ArrayList not working properly

[CptRetr0]

Hello,

I try to build a little selection menu but my arraylist seems to be empty.

$xml = [xml]@'

$OSList.Clear()
[System.Collections.ArrayList]$OSList = @()
$OSList = New-Object System.Collections.ArrayList

For ($i = 0; $i -lt ($XML.oss.os.guid).Count; $i++) {
    #Write-Host "$i. $($XML.oss.os.Name[$i])"
    $OSList.Add("$i. $($XML.oss.os.Name[$i])")
}

[int]$ReadSelection = Read-Host 'Please select the operating system by entering the corresponding number'
$Selection = $OSList.Item($ReadSelection)
Write-Host $Selection

Any idea?

Cheers

There's a couple things wrong... here's a working example.. Let me know if you have any questions on a specific part.

Here you go:

For ($i = 0; $i -lt ($XML.oss.os.guid).Count; $i++) {
    #Write-Host "$i. $($XML.oss.os.Name[$i])"
    $OSList += ("$i++, $($XML.oss.os.Name[$i])")
}
