code:

　　  private const string FolderName = "temp1/NewFolder";
        private const string FileName = FolderName + "/file.data";
        private const string Setting1 = "Setting1";

        void MainPage_Loaded(object sender, RoutedEventArgs e)
        {
            using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication())
            {
                file.CreateDirectory(FolderName);
                
                string[] array = file.GetDirectoryNames("temp1/");
            }
        }

7.0版本中 array.Length==1 ; 但是在7.1版本中array.Length==0

貌似在7.0支持的在7.1里面倒是不支持了

正在寻找另外的方法解决7.1版本中的文件和文件夹问题

望各位不吝赐教。。。谢谢！！
