如何在数组中存储随机唯一编号 [英] How to store random unique no in array

问题描述

当我单击按钮时，我有三个文本框和一个按钮，然后在文本框中显示随机否.
如果文本框为5，则随机数为1到5.

I have three text box and one button when i click on the button then display random no in the textbox.
if text box is 5 then random is within 1 to 5.

推荐答案

private Random rand = new Random();
...
int max = int.Parse(myTextBox.Text);
int val = rand.Next(1, max+1);
myOtherTextBox.Text = val.ToString();

您可以使用Random类，这是一个示例:

Hi,
You can use Random class, here is a sample:

Random rand = new Random();
int rand1_5 = rand.Next(int.Parse(txt1.Text), int.Parse(txt2.Text));

为了保存随机数，可以将它们放入ArrayList

In order to save random numbers, you can put them in an ArrayList

ArrayList arr = new ArrayList();
arr.Add(rand1_5);
