Question

我无法弄清楚vb.net的代码会随机化某个计时器的间隔。对于每个a = a + 1，将存在不同的间隔，并且对于每个a = 1，a = 2，a = 3等，将在标签上显示不同的文本。

如果您知道如何使其成为可能，请提供帮助。谢谢。

Answer 1

我可能不太明白这样的事情

Dim arrLbls（3）作为标签
'带有4个类型标签元素的数组' '填充数组'

arrLbls(0) = Label1
arrLbls(1) = Label2
arrLbls(2) = Label3
arrLbls(3) = Label4

'loops trought array'

For i As Int16 = 0 To arrLbls.Length - 1
    arrLbls(i).Text = "Label from the array " & i + 1
Next

`

使用Random类

   Public Function RandomNumber(ByVal MaxNumber As Integer, _
    Optional ByVal MinNumber As Integer = 0) As Integer

      'initialize random number generator
        Dim r As New Random(System.DateTime.Now.Millisecond)

      'if passed incorrect arguments, swap them
        'can also throw exception or return 0

        If MinNumber > MaxNumber Then
            Dim t As Integer = MinNumber
            MinNumber = MaxNumber
            MaxNumber = t
        End If

        Return r.Next(MinNumber, MaxNumber)

    End Function

如何使Randomize函数随机化定时器间隔？
