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
vb.net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!
