Question

I’m new to PowerShell. I would like to add a file path to an ArrayList every time it changes. However, this PowerShell script fails somehow. Any hints what might I be doing wrong?

$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "C:\Mydir"
$watcher.IncludeSubdirectories = $true
$watcher.EnableRaisingEvents = $true

$jobs = New-Object System.Collections.ArrayList

$changed = Register-ObjectEvent $watcher "Changed" -Action {
    $changedFile = $($eventArgs.FullPath)
    $jobs.Add($changedFile)
}

Answer 1

It’s a scope issue. Add the global scope modifier:

$global:jobs.Add($changedFile)

see about_Scopes for more help.
