如果你想要实现删除文件夹的内容，那么这样的递归方法就可以了：

public static async Task DeleteFolderContentsAsync(StorageFolder folder,
   StorageDeleteOption option)
{
   // Try to delete all files
   var files = await folder.GetFilesAsync();
   foreach (var file in files)
   {
      await file.DeleteAsync(option);
   }

   // Iterate through all subfolders
   var subFolders = await folder.GetFoldersAsync();
   foreach (var subFolder in subFolders)
   {
      // Delete the contents
      await DeleteFolderContentsAsync(subFolder, option);

      // Delete the subfolder
      await subFolder.DeleteAsync(option);
   }
}
