Question

在下面的示例语法中，如何将每个元素添加到新数组而不是打印？我不确定怎么做，因为我不知道数组的大小，因为它可能是0（不需要初始化数组）或者它可能是它迭代的数组的Ubound。 / p>

Option Compare Database
Option Explicit

Function TestIt()
Dim animalarray As Variant, xyz As Variant
animalarray = Array("Cat", "Cow", "Camel", "Dire Wolf", "Dog", "Coyote", "Rabbit", "Road runner", "Cougar")

For Each xyz In animalarray
  If Left(CStr(xyz), 1) = "C" Then
    Debug.Print CStr(xyz)
  End If
Next

End Function

Answer 1

您可以使用Redim Preserve：

Sub TestIt()
    Dim animalArray(): animalArray = Array("Cat", "Cow", "Camel", "Dire Wolf", "Dog", "Coyote", "Rabbit", "Road runner", "Cougar")
    Dim anotherArray(): anotherArray = Array("Lion", "Tiger", "Leopard")

    Dim xyz As Variant
    For Each xyz In animalArray
      If Left(CStr(xyz), 1) = "C" Then
        ReDim Preserve anotherArray(UBound(anotherArray) + 1)
        anotherArray(UBound(anotherArray)) = xyz
      End If
    Next

    For Each xyz In anotherArray
        Debug.Print xyz
    Next
End Sub

Answer 2

它更简单：

Function TestIt()

    Dim animalarray As Variant
    Dim newarray As Variant
    Dim xyz As Variant

    animalarray = Array("Cat", "Cow", "Camel", "Dire Wolf", "Dog", "Coyote", "Rabbit", "Road runner", "Cougar")
    newarray = animalarray

    For Each xyz In newarray
        If Left(CStr(xyz), 1) = "C" Then
            Debug.Print CStr(xyz)
        End If
    Next

End Function
