WindowsPhone 产生规定范围内的不重复随机数 by VB

 1 Module RandNumber
 2     Public Nums() As Integer
 3     Public Sub StartCreateNumber(TopNumber As Integer)
 4         Dim i, j, k As Integer
 5         Dim temp(TopNumber) As Integer
 6         ReDim Nums(TopNumber)
 7         Dim rnd As New Random(Seed:=Date.Now.Second)
 8         For i = 1 To TopNumber
 9             Nums(i) = 0
10         Next
11         For j = 1 To TopNumber
12             k = rnd.Next(1, TopNumber + 1)
13             While Nums(k) <> 0
14                 k = rnd.Next(1, TopNumber + 1)
15             End While
16             Nums(k) = j
17         Next
18     End Sub
19 End Module

本例子是从 1至 n(代码里编号名为TopNumber)生成随机的不重复的数字。

主要思想是 随机生成数据下标,对生成的下标 进行顺序从1至n 赋值。

代码是用模块写的,可以随意调用。
