vb.net生成随机数组 vb随机生成n个数

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 = k1
Print Tab((k - 1) * 5); a(i);
If k = 10 Then k = 0: Print
Next i
Print
Print
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(j1) Then
t = a(j): a(j) = a(j1): a(j1) = t
End If
Next j
Next i
For i = 1 To 100'输出排好序的数组
k = k1
Print Tab((k - 1) * 5); a(i);
If k = 10 Then k = 0: Print
Next i
End Sub
vb.net怎样生成随机数Dim a As Integer = CInt(Int((9999 - 10001) * Rnd()1000))
注:randomvalue = https://www.04ip.com/post/CInt(Int((upperbound - lowerbound1) * Rnd()lowerbound))
这里,upperbound 是此范围内最大的数 , lowerbound 是此范围内最小的数 。
vb.net产生随机数方法名称:next();功能描述:返回一个0~2147483647之间的整数
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() * (n1))
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
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vb.net生成随机数组的6个随机数为vb.net生成随机数组:", num()
For i = 0 To 5
For j = 0 To 5
If num(j)num(j1) Then
tmp = num(j)
num(j) = num(j1)
num(j1) = tmp
End If
Next
Next
PrintNum "排序后的6个随机数为vb.net生成随机数组:", 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vb.net生成随机数组的不重复vb.net生成随机数组的随机数'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 Amounta(i) = Int((Max - Min1) * RndMin)For j = 0 To iIf ij And a(i) = a(j) Then i = i - 1Next Next Text1 = Join(a, vbCrLf)End Sub'请采纳参考vb.net生成随机数组!谢谢!
