How to handle an expression when input is taken from a csv

Question

Beginner with powershell and looking for some help with the @{Label='ID'; expression={??} section please:-

$ID = @()
Import-Csv C:\computers2.csv | ForEach-Object {$ID += $_.ID}
Get-WmiObject -Class Win32_LogicalDisk -ComputerName $ID | 
Select-Object -Property DeviceID, @{Label='ID'; expression= 
{$ID}},
@{Label='Total (Gb)'; expression={($_.Size/1GB).ToString('F2')}},
@{Label='Free (Gb)'; expression= 
{($_.FreeSpace/1GB).ToString('F2')}},
@{label='Percent'; expression={[Math]::Round(($_.freespace / 
$_.size) * 100, 2)}} | Format-Table
