有一组学员的成绩{99,85,82,63, 60},将它们按升序排列。要增加一个学员的成绩,将它插入成绩序列,并保持升序。
using System.Collections;…………

        Console.WriteLine("请输入新增成绩:");
        int score = Convert.ToInt32(Console.ReadLine());

        Console.WriteLine("插入成绩的下标是:");
        int num = Convert.ToInt32(Console.ReadLine());


        ArrayList mylist = new ArrayList(6);

        mylist.Add(99);
        mylist.Add(85);
        mylist.Add(82);
        mylist.Add(63);
        mylist.Add(60);
        
       mylist.Insert(num, score);
        mylist.Sort();
        mylist.Reverse();
        Console.WriteLine("新的排序为:");
        foreach (var item in mylist )
        {
            Console.Write(item   + "\t");
        }

        Console.ReadKey();
