New to powershell and my foreach keeps failing. Trying to iterate over a list of cert files but it fails. Probably simple

Question

Problem:

When I import a cert individually, outside of a foreach, it prints the thumbprint as needed; however, I need to iterate through a list of .cer files on a fileshare so that I can run them against a local machine's currently installed certs. The moment I try to run the list of certs through my foreach, it fails.

Working code (individually)

<# Notice the explicite .cer file #>
$certGet = Get-ChildItem -Path \\fileserver\...\Certs\cert.cer

$cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2
$cert.Import($certGet)
$cert.Thumbprint

I am trying to scale this working code out into a foreach to iterate over a list or .cer files. Below is my attempt thus far.

Failing code:

$certGetList = Get-ChildItem -Path \\fileserver\...\Certs

$certGetList | ForEach-Object {
    $cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2
    $cert.Import($_)
    $cert.Thumbprint
}

Error message

ERROR: Exception calling "Import" with "1" argument(s): "The system cannot find the file specified.

Answer 1

Of course... so simple.

Answer:

$cert.Import($certGetList + "\" + $_)

Somehow, it loses the origin of the object and tries to find the relative file locally, instead of on the network share. I needed to explicitly direct it to the network share for each iteration.
