问题描述

大家好，

hi all,
for my program i want to choose from some numbers that are not sequentally. for example i want to choose from 2,3, 5, 8 randomly.what i must do. thank you all.

推荐答案

制作一个数组，用你想要随机化的数字填充



使randomNumberGenerator从零到↑array.Count然后只给出数组[randomGeneratedNumber]

make an array which you will fill with the numbers you want to randomize

make a randomNumberGenerator from zero to ↑array.Count and then just give out the array[randomGeneratedNumber]

int[] asdf = {2,3,5,8};

var r = new Random();
// print random integer >= 0 and  < 4
Console.WriteLine(r.Next(4));

// print random integer >= 0 and < 4
Console.WriteLine(r.Next(0, 4);)

Console.WriteLine(asdf[r.Next(0,3)]);

把你的号码放在一张桌子里。

在0和表格大小之间随机做出（强制转换为整数）。

然后选择表格的成员[随机]。

你也可以使用词典或其他语言功能。

祝你好运。

Hi,
Put your number in a table.
Do random between 0 and size of table ( cast to integer).
Then select the member of table like Table[random].
you can also use a dictionnary or other feature of langage.
Best regards.
