method to use for array value when unknown size?

[kor]

I have a need to split apart a file path and look at the very last element. But I never know how big the array is going to be.

For instance, if I have a file path that looks like this

serversharefolderAfolderBfolderC

I need to look at the very last folder after the final "" (in this case, folderC)

But I could also have a file path that looks like

servershareFolderA

So regardless of how deep the file path goes, I always need to look at the last folder. I already know how to break apart the path, but not sure what method I would use to analyze the last folder when I don't know how deep the path could be.

Can anyone point me in the right direction?

If you're using StringSplit, the resultant array's [0] index will show you how many total elements there are.

Quick and dirty example:

$sDir = "c:\Users\Hades\Desktop\Test\Test1\Test2"
Local $aArray = StringSplit($sDir, "\")
$x = $aArray[0]

ConsoleWrite($aArray[$x] & @CRLF)

kor,

Use StringSplit with the count element and then use that count to index the final element:

#include <MsgBoxConstants.au3>

$sPath = "\\server\share\folderA\folderB\folderC"
$aSplit = StringSplit($sPath, "\")
MsgBox($MB_SYSTEMMODAL, "Final Folder", $aSplit[$aSplit[0]])

$sPath = "\\server\share\FolderA"
$aSplit = StringSplit($sPath, "\")
MsgBox($MB_SYSTEMMODAL, "Final Folder", $aSplit[$aSplit[0]]

Or use a RegEx:

#include <MsgBoxConstants.au3>

$sPath = "\\server\share\folderA\folderB\folderC"
$sFinalFolder = StringRegExpReplace($sPath, "^.*\\(.*)$", "$1")
MsgBox($MB_SYSTEMMODAL, "Final Folder", $sFinalFolder)

$sPath = "\\server\share\FolderA"
$sFinalFolder = StringRegExpReplace($sPath, "^.*\\(.*)$", "$1")
MsgBox($MB_SYSTEMMODAL, "Final Folder", $sFinalFolder)

ConsoleWrite($aArray[$x] & @CRLF)

Just curious, why do I have to turn $aArray[0] into a new variable $x ?

I've noticed that if I do ConsoleWrite($aArray[0]) I get a number, but when I do $aArray[$x] I get the value.

Why is that?

Edit: $aArray[$aArray[0]] also works, but just wondering why I need to nest the value.

I've done it for readability, especially if I am going to use that var elsewhere, but it is personal preference. You can use the method Melba suggests just as well.
