方法名称：next(i)；功能描述：返回一个0~i之间的整数
方法名称：next(i，j)；功能描述：返回一个i~j之间的整数
方法名称：Nextdouble()；功能描述：返回一个0~1之间的随机小数
================
使用方法：
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim rand = New System.Random()
MsgBox(rand.next().ToString())
End Sub
==========================
产生N个不同数的话，我给你个我写的VB的代码，你稍微改下：
产生0-10的数：
Private Sub Command1_Click()
Randomize
Dim a(10) As Long
n = 10
For i = 0 To n
a(i) = Int(Rnd() * (n + 1))
For j = 0 To i - 1
If a(i) = a(j) Then
i = i - 1
Exit For
End If
Next
Next
For i = 0 To n
Print a(i)
Next
End Sub
编写一个 VB.NET 程序,产生 100 个 100 以内的随机数，将他们从大到小排序后输出
Private Sub Command1_Click()
Dim a(1 To 100) As Integer
Dim i As Integer, j As Integer, k As Integer
For i = 1 To 100 '给数组a一百个元素赋值，并换每行十个数字输出来窗体上
a(i) = Int(Rnd * 101)
k = k + 1
Print Tab((k - 1) * 5); a(i);
If k = 10 Then k = 0: Print
Next i
For i = 100 To 2 Step -1 '用冒泡排序法对数组进行排序
For j = 1 To i - 1
If a(j) a(j + 1) Then
t = a(j): a(j) = a(j + 1): a(j + 1) = t
End If
Next j
Next i
For i = 1 To 100 '输出排好序的数组
k = k + 1
Print Tab((k - 1) * 5); a(i);
If k = 10 Then k = 0: Print
Next i
End Sub
vb点虐 中产生三位正整数的随机数的程序写法
'项目：VB中产生在一定正整数范围内的不重复的随机数'作者：qq15495835Private Sub Command1_Click() Max = 100 '随机数上限值 Min = 1 '随机数下限值 Amount = 10 '产生号码数量(数量值应小于随机数上限值-随机数下限值)否则会产生死循环 ReDim a(Amount) Randomize For i = 0 To Amount a(i) = Int((Max - Min + 1) * Rnd + Min) For j = 0 To i If i j And a(i) = a(j) Then i = i - 1 Next Next Text1 = Join(a, vbCrLf)End Sub'请采纳参考！谢谢！
怎么用vb点虐 随机产生5个不同的数，范围1-33，求帮忙改一下
Private Sub Command1_Click()
Dim num(6) As Integer
Dim i As Integer, j As Integer
Dim tmp As Integer
Randomize '防止每次生出随机数一样
For i = 0 To 5
num(i) = Int(Rnd * 53) + 1
Next
PrintNum "新生成的6个随机数为：", num()
For i = 0 To 5
For j = 0 To 5
If num(j) num(j + 1) Then
tmp = num(j)
num(j) = num(j + 1)
num(j + 1) = tmp
End If
Next
Next
PrintNum "排序后的6个随机数为：", num()
End Sub
