在WinRT上复制文件夹

Question

现在,我只知道如何使用以下方法复制文件:

IStorageFolder dir = Windows.Storage.ApplicationData.Current.LocalFolder;

IStorageFile file = await StorageFile.GetFileFromApplicationUriAsync(
    new Uri("ms-appx:///file.txt"));

await file.CopyAsync(dir, "file.txt");

当我尝试复制文件夹和里面的所有内容时,我找不到CopyAsync上面的API .

是否可以复制文件夹和WinRT中的所有内容？

上面的代码不满足我(太具体),我制作了我自己的通用代码,所以我想可以分享它:

public static async Task CopyFolderAsync(StorageFolder source, StorageFolder destinationContainer, string desiredName = null)
    {
        StorageFolder destinationFolder = null;
            destinationFolder = await destinationContainer.CreateFolderAsync(
                desiredName ?? source.Name, CreationCollisionOption.ReplaceExisting);

        foreach (var file in await source.GetFilesAsync())
        {
            await file.CopyAsync(destinationFolder, file.Name, NameCollisionOption.ReplaceExisting);
        }
        foreach (var folder in await source.GetFoldersAsync())
        {
            await CopyFolderAsync(folder, destinationFolder);
        }
    }
