                var cmd = new System.Data.SqlClient.SqlCommand("insert into xxxtable(name,phone)values('" + name + "','" + phone + "')",conn);

            public static IDataHelp Create()
            {
                var d =(int) DateTime.Now.DayOfWeek;
                if (d == 6 || d == 0) return new FileHelp();
                return new SqlHelp();
            }
        }
        static void Main(string[] args)
        { 
            var help = DataHelpFactory.Create();
            
            help.Insert("test", "13900001111");

            Console.ReadKey();
        }
    }
}

思路：
1.先定义对应的动物的类，创建动物对象；
2.把所有动物对象放在hashmap里面，名字为key;
3.通过输入的名字把对应动物对象取出来，并显示在页面。
