vb6 - 在vb6中获取字符串数组的最后一个元素？

Question

如何在 Visual Basic 6 中检索字符串数组的最后一个元素？

我正在处理带有多个点的文件名，这些点被分成一个数组，并且我只想操作扩展名。以下代码有效，但有一个我想删除的硬编码元素。

Private Sub Form_Load()
    Dim aPath() As String
    Dim FileName As String
    Dim realExt As String

    FileName = "A long dotty.file.name.txt"
    aPath = Split(FileName, ".")

    realExt = aPath(3) ' <-- how to not hardcode?'

    MsgBox ("The real extension is: " & realExt)
    Unload Me
End Sub

我认为使用 Ubound 应该可以解决问题:

Private Sub Form_Load()
    Dim aPath() As String
    Dim FileName As String
    Dim realExt As String

    FileName = "A long dotty.file.name.txt"
    aPath = Split(FileName, ".")

    realExt = aPath(UBound(aPath))

    MsgBox ("The real extension is: " & realExt)
    Unload Me
End Sub
