 private DataManager()
        {
            this.dicCurrencyData = new Dictionary<int, CurrencyData>();
            this.dicItemData =  new Dictionary<int, ItemData>();
            this.dicHeroData = new Dictionary<int, HeroData>();
        }

            if (DataManager.singleTone == null)
            {
                DataManager.singleTone = new DataManager();
