Question

如何用C#.net编写五道单选题？跪求。。。。

要求用数组的形式编写程序中的题目和答案

Answer 1

1）新建一个“控制台应用程序"项目，项目名称：SingleChoiceQuestionApp

2）添加一个枚举，枚举名称：ChoiceEnum

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace SingleChoiceQuestionApp
{
    public enum ChoiceEnum
    {
        None,
        A,
        B,
        C,
        D
    }
}

3）向项目中添加一个类，类名称：SingleChoiceQuestionApp

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace SingleChoiceQuestionApp
{
    public class SingleChoiceQuestion
    {
        /// <summary>
        /// 题号
        /// </summary>
        public int QuestionId { get; set; }
        /// <summary>
        /// 单选题干
        /// </summary>
        public string Question { get; set; }
        /// <summary>
        /// 选择项A
        /// </summary>
        public string ChoiceA { get; set; }
        /// <summary>
        /// 选择项B
        /// </summary>
        public string ChoiceB { get; set; }
        /// <summary>
        /// 选择项C
        /// </summary>
        public string ChoiceC { get; set; }
        /// <summary>
        /// 选择项D 
        /// </summary>
        public string ChoiceD { get; set; }
        /// <summary>
        /// 正确选项
        /// </summary>
        public ChoiceEnum CorrectChoice { get; set; }
        /// <summary>
        /// 用户选择的项
        /// </summary>
        public ChoiceEnum UserChoice { get; set; }
        /// <summary>
        /// 判断用户选择是否正确
        /// </summary>
        public bool IsCorrect
        {
            get { return UserChoice == CorrectChoice; }
        }
        /// <summary>
        /// 显示
        /// </summary>
        public void ShowQuestion()
        {
            Console.WriteLine("[{0}].{1}", QuestionId, Question);
            Console.WriteLine("A.{0,-30} B.{1,-30}", ChoiceA, ChoiceB);
            Console.WriteLine("C.{0,-30} D.{1,-30}", ChoiceC, ChoiceD);
            Console.Write("正确的选择是:");
            ConsoleKeyInfo c = Console.ReadKey();
            switch (c.Key)
            {
                case ConsoleKey.A :
                    UserChoice = ChoiceEnum.A;
                    break;
                case ConsoleKey.B:
                    UserChoice = ChoiceEnum.B;
                    break;
                case ConsoleKey.C:
                    UserChoice = ChoiceEnum.C;
                    break;
                case ConsoleKey.D:
                    UserChoice = ChoiceEnum.C;
                    break;
                default:
                    UserChoice = ChoiceEnum.None;
                    break;
            }
            Console.WriteLine();
            if (IsCorrect)
            {
                Console.WriteLine("恭喜你，回答正确！");
            }
            else
            {
                Console.WriteLine("回答错误，继续努力！");
            }
        }
    }
}

4）主程序（只给出了3个题目，可以自行修改、扩充）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace SingleChoiceQuestionApp
{
    class Program
    {
        static void Main(string[] args)
        {
            SingleChoiceQuestion t1 = new SingleChoiceQuestion();
            t1.QuestionId = 1;
            t1.Question = "产自热带的水果是";
            t1.ChoiceA = "苹果";
            t1.ChoiceB = "栗子";
            t1.ChoiceC = "菠萝";
            t1.ChoiceD = "鸭梨";
            t1.CorrectChoice = ChoiceEnum.C;
            t1.ShowQuestion();

            Console.WriteLine("-------------");

            SingleChoiceQuestion t2 = new SingleChoiceQuestion();
            t2.QuestionId = 2;
            t2.Question = "企鹅生活在";
            t2.ChoiceA = "南极";
            t2.ChoiceB = "北极";
            t2.ChoiceC = "热带";
            t2.ChoiceD = "温带";
            t2.CorrectChoice = ChoiceEnum.A;
            t2.ShowQuestion();

            Console.WriteLine("-------------");

            SingleChoiceQuestion t3 = new SingleChoiceQuestion();
            t3.QuestionId = 3;
            t3.Question = "在导体中可自由移动的是";
            t3.ChoiceA = "电子";
            t3.ChoiceB = "中子";
            t3.ChoiceC = "质子";
            t3.ChoiceD = "共价键";
            t3.CorrectChoice = ChoiceEnum.A;
            t3.ShowQuestion();

            Console.WriteLine();
            Console.WriteLine("考试结束，按任意键退出");
            Console.ReadKey();
        }
    }
}

Answer 2

先写一个题目类，再写一个答案类，题目类关联答案类，然后数组里面放题目类作为元素就好了

Answer 3

随便找本关于C#的书，应该都有。
