folders with content that can be added to your Pictures library.
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
}
}Note
Don't forget to include the picturesLibrary capability in your app's package manifest. For more information on Capabilities in the manifest, see App capability declarations.
