使用vb.net编写一个函数,函数只有一个参数
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
vB.net语言编写N个数字数组排序可自定义数组长度的
Dim d() As Integer
Dim n As Integer
Dim i As Integer
Dim j As Integer
Dim T As Integer
n = Val(InputBox("请输入n,确定数组的元素个数"))
ReDim d(n)
'用随机函数生成正整数数组
Randomize
For i = 1 To n
d(i) = Int(Rnd * 100 + 1)
Next i
'输出
For i = 1 To n
Print d(i),
Next i
'从小到大排序
For i = 1 To n - 1
For j = i + 1 To n
If d(i) d(j) Then
T = d(i)
d(i) = d(j)
d(j) = T
End If
Next j
Next i
'输出
For i = 1 To n
Print d(i),
Next i
vb.net 编写一个函数
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
End Function
VB.net 如何编写一个可以返回数组的函数(过程)?
public function createstringarr() as string()
return new string(){"d1","d2","d3","d4"}
end function
vb.net 数组的定义方法
1、点击VS工具。
2、打开后,新建一个Windows窗体应用程序。
3、新建完毕后,如图所示。
4、拖动一个按钮。
5、定义数组最常见的方法,如图示。
6、运行后,点击按钮,弹出提示正常。
7、定义数组第二种方法,属于动态的方法。
8、运行后,点击按钮,数组成功输出。
vb.net 函数或者过程作为数组
thr_test(i) = New System.Threading.Thread(New System.Threading.ParameterizedThreadStart(Sub()
直接写过程代码
End Sub))
