VB设计一个随机抽奖程序，当单击开始按钮时，在两个文本框产生【1，20】之间的随机整数？

假定开始按钮是 Command1，两个文本框分别是 Text1、Text2

Private Sub Command1_Click()

Randomize

Text1.Text = Int(Rnd * 20) + 1

Text2.Text = Int(Rnd * 20) + 1

End Sub

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))
