Calling a variable with -Filter in Powershell

Question

This works:
Get-CsOnlineUser -Filter {LineURI -eq "tel:+12221234567"} | select UserPrincipalName,LineURI

via import-csv or a foreach loop, I would like to call a variable so that I can check a large group of numbers. This however doesn't work:
import-csv .\NumberCheck.csv | %{Get-CsOnlineUser -Filter {LineURI -eq ($_.LineURI)} | select UserPrincipalName,LineURI}

How do I call a variable when using -Filter?

Answer 1

Either use a script block or use the quotes syntax:

Import-CSV .\NumberCheck.csv | % { Get-CsOnlineUser -Filter "LineUri -eq '$($_.LineUri)'" } | select UserPrincipalName,LineURI  
  
Import-CSV .\NumberCheck.csv | % { Get-CsOnlineUser -Filter ([scriptblock]::Create("LineUri -eq '$($_.LineUri)'")) } | select UserPrincipalName,LineURI
