今天修改了以前写的猜数字游戏的代码,之前的代码一大坨,可读性太差,所以做了些修改,优化了结构,也正好消除了之前的一个问题。感兴趣的朋友可以看看,以下是代码部分:
1 using System; 2 using System.Linq; 3 4 namespace 猜数字游戏_0_100_ 5 { 6 class Program 7 { 8 static void Main(string[] args) 9 { 10 GuessMethod(0, 100); 11 12 PlayAgain(); 13 } 14 15 private static void GuessMethod(int lowerLimit, int upperLimit) 16 { 17 Random rand = new Random(); 18 int randomNumber = rand.Next(lowerLimit, upperLimit); 19 20 int guessTimes = 1; 21 22 Console.WriteLine("欢迎来到猜数字游戏,数字范围为 {0,-2} - {1,-2},按Enter键开始", lowerLimit, upperLimit); 23 Console.ReadLine(); 24 25 for (guessTimes = 1; guessTimes <= 10; guessTimes++) 26 { 27 int guessNumber = InputNumber(guessTimes, lowerLimit, upperLimit); 28 29 if (guessNumber == randomNumber) 30 { 31 Console.WriteLine("恭喜你猜对了!正确的答案为{0}!\r\n", randomNumber); 32 break; 33 } 34 else if (guessNumber < randomNumber) 35 { 36 lowerLimit = guessNumber + 1; 37 Console.WriteLine("真遗憾,猜小了点,加油哦!\r\n"); 38 } 39 else if (guessNumber > randomNumber) 40 { 41 upperLimit = guessNumber - 1; 42 Console.WriteLine("真遗憾,猜大了点,加油哦!\r\n"); 43 } 44 } 45 46 if (guessTimes <= 5) 47 Console.WriteLine("真厉害!!!仅用了{0}次就猜中了!\r\n", guessTimes); 48 else if (guessTimes > 5 && guessTimes <= 10) 49 Console.WriteLine("用了{0}次才猜中,下次再接再厉!\r\n", guessTimes); 50 else if (guessTimes > 10) 51 Console.WriteLine("10次都没猜中,你输了!下次加油哦!\r\n"); 52 } 53 54 private static int InputNumber(int guessTimes, int lowerLimit, int upperLimit) 55 { 56 int guessNumber; 57 retry: try 58 { 59 Console.WriteLine("第{0}次猜,范围为 {1,-2} - {2,-2} ;", guessTimes, lowerLimit, upperLimit); 60 Console.Write("请输入你所猜的数字:"); 61 string guessNumberString = Console.ReadLine(); 62 if (string.IsNullOrEmpty(guessNumberString)) 63 throw new Exception("您未输入任何数,请重新输入!"); 64 else if (guessNumberString.Length > 4) 65 throw new Exception("您的输入超出界限,请重新输入!"); 66 else if (!(int.TryParse(guessNumberString, out guessNumber))) 67 throw new Exception("您输入的数字有问题,请重新输入!"); 68 else if (guessNumber < lowerLimit || guessNumber > upperLimit) 69 throw new Exception("您输入的数字超出界限,请重新输入!"); 70 } 71 catch (Exception e) 72 { 73 Console.WriteLine(e.Message + "\r\n"); 74 goto retry; 75 } 76 return guessNumber; 77 } 78 79 private static void PlayAgain() 80 { 81 Console.Write("是否再来一局? Y(是)/N(否):"); 82 string jugment = Console.ReadLine(); 83 string[] judgment1 = new string[] { "是", "Y", "y", "YES", "Yes", "yes" }; 84 string[] judgment2 = new string[] { "否", "N", "n", "NO", "No", "no" }; 85 while (!(judgment1.Contains(jugment) || judgment2.Contains(jugment))) 86 { 87 Console.Write("是否再来一局? Y(是)/N(否):"); 88 jugment = Console.ReadLine(); 89 } 90 if (judgment1.Contains(jugment)) 91 { 92 Console.Write("是否想清除之前的记录? Y(是)/N(否):"); 93 jugment = Console.ReadLine(); 94 while (!(judgment1.Contains(jugment) || judgment2.Contains(jugment))) 95 { 96 Console.Write("是否想清除之前的记录? Y(是)/N(否):"); 97 jugment = Console.ReadLine(); 98 } 99 if (judgment1.Contains(jugment)) 100 Console.Clear(); 101 else 102 Console.WriteLine("==================================================" + 103 "\r\n=================================================="); 104 105 Main(null); 106 } 107 } 108 } 109 }
说明:
1. \r\n 是换行符;
2. for 循环执行break后,i++ 不会执行;
3. 当 if 后的执行语句只有一条,可以省略“{ }”;
4. WriteLine 中的索引号 {0, -2} 就是普通的索引号 {0} ,-2 表示索引的内容至少占位 2 个字符,“-” 号表示左对齐,无符号则是右对齐。
个人不太喜欢写注释【不是不写(lll¬ω¬)】,觉得代码自己写的清晰就好。
欢迎留言!??
