VB.NET 如何带参数构造函数对象或是类

public structure struc

public name as string

public shengao as integer

......

end structure

public items as struc()

readonly property people(argname as string) as struc

get

for each i as struc in items

if i.name=argname then reture i

next

end get

end property

people也可以是类的构造方法,而shengao等是类的成员,但你的写法是错误的,构造方法必须用new实例化

VB.NET自定义函数

Public Function Zuhe(ByVal qa As String) As String

Select Case qa

Case "0"

Return "1"

Case "1"

Return "0"

Case else

Return "XXXX"

End Select

End Function

vb.net 编写一个函数

注意：参数为动态数组；

Private Function MyF(ByRef d() As Integer)

Dim i As Integer

Dim j As Integer

Dim n As Integer

MyNum(i) = 0

Next i

Randomize

Loop

d(i, j) = n

MyNum(n) = MyNum(n) + 1

Next j

vb.net中创建类

不熟悉VB,如有不妥的地方请包涵!

Public Class Stack

Dim aryData() As Integer

Sub New(ByVal Num As Integer)

Dim aryData(Num) As Integer

End Sub

Function Pop() As Integer

If (aryData.Length = 0) Then

Return 0

Else

Dim a As Integer

a = aryData(aryData.Length)

Return a

End If

Sub Push(ByVal n As Integer)

For Each i As Integer In aryData

aryData(i) = n

End

Continue For

Next

Sub PrintStack()

Print(aryData(i))

End Class

VB.net 如何编写一个可以返回数组的函数（过程）?

public function createstringarr() as string()

end function

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

End?Sub

Private?Sub?Button1_Click(ByVal?sender?As?System.Object,?ByVal?e?As?System.EventArgs)?Handles?Button1.Click?'调用

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)

End?Class
