vb.net 随机出数字，但要求包含特定数字如何做？下面是你需要的，经过三次随机，可以看一下，直接调用函数返回一个字符就是你要的，看不懂再追问哈
Structure jiqi
Dim num As Integer
Dim num2 As Integer
End Structure
Public Function chansheng() As String
Dim str As String = ""
Dim n As Integer = 0
Dim p68 As Integer
Randomize()
p68 = Int(Rnd() * 2)1
Dim a(10), b(8) As Integer
For i = 1 To 6
b(i) = i - 1
Next
b(7) = 7
b(8) = 9
For i = 1 To 6
Randomize()
a(i) = b(Int(Rnd() * 8)1)
Next
If p68 = 1 Then
For i = 7 To 10
a(i) = 6
Next
ElseIf p68 = 2 Then
For i = 7 To 10
a(i) = 8
Next
End If
Dim c(10) As Integer
Dim temp As jiqi
Dim pi(10) As jiqi
【随机数字vb.net 随机数字抽取】For i = 1 To 10
pi(i).num = a(i)
pi(i).num2 = Int(Rnd() * 1000)10
Next
For i = 1 To 10
For j = 1 To 10 - i
If pi(j).num2pi(j1).num2 Then
temp = pi(j1)
pi(j1) = pi(j)
pi(j) = temp
End If
Next j
Next i
For i = 1 To 10
str = strpi(i).num
Next
Return str
End Function
VB.NET中怎么实现每单击一次按钮，文本框就多出现一个1-13的随机数字？Dim n As Integer, b As Integer, a(13) As Integer
Private Sub Command1_Click()
If b5 Then
b = b1
x = Int(n * Rnd())1
Text1.Text = Text1.Texta(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 = ""
End Sub
vb.net输出随机数字Label1.Text=a(i,j)" "
相当于
Label1.Text = Label1.Texta(i,j)" "
1 。不能 ， 语法问题 。
2 。“ ”中包含的是空格，这句话相当于将数组a中的所有数据罗列出来，空格是分隔符，没有它数据就连在一起了，你没法区分了！
