Question Besoin d'aide logique

Salut,
une solution en utilsant des objets et le cmdlet Compare-object :
[code:1]
$FullName=\"c:\temp\NomVM.txt\"

@\"
NomVM,1,2,3,4,5,6,7,8,9,10
VM1,OK,OK,OK,OK,OK,OK,OK,OK,OK,OK
VM2,OK,OK,OK,OK,OK,OK,OK,OK,OK,OK
VM3,OK,OK,OK,OK,OK,OK,OK,OK,OK,OK
VM4,OK,OK,OK,OK,OK,OK,OK,OK,OK,OK
VM5,OK,OK,OK,OK,OK,OK,OK,OK,OK,OK
\"@ > $FullName

$MyVms = Import-csv -Path $FullName

function New-VMInfo {
param ($Name)
New-Object PSObject -Property @{NomVM=$Name}
}

$Recherche=@(
New-VMInfo \"VM2\"
New-VMInfo \"VM5\"
New-VMInfo \"VM6\"
)

$Max=[Math]::Max($MyVMs.count,$Recherche.count)

Compare-Object $Recherche $MyVms -sync $Max -IncludeEqual -Property NomVM
# NomVM SideIndicator
#

---

---

# VM2 ==
# VM5 ==
# VM1 =>
# VM3 =>
# VM4 =>
# VM6 <=

Tu peux aussi rechercher l'occurence Compare-Object sur le forum, il y a qq posts plus explicite.

Avec ton code de départ :
[code:1]
foreach ($VM in $Recherche)
{
Write-Host \"recherche : ($vm.NomVM)\"
for ($i = 0; $i -lt $myvms.count; $i++)
{
Write-Host \"current : $($myvms[$i].NomVM)\"
if ($myvms[$i].NomVM -eq $VM.NomVM)
{
write-Warning \"Action $VM !\"
}
}
}
