Excel VBA : Regular Expression - get file name

Question

我如何获得文件名(没有路径和扩展名)

像“我的文件名”

从以下完整路径？

C:\A_B\C.D\E_\F0123456789\G\MyFileName.txt

Answer 1

Public Function GetFileNameWithoutExt(ByVal fullPath As String) As String
Dim fileName As String
Dim fileNameWithoutExt As String

Dim lastSlash As Integer
Dim positionOfDot As Integer

lastSlash = InStrRev(fullPath, "\")
fileName = Mid(fullPath, lastSlash + 1)

positionOfDot = InStr(1, fileName, ".")
fileNameWithoutExt = Mid(fileName, 1, positionOfDot - 1)

GetFileNameWithoutExt = fileNameWithoutExt
End Function

使用即时窗口

?GetFileNameWithoutExt("C:\A_B\C.D\E_\F0123456789\G\MyFileName.txt")

编辑 :另一种方法

Public Function GetFileNameWithoutExt2(ByVal fullPath As String) As String
Dim fileName As String
Dim splittedData
Dim fileNameWithoutExt As String

splittedData = Split(fullPath, "\")
fileName = splittedData(UBound(splittedData))

fileNameWithoutExt = Split(fileName, ".")(0)

GetFileNameWithoutExt2 = fileNameWithoutExt
End Function
