Export-Csv-Hilfe in PowerShell

Question

Unten ist der letzte Teil eines Skripts, das ich für eine Remote-Inventarisierung von Hosts in meinem Netzwerk übernommen habe. Ich habe am Ende des Skripts mit dem Export-Csv zu kämpfen. Die einzige Möglichkeit, CSV-Dateien zu erhalten, besteht darin, das "-Append" für "-Force" zu ersetzen. Wie erwartet, wird nur der letzte Host in der angegebenen Datei in die foreach-Schleife geschrieben (weil die Schleife jeden Eintrag ohne überschreibt) das "-Append", so dass mir nur die Informationen des letzten Hosts in der exportierten CSV-Datei verbleiben). Mit dem -Append wird die CSV-Datei nicht einmal erstellt; Ich habe auch versucht, die CSV-Datei vor dem Ausführen des Skripts zu erstellen, jedoch wird nichts in die Datei geschrieben. Was mache ich falsch?

foreach ($Network in $Networks) { 
$IPAddress = $Network.IpAddress[0] 
$MACAddress = $Network.MACAddress 
$systemBios = $Bios.serialnumber 
$OutputObj = New-Object -Type PSObject 
$OutputObj | Add-Member -MemberType NoteProperty -Name ComputerName -Value $Computer.ToUpper() 
$OutputObj | Add-Member -MemberType NoteProperty -Name Manufacturer -Value $Hardware.Manufacturer 
$OutputObj | Add-Member -MemberType NoteProperty -Name Model -Value $Hardware.Model 
$OutputObj | Add-Member -MemberType NoteProperty -Name CPU_Info -Value $cpu.Name 
$OutputObj | Add-Member -MemberType NoteProperty -Name SystemType -Value $Hardware.SystemType 
$OutputObj | Add-Member -MemberType NoteProperty -Name BuildVersion -Value $SysBuild.BuildVersion 
$OutputObj | Add-Member -MemberType NoteProperty -Name OS -Value $OS.Caption 
$OutputObj | Add-Member -MemberType NoteProperty -Name SPVersion -Value $OS.csdversion 
$OutputObj | Add-Member -MemberType NoteProperty -Name SerialNumber -Value $systemBios 
$OutputObj | Add-Member -MemberType NoteProperty -Name IPAddress -Value $IPAddress 
$OutputObj | Add-Member -MemberType NoteProperty -Name MACAddress -Value $MACAddress 
$OutputObj | Add-Member -MemberType NoteProperty -Name UserName -Value $username.Name 
$OutputObj | Add-Member -MemberType NoteProperty -Name Last-Login -Value $username.LastWriteTime 
$OutputObj | Add-Member -MemberType NoteProperty -Name C:_GBfreeSpace -Value $driveSpace.GBfreespace 
$OutputObj | Add-Member -MemberType NoteProperty -Name Total_Physical_Memory -Value $totalMemory 
$OutputObj | Add-Member -MemberType NoteProperty -Name Last_Reboot -Value $lastboot 
$OutputObj | Export-Csv -Append -Path "C:\Users\User1\Desktop\Scripts\pcInventory.csv" -NoTypeInformation 

Answer 1

(nicht getestet) eine Option wäre, den Export außerhalb der Schleife setzen wie diese

$results = foreach ($Network in $Networks) { 
    $IPAddress = $Network.IpAddress[0] 
    $MACAddress = $Network.MACAddress 
    $systemBios = $Bios.serialnumber 

    [pscustomobject]@{ 
     ComputerName = $Computer.ToUpper() 
     Manufacturer = $Hardware.Manufacturer 
     Model = $Hardware.Model 
     CPU_Info = $cpu.Name 
     SystemType = $Hardware.SystemType 
     BuildVersion = $SysBuild.BuildVersion 
     OS = $OS.Caption 
     SPVersion = $OS.csdversion 
     SerialNumber = $systemBios 
     IPAddress = $IPAddress 
     MACAddress = $MACAddress 
     UserName = $username.Name 
     Last_Login = $username.LastWriteTime 
     C_GBfreeSpace = $driveSpace.GBfreespace 
     Total_Physical_Memory = $totalMemory 
     Last_Reboot = $lastboot 
    } 
} 

$results | Export-Csv -Path 'C:\Users\User1\Desktop\Scripts\pcInventory.csv' -NoTypeInformation 

Answer 2

die Sie interessieren außerhalb der Schleife. Ich habe es nicht für Ihr Beispiel getestet.

$rows | ConvertTo-Csv | Add-Content 'C:\Users\User1\Desktop\Scripts\pcInventory.csv' 

Fügen Sie diese vor Beginn der Schleife:

$rows = @() 

Und fügen kurz vor dem Ende der Schleife:

$rows += $OutputObj 

Hier ist ein Beispiel ein Dummy-Objekt:

$Networks = @("Network1", "Network2") 
$rows = @() 

foreach ($Network in $Networks) { 

    $OutputObj = New-Object -Type PSObject 
    $OutputObj | Add-Member -MemberType NoteProperty -Name ComputerName -Value $Network 
    $OutputObj | Add-Member -MemberType NoteProperty -Name Manufacturer -Value $Network 
    $rows += $OutputObj 

} 

$outFile = 'C:\Users\User1\Desktop\Scripts\pcInventory.csv' 

# Need the following to avoid adding header row each time. 
if (test-path $outFile){ 
    $ExistingRowCount = (Import-Csv "$outFile" | measure-Object).Count 
    if ($ExistingRowCount -gt 0){ 
     $rowToStartAppending = 1 
    }else{ 
     $rowToStartAppending = 0 
    } 
}else{ 
    $rowToStartAppending = 0 
} 

$csvContent = $rows | ConvertTo-Csv -NoTypeInformation 
$csvContent[$rowToStartAppending..$csvContent.count] | Add-Content $outFile

Dies ist ein scr ipt ich habe andere Eigenschaften von dem, was Sie brauchen

$serverList = "c:\COMPUTERS.TXT" 
$outputCSV = "D:\RFV.csv"
