Powershell Script reading file into array - powershell

Question

I have a script I'm working on. I want it to read in a column named ComputerName and one named UserName.
My CSV file looks like this:
ComputerName | Username
computer01 | user1
computer02 | user2
The Pipes are representing cells in excel.
Here's my script:
$computerName = #()
$userName = #()
Import-Csv C:\test\script\Computername_username_test.csv -Delimiter "|" |`
ForEach-Object
{
$computerName += $_.ComputerName
$userName += $_.UserName
}
$destination = New-Item -ItemType Directory -Path C:\test\$userName\dictionary_Files\ -force
$fileList = Get-WmiObject -Class CIM_DataFile -Filter "Drive='C:' And Extension='dic'" -Computername $computerName
foreach ($file in $fileList)
{
$drive, $path = $file.Name.Split('\',2)
$drive = $drive -replace ':','$'
$remoteFile = "\\$computerName\$drive\$path"
Write-Verbose "Copy $remoteFile to $destination"
Copy-Item $remoteFile -Destination $destination -Confirm
}
My goal is to search the C drive of the remote computer for all files with the .dic extension and copy them to a location inside a folder that is named the same as their username from the excel sheet.
When I run this I'm getting the following:
PS C:\Test\Script> C:\Test\Script\DicFiles03_importCSV.ps1
cmdlet ForEach-Object at command pipeline position 2
Supply values for the following parameters:
Process[0]:
$computerName += $_.ComputerName
$userName += $_.UserName
Get-WmiObject : Cannot validate argument on parameter 'ComputerName'. The argument is null, empty, or an element of the argument
collection contains a null value. Supply a collection that does not contain any null values and then try the command again.
At C:\Test\Script\DicFiles03_importCSV.ps1:13 char:102
+ ... -Filter "Drive='C:' And Extension='dic'" -Computername $computerName
+ ~~~~~~~~~~~~~
+ CategoryInfo : InvalidData: (:) [Get-WmiObject], ParameterBindingValidationException
+ FullyQualifiedErrorId : ParameterArgumentValidationError,Microsoft.PowerShell.Commands.GetWmiObjectCommand
Thank you for your help.

I'm think its because you have your { after the foreach-object on the next line powershell is a scripting language so its particular about line endings.
