c# 系统随机产生一个0~100数，然后不断提示用户猜数字。代码

Answer 1

控制台应用程序，超旋的．你的要求比较简单好实现．
你看看人家怎么写的吧是4位数的．
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
namespace NumGuess
{
class Guess
{
ColorInput colorText = new ColorInput(); //控制台彩色输出类
private string choose = null; //对于 菜单的 选择
private int[] random = new int[4]; //随机产生的 一个 4位数
private int[] guess = new int[4]; //存储 用户 猜测的 4位数
private bool again = false; //是否是 继续游戏 而不是开始新游戏

public Guess()
{
}

//显示游戏开始的一些信息
void Game()
{
colorText.SetTextColor((int) ColorInput.Foreground.Blue); //设置控制台输出字符的颜色
Console.WriteLine("\t\t\t\t猜数字游戏\n\n");
colorText.SetTextColor((int) ColorInput.Foreground.Green);
Console.Write("\t游戏说明：游戏开始，您要猜随机产生的一个四位数，"
+ "数字的");
colorText.SetTextColor((int) ColorInput.Foreground.Red);
Console.Write("位置");
colorText.SetTextColor((int) ColorInput.Foreground.Green);
Console.Write("和");
colorText.SetTextColor((int) ColorInput.Foreground.Red);
Console.Write("大小");
colorText.SetTextColor((int) ColorInput.Foreground.Green);
Console.Write("都要猜对才算赢哦，有点像彩票哦，不过您每次只有");
colorText.SetTextColor((int) ColorInput.Foreground.Red);
Console.Write("10");
colorText.SetTextColor((int) ColorInput.Foreground.Green);
Console.Write("次机会哦~~!!!\n");
colorText.SetTextColor((int) ColorInput.Foreground.Purple);
Console.WriteLine("\t\t\t\t\t\t\t----By H_Q");

colorText.SetTextColor((int) ColorInput.Foreground.White);
Console.WriteLine("\t\t\t\t菜单(请选择)");
Console.WriteLine("\t\t\t\t 1.开始");
Console.WriteLine("\t\t\t\t 0.退出");
Init();
}// Game

void Init()
{

//判断 用户的 选择

//接受用户的 输入的 数字
void Input()

bool isFormat = false;
//若输入的不正确 循环要求用户输入
do

//注： IndexOf(string) 此方法 从 string 中查找相同字符 若没找到 返回-1

Answer 5

有一个Random的静态类啊，随机数很好产生，猜数字是什么意思？
