Private Sub Command1_Click()
If b 5 Then
b = b + 1
x = Int(n * Rnd()) + 1
Text1.Text = Text1.Text a(x) " "
a(x) = a(n)
n = n - 1
Else
Call Form_Load
End If
End Sub
Private Sub Form_Load()
Randomize
n = 13: b = 0
For i = 1 To 13
a(i) = i
Next i
Text1.Text = ""

vb.net怎么随机生成5个不同是数(1-33内的数),大神求救
想要生成多少个都行。
Randomize()随机打乱
dim a1 as integer=cint(rnd()*32))+1
dim a2 as integer=cint(rnd()*32))+1
dim a3 as integer=cint(rnd()*32))+1
dim a4 as integer=cint(rnd()*32))+1
dim a5 as integer=cint(rnd()*32))+1
怎么用vb.net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
