C#使用随机数生成元素不重复的数组

通过for与while的嵌套做了一个排除相同数字的审查机制，如果生成了数组中已有的数字就重新生成一个数字，继续循环排查，直到生成的数字是数组中不存在的数字

数组长度不能超过随机数范围否则会死循环

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

using System;   namespace notRepeat {     class Program     {         static void Main(string[] args)         {             int[] vs = new int[10];//数组长度不能超过随机数选取范围             Random random = new Random();             bool a;             for (int i = 0; i < vs.Length; i++)             {                 vs[i] = random.Next(1, 11);//此处代表随机数从[1,11)范围内取                 a = true;                 while (a)                 {                     int k = 0;                     for (int j = 0; j < i; j++)                     {                         if (vs[i] == vs[j])                         {                             k++;//如果生成的数在数组中不存在则k值不变                             vs[i] = random.Next(1, 11);                             break;//结束内层for循环                         }                     }                     if(k == 0)//k值为0代表生成的数在数组中不存在                     {                         a = false;//结束while循环                     }                 }             }             foreach (var temp in vs)//foreach输出数组内容             {                 Console.WriteLine(temp);             }         }     } }
