随机数问题

Question

先对你的5个元素赋值从0到4；
然后Random r = new Random();
   Response.Write(r.Next(4));

Answer 1

string[] str = {'1','2','3','4','5'};
Random rand = new Random();
textbox1.Text = str[rand.Next(0,4)];

Answer 2

 int[] args ={ 1,2,3,4,5};
           
            Random r=new Random();
           
            Response.Write(args[r.Next(4)]);这样就能显示出来。

Answer 3

 string[] temp = new string[] {  "0","1","2","3","4"};
            Random rd = new Random();
            string num;
            string sum="";
            for (int i = 0; i < 5;i++ )
            {
                num = temp[rd.Next(5)];
                sum = num + sum;
               
            }            Console.WriteLine(sum);

Answer 4

string[] s={"","","","",""};
Random rnd = new Random;
string str= rnd.Next(5).ToString();

Answer 5

string[] str = {'1','2','3','4','5'}; 
Random rand = new Random(); 
textbox1.Text = str[rand.Next(0,4)]; 就这样子吧

Answer 6

int[] args ={ 1,2,3,4,5,.,.,.,.,.,.,.,n}; 
          
            Random r=new Random(); 
          
            Response.Write(args[r.Next(n-1)]); 这样就能显示出来。
