如何在visual basic 6中检索字符串数组的最后一个元素？

我正在处理具有多个点的文件名，这些点被拆分为一个数组，我只想操纵扩展名。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

Answer 1

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

Answer 2

realExt = aPath(ubound(aPath))

Answer 3

但是，如果它真的只是您之后的延伸，那么这就可以胜任：

Private Sub Form_Load()
    Dim sFileName As String
    Dim lPos As Long
    Dim sRealExt As String

    sFileName = "A long dotty.file.name.txt"
    lPos = InStrRev(sFileName, ".")
    If lPos Then sRealExt = Mid$(sFileName, lPos + 1)
End Sub
