如何使用 Randomize 函数来随机化计时器间隔？

Question

我无法找出 vb.net 的代码来随机化某个计时器的间隔。对于每个 a = a + 1，都会有不同的间隔，对于每个 a = 1、a = 2、a = 3 等，标签上会显示不同的文本。

如果您知道如何实现这一点，请提供帮助。 谢谢。

Answer 1

我可能不太明白这样的事情

调暗 arrLbls(3) 作为标签
'具有 4 个标签类型元素的数组'
'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

`

Answer 2

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
