foreach powershell i'm totally blind - powershell

Question

I have issues with this PowerShell script, if i execute the line without the foreach works great but with him don't show up nothing, can someone tell me why?
The foreach works fantastic by himselft he read all the data from the CSV but for some reason don't work, the CSV contain PC names like PC1, Pc-RRHH, JosePc from my network, like i say without the foreach is fine.
$computers = Import-Csv “C:\PowerShell\Pc.csv”
$array = #()
foreach($pc in $computers)
{
Get-WmiObject -Namespace ROOT\CIMV2 -Class Win32_Product -Computer $pc.computername
Select-Object Name, Version, PSComputerName
Where-Object -FilterScript {$_.Name -like “Adobe*”}
}
Best regards

Assuming your CSV file indeed has a header with column 'computername' in it, you can change your code to:
$computers = Import-Csv "C:\PowerShell\Pc.csv"
# let PowerShell collect the data for you in an array
$array = foreach($pc in $computers) {
# because NameSpace 'root/CIMV2' is the default, you do not have to specify that
Get-CimInstance -ClassName Win32_Product -ComputerName $pc.computername |
# or use the old Get-WmiObject
# Get-WmiObject -Class Win32_Product -Computer $pc.computername |
Where-Object { $_.Name -like "Adobe*" } |
Select-Object Name, Version, PSComputerName
}
Instead of piping to a Where-Object {..} clause, you can also use the -Filter parameter.
Beware though that this filter requires WQL syntax, which is different from PowerShell syntax.
$computers = Import-Csv "C:\PowerShell\Pc.csv"
# let PowerShell collect the data for you in an array
$array = foreach($pc in $computers) {
# because NameSpace 'root/CIMV2' is the default, you do not have to specify that
Get-CimInstance -ClassName Win32_Product -ComputerName $pc.computername -Filter "Name like 'Adobe%'" |
Select-Object Name, Version, PSComputerName
}
Or use the -Query parameter:
$computers = Import-Csv "C:\PowerShell\Pc.csv"
# the query string to filter on. Also WQL syntax
$query = "Select * from Win32_Product where Name LIKE 'Adobe%'"
# let PowerShell collect the data for you in an array
$array = foreach($pc in $computers) {
Get-CimInstance Get-CimInstance -Query $query -ComputerName $pc.computername |
Select-Object Name, Version, PSComputerName
}
From your comment, I gather that your CSV file isn't a CSV at all, but just a text file with pc names each on a separate line and that there is not header 'computername'.
In that case, change $computers = Import-Csv "C:\PowerShell\Pc.csv" to $computers = Get-Content -Path "C:\PowerShell\Pc.csv" and in the loop use -ComputerName $pc instead if -ComputerName $pc.computername
