VB编程年会抽奖代码？

语言实现此程序。

以下是VB编程语言的实现示例：

'定义变量，存储每个奖项的人数

Dim firstPrize As Integer = 3

Dim secondPrize As Integer = 5

Dim thirdPrize As Integer = 12

Dim souvenirPrize As Integer = 10

'定义变量，存储抽奖结果

Dim firstPrizeList As New List(Of Integer)

Dim secondPrizeList As New List(Of Integer)

Dim thirdPrizeList As New List(Of Integer)

Dim souvenirPrizeList As New List(Of Integer)

'定义变量，存储编号滚动的起始编号

Dim currentNum As Integer = 1

'循环抽取各种奖项

For i As Integer = 1 To firstPrize

'抽取一等奖，并将编号添加到一等奖名单中

firstPrizeList.Add(currentNum)

currentNum += 1

Next

For i As Integer = 1 To secondPrize

'抽取二等奖，并将编号添加到二等奖名单中

secondPrizeList.Add(currentNum)

currentNum += 1

Next

For i As Integer = 1 To thirdPrize

'抽取三等奖，并将编号添加到三等奖名单中

thirdPrizeList.Add(currentNum)

currentNum += 1

Next

For i As Integer = 1 To souvenirPrize

'抽取纪念奖，并将编号添加到纪念奖名单中

souvenirPrizeList.Add(currentNum)

currentNum += 1

Next

'输出抽奖结果

Console.WriteLine("一等奖名单：" &String.Join(",", firstPrizeList))

Console.WriteLine("二等奖名单：" &String.Join(",", secondPrizeList))

Console.WriteLine("三等奖名单：" &String.Join(",", thirdPrizeList))

Console.WriteLine("纪念奖名单：" &String.Join(",", souvenirPrizeList))

Dim a(1 To 100) As String

Dim i As Integer, x As Integer

Const n = 3 'n的值可根据实际需要赋予不同的变量

Private Sub Command1_Click()

Timer1.Enabled = True

End Sub

Private Sub Command2_Click()

Timer1.Enabled = False

End Sub

Private Sub Form_Load()

Randomize '初始化随机数生成器

a(1) = "富士康" '以此将n个人的姓名保存在数组a中

a(2) = "庞麦郎"

a(3) = "非主流"

For i = 1 To n

List1.AddItem a(i)

Next

Timer1.Enabled = False

End Sub

Private Sub Timer1_Timer()

x = Rnd() * n + 1 '产生一个[1，n]中的随机整数并存入变量x中

Label2.Caption = a(x) '在标签Label2中显示下标变量a(x)的值（第x个人的姓名）

End Sub

在定义函数时有时在语句前，有的在语句后。
