Exemples

L’exemple suivant montre comment obtenir un sous-dossier à partir du dossier actif en appelant la méthode GetFolderAsync. Cet exemple montre également comment obtenir un sous-dossier à partir d’un sous-dossier du dossier actif en fournissant un chemin d’accès relatif.

using Windows.Storage;
using System.Threading.Tasks;

// Get the app's local folder.
StorageFolder localFolder = ApplicationData.Current.LocalFolder;

// Create 2 levels of subfolders in the app's local folder.
string name1 = "Subfolder1";
StorageFolder subFolder1 = await localFolder.CreateFolderAsync(name1);
string name2 = "Subfolder2";
StorageFolder subFolder2 = await subFolder1.CreateFolderAsync(name2);

// Get the subfolder of the app's local folder.
string level1FolderName = "Subfolder1";
StorageFolder level1Folder = await localFolder.GetFolderAsync(level1FolderName);

// Get the subfolder of the subfolder by providing a relative path.
string level2FolderName = @"Subfolder1\Subfolder2";
StorageFolder level2Folder = await localFolder.GetFolderAsync(level2FolderName);

IAsyncAction MainPage::ExampleCoroutineAsync()
{
    // Get the app's local folder.
    Windows::Storage::StorageFolder localFolder{ Windows::Storage::ApplicationData::Current().LocalFolder() };

    // Create two levels of subfolders in the app's local folder.
    std::wstring name1{ L"Subfolder1" };
    std::wstring name2{ L"Subfolder2" };
    std::wstring level2FolderName{ L"Subfolder1\\Subfolder2" };

    Windows::Storage::StorageFolder subFolder1{ co_await localFolder.CreateFolderAsync(name1) };
    Windows::Storage::StorageFolder subFolder2{ co_await subFolder1.CreateFolderAsync(name2) };
    // Get the subfolder of the subfolder by providing a relative path.

}).then([=](StorageFolder^ subFolder2) -> task<StorageFolder^> {
