添加语句，使得能够选择性输出信息。例如，输入book和mage，跳出不同的信息。这里是选择输出书的属性和出版社的属性

    class catalogue //基类
    {
        public string title;
        public string writer;

        public void print_V()

            Console.WriteLine("标题是什么？");
            this.title = Console.ReadLine();
            Console.WriteLine("作者是谁？");
            this.writer = Console.ReadLine();
            Console.WriteLine("发布时间是多少？");
            this.date = Console.ReadLine();
        }
        public void display()
        {
            Console.WriteLine();
            Console.WriteLine("标题是{0}", this.title);
            Console.WriteLine("作者是{0}", this.writer);
            Console.WriteLine("发布日期是{0}", this.date);
        }
        class articles : catalogue

            }

            static void Main(string[] args)
            {
                articles art = new articles();
                art.print_A();
                art.displayskill();


                books bo = new books();
                bo.print_B();
                bo.displayskilled();
            }

        }


    }
}

好难

设置一个flag,就行啦。呵呵

在哪边设置一个flag??

不要乱发。。这个。

flag,如何在主函数中添加呢？请大神赐教

我将主函数改成这样，当输入articles时，出现错误了。为什么 ？输入books时却没有。。

                string Flag;
                Console.WriteLine("请输入books或者articles");
                Flag = Console.ReadLine();
                if  (Flag == "articles")
                {
                    articles art = new articles();
                    art.print_A();
                    art.displayskill();
                }
                if  (Flag == "books")
                {
                    books bo = new books();
                    bo.print_B();
                    bo.displayskilled();
                }
