            SQLiteDataAdapter sqLiteDataAdapter = new SQLiteDataAdapter
            {
                SelectCommand = sqLiteCmd
            };
            DataSet dataSet = new DataSet();
            sqLiteDataAdapter.Fill(dataSet);
            sqLiteConn.Close();
            foreach (DataRow item in dataSet.Tables[0].Rows)
            {
                Console.WriteLine($"db_name：{item.ItemArray[2].ToString()}，hash_value：{item.ItemArray[3].ToString()}");
            }
            //string ss =$"编号：{dataSet.Tables[0].Rows[0].ItemArray[2].ToString()}，姓名：{dataSet.Tables[0].Rows[0].ItemArray[3].ToString()}";            
            //return ss;
        }
    }
}
