除了第8点看不懂外

其他答案如下

    public class Person
    {
        public string Name;
        public int Age;
        /// <summary>
        /// 构造函数
        /// </summary>
        public Person(string name,int age)
        {
            Name = name;
            Age = age;
        }

        public virtual void showInfo()
        {
            Console.WriteLine("姓名："+Name);
            Console.WriteLine("年龄：" + Age.ToString());
            Console.ReadLine();
        }

    }

    public class Student : Person
    {
        public string School;
        public string Num;

        public Student(string name, int age,string school,string num) : base(name, age)
        {
            Name = name;
            Age = age;
            School = school;
            Num = num;
        }

        public void Hello()
        {
            Console.WriteLine("Hello"+ School + Name);
            Console.WriteLine();
        }

        public override void showInfo()
        {
            Console.WriteLine("学校：" + School);
            Console.WriteLine("学号：" + Num);
            Console.WriteLine("姓名：" + Name);
            Console.WriteLine("年龄：" + Age.ToString());
            Console.ReadLine();
        }
    }

    static void Main()
    {
        Person p1 = new Person("楼主", 20);
        p1.showInfo();

        Student s1 = new Student("如花", 30, "断罪小学", "170505");
        s1.showInfo();
    }
