注意:参数为动态数组;
Private Function MyF(ByRef d() As Integer)
ReDim d(4, 13) As Integer
Dim i As Integer
Dim j As Integer
Dim n As Integer
Dim MyNum(4) As Integer
For i = 1 To 4
MyNum(i) = 0
Next i
Randomize
For i = 1 To 4
For j = 1 To 13
n = Int(Rnd * 4 + 1)
Do While MyNum(n) = 13
n = Int(Rnd * 4 + 1)
Loop
d(i, j) = n
MyNum(n) = MyNum(n) + 1
Next j
Next i

首先在窗体上添加Button1,ListBox1,下面是完整代码
Public Class Form1
Public Sub BubbleSort(ByVal arr() As Integer) '冒泡法排序
Dim temp As Double
Dim i, j As Integer
For i = 0 To arr.GetUpperBound(0) - 1
For j = i + 1 To arr.GetUpperBound(0) - 1
If arr(i) arr(j) Then
temp = arr(j)
arr(j) = arr(i)
arr(i) = temp
End If
Next
Next
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click '调用
Dim arr() As Integer = {55, 22, 33, 11, 77, 88}
BubbleSort(arr) '调用排序过程
Me.ListBox1.Items.Clear()
For i = 0 To arr.GetUpperBound(0) - 1 '显示排序后结果
Me.ListBox1.Items.Add(arr(i).ToString)
Next
End Sub
End Class
