C#学生成绩管理（控制台程序）

Question

C#学生成绩管理（控制台程序）功能：录入学生基本信息 如姓名，学号，各科成绩，输入各科成绩后就求各科成绩总分和平均分，做过的朋友帮帮忙，记得加上注释，偶是新手，谢谢。

Answer 1

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;namespace Students
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.Write("请输入学生姓名：");
            string Name = Console.ReadLine().ToString();
            Console.Write("请输入学号：");
            uint StudentID = uint.Parse(Console.ReadLine());
            Console.Write("请输入一共要考几科");
            uint SubjectsNO = uint.Parse(Console.ReadLine());
            Console.WriteLine("请输入各科名称：");
            string[] Subjects = new string[SubjectsNO];//装成绩的数组
            for(int i=0;i<Subjects.Length;i++)
            {
                Subjects[i] = Console.ReadLine().ToString();
            }
            Console.Write("请输入各科分数：");
            int[] Fractions= new int[SubjectsNO];//装分数的数组
            for (int i = 0; i < Subjects.Length; i++)
            {
                    Console.WriteLine("{0}", Subjects[i]);
                    Fractions[i] = int.Parse(Console.ReadLine());
            }
            Console.WriteLine("您输入的信息如下：");
            Console.WriteLine("姓名：{0}",Name);
            Console.WriteLine("学号：{0}",StudentID);
            Console.WriteLine("一共考试科目是{0},科目和分数如下：",SubjectsNO);
            for (int i = 0; i < Subjects.Length; i++)//显示科目和成绩
            {
                Console.WriteLine("{0}：{1}",Subjects[i],Fractions[i]);
            }
            Console.WriteLine("分数总和是：{0}", Fractions.Sum());//求和
            Console.WriteLine("平均分数是：{0}", Fractions.Average());//求平均数
        }
    }
}学程序要动手做。

Answer 2

你自己都把程序说的很明白了嘛..
为什么自己会写不出来呐...
多注意点思路..
OOP要学好
