c# 大批量用戶訪問數據庫報錯

報錯信息：There is already an open DataReader associated with this Connection which must be closed first

緩解的方案：在實例化database的時候利用線程獨立實例化，每個線程一個單獨的database實例

 

        [ThreadStatic]
        private static Database _threadInstance = null;

        protected Database DB = CreateDatabase();

        public static Database CreateDatabase()
        {
            if (_threadInstance == null)
            {
                _threadInstance = new Database(connectionStr);
            }
            return _threadInstance;
        }
