title: Import-CSV Where-Object as an Array
body: <p>I have the following code working - based on the great help here on stackoverflow - to parse a CSV file.  I would like to replace the $_.File - matches with data from a second CSV file that contains a list of files.  </p>
  
  <pre><code>Import-csv "D:\NTFSInfo_C_.csv" -header("File","ParentName","Extension","Attributes","SizeInBytes","CreationDate","LastModificationDate","LastAccessDate","LastAttrChangeDate","Status","USN","FRN","ParentFRN","FileNameCreationDate","FileNameLastModificationDate","FileNameLastAccessDate","FileNameLastAttrModificationDate")|
    Where-Object{($_.File -match "null.sys") -or ($_.File -match "explorer.exe")} |
    Select-Object File, CreationDate, FileNameCreationDate, ParentName |
    Export-CSV -Path c:\NTFS_KNOW_IOC.csv -NoTypeInformation
  </code></pre>
  
  <p>Question.  How do I read a list of file names from a TXT or CSV into an array and then use that array in the Where-Object as shown above?</p>
  
  <p>Thank you!</p>
