篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了C#传智:几个练习题和飞行棋(第八天)相关的知识，希望对你有一定的参考价值。
一、练习题
1.取字串数组中最长的元素。
private static void Main(string[] args)
string[] str = "马龙", "迈克尔乔丹", "雷吉米勒", "蒂姆邓肯", "科比布莱恩特" ;
Console.WriteLine(GetSeri(str));
Console.ReadKey();
public static string GetSeri(string[] str)
int j = 0;
for (int i = 0; i < str.Length; i++)
if (str[i].Length > j)
j = i;
return str[j];
2.取整数数组中的平均值，保留两位小数
private static void Main(string[] args)
int[] intA = 2, 3, 4, 5, 6, 7 ;
double avg = GetAvg(intA);
Console.WriteLine("0:0.00", avg);//4.50
Console.WriteLine(avg.ToString("0.00"));//4.50
Console.WriteLine(Convert.ToDouble(avg.ToString("0.00")));//4.5
Console.ReadKey();
public static double GetAvg(int[] intB)
double sum = 0;//提升为doulbe
for (int i = 0; i < intB.Length; i++)
sum += intB[i];
return 1.00 * sum / intB.Length;
3.方法A判断输入是否为质数，方法B要求只能输入数字，否则一直输入
private static void Main(string[] args)
int num = GetNum();
if (GetPrime(num)) Console.WriteLine("是质数");
else Console.WriteLine("不是质数");
Console.ReadKey();
public static int GetNum()
int a;
while (true)
Console.WriteLine("请输入一个正整数");
try
a = Convert.ToInt32(Console.ReadLine());
break;
catch
Console.WriteLine("不是数字，请重新输入！");
return a;
public static bool GetPrime(int a)
if (a <= 2) return false;
else
for (int i = 2; i <= a / 2; i++)
if (a % i == 0) return false;
return true;
4.输入分数，判断优良等级别
private static void Main(string[] args)
while (true)
try
Console.WriteLine("请输入分数(大于0)：");
int num = Convert.ToInt32(Console.ReadLine());
if (num >= 0)
Console.WriteLine(GetLevel(num));
break;
catch
Console.WriteLine("不是数字请重输入!");
Console.ReadKey();
public static string GetLevel(int score)
switch (score / 10)
case 10:
case 9: return "优";
case 8: return "良";
case 7: return "中";
case 6: return "差";
default: return "不及格";
5.数组反转。注意参数不加ref也可传回到实参
private static void Main(string[] args)
string[] str = "中国", "美国", "巴西", "澳大利亚", "加拿大" ;
//str = str.Reverse().ToArray();
//Array.Reverse(str);
GetReverse(str);
for (int i = 0; i < str.Length; i++)
Console.WriteLine(str[i]);
Console.ReadKey();
public static void GetReverse(string[] str)
//参数不加ref，对数组一样可以影响实参
for (int i = 0; i < str.Length / 2; i++)
string temp = str[i];
str[i] = str[str.Length - 1 - i];
str[str.Length - 1 - i] = temp;
6.返回圆的周长与面积。
private static void Main(string[] args)
double r = 5, peri, area;
area = GetParams(r, out peri);//若未定义也可out double peri
Console.WriteLine("周长为0,面积为1.", peri, area);
Console.ReadKey();
public static double GetParams(double r, out double p)
//out参数可前可后。
p = 2 * 3.14 * r;
return 3.14 * r * r;
二、飞行棋
1.规则
蛇形地图，两人轮流掷骰，谁达终点即胜。
图例：幸运轮盘：◎ 地雷：☆ 暂停：△ 时空隧道：◆
游戏规则：
如果玩家A踩到玩家B，玩家B退6格
如果玩家踩中地雷。退6格
如果玩家踩进时空隧道，进10格
如果玩家踩到幸运轮盘， 1 交换位置，2 轰炸对方（使对方退6格）
如果玩家踩到了暂停，暂停一个回合
如果玩家踩到了方块，走到当前位置，什么都不发生
2、程序
internal class Program
// 普通□ 幸运轮盘：◎ 地雷：★ 暂停：▲ 时空隧道：卐
public static int[] Maps = new int[100]; //地图
public static int[] playerPos = new int[2]; //玩家坐标
public static string[] playerNames = new string[2];//玩家name
public static bool[] b = new bool[2];//暂停，0，1
private static void Main(string[] args)
GameStart();
InitMap();
DrawMap();
InputPlayer();//输入玩家名字
Console.Clear();
InitMap();
DrawMap();
while (playerPos[0] < 99 && playerPos[1] < 99)
if (b[0] == false) PlayGame(0);
else b[0] = false;
if (b[1] == false) PlayGame(1);
else b[1] = false;
Win();
Console.ReadKey();
public static void Win()
if (playerPos[0] >= 99)
Console.WriteLine("玩家0取得了胜利！！", playerNames[0]);
else
Console.WriteLine("玩家0取得了胜利！！", playerNames[1]);
public static void PlayGame(int n)
Random r = new Random();
int step = r.Next(1, 7);//[1,7)
Console.WriteLine("玩家0按任意键开始掷骰子:", playerNames[n]);
Console.ReadKey(true);//不显示按键激活
Console.WriteLine(" 掷出了0,准备前行0步", step);
playerPos[n] += step;
Console.ReadKey(true);
if (playerPos[n] == playerPos[1 - n])//踩中另一玩家退6格
Console.WriteLine(" 玩家0被踩中退6格", playerNames[1 - n]);
playerPos[1 - n] -= 6;
else//是否关卡
ChangePos();
switch (Maps[playerPos[n]])
case 0:
Console.WriteLine(" 玩家0踩到了方块，安全.", playerNames[n]);
break;
case 1:
Console.WriteLine(" 玩家0踩到了轮盘，选择1--交换位置,2--轰炸对方退6格", playerNames[n]);
string sel = Console.ReadLine();
while (sel != "1" && sel != "2")
if (sel == "1")
Console.WriteLine(" 你选择了交换位置");
int temp = playerPos[n];
playerPos[n] = playerPos[1 - n];
playerPos[1 - n] = temp;
Console.WriteLine(" 位置交换完成.");
else if (sel == "2")
playerPos[1 - n] -= 6;
Console.WriteLine(" 玩家0退6格完成.", playerNames[1 - n]);
else
Console.WriteLine(" 无效输入，请重新输入1--交换位置，2--轰炸对方退6格");
sel = Console.ReadLine();
break;
case 2:
Console.WriteLine(" 玩家0踩到了地雷退6格", playerNames[n]);
playerPos[n] -= 6;
break;
case 3:
Console.WriteLine(" 玩家0踩到了暂停，暂停一回合。", playerNames[n]);
b[n] = true;
break;
case 4:
Console.WriteLine(" 玩家0踩到了时空隧道，进10格", playerNames[n]);
playerPos[n] += 10;
break;
