Question

I wish to return from the following powershell function if I find a match (for a more complete code sample see my codereview question):

Function Find-Property($fileName, $PropertyName)
{
    $shellfolder = Create-ShellFolder $fileName
    0..287 | Foreach-Object {
        if($PropertyName -eq $shellfolder.GetDetailsOf($null, $_)){ return $_ }
    }
}

This code just appears to return from the scope of the if conditional, which is not so useful.

How can I do this? Do I need a labeled break somewhere?

If you wish to use the return statement to exit the function you can use the foreach keyword instead of the ForEach-Object cmdlet. Here’s a demo:

function Foo {
    foreach ($number in (0..287)) {
        $number # Just show our current iteration.
        if ($number -eq 50) {
            return $number
        }
    }
}
