conver powershell script to csv - powershell

Question

im doing some testing with powershell to list hardware information of each computer in my domain. my script will get a list of computer from a text file that i created using powershell.
$arrComputers = get-Content -Path "C:\powershell\List.txt"
foreach ($strComputer in $arrComputers)
{
$colItemsOs = get-wmiobject -class "Win32_OperatingSystem" -namespace "root\CIMV2" `
-computername $strComputer
foreach ($objItem in $colItemsOs)
{
Write-host "Computer Name: " $strComputer
Write-host "OsName: " $objItem.Name
Write-host "Version: " $objItem.Version
}
$colItemsCompsys = get-wmiobject -class "Win32_ComputerSystem" -namespace "root\CIMV2" `
-computername $strComputer
foreach ($objItem in $colItemsCompsys)
{
Write-host "Memory: " $objItem.TotalPhysicalMemory
Write-host "Manufacturer: " $objItem.Manufacturer
Write-host "Model: " $objItem.Model
Write-host "Domain: " $objItem.Domain
}
$colItemsSysEnc = get-wmiobject -class "Win32_SystemEnclosure" -namespace "root\CIMV2" `
-computername $strComputer
foreach ($objItem in $colItemsSysEnc)
{
Write-host "SerialNumber: " $objItem.SerialNumber
}
$colItemsProcessor = get-wmiobject -class "Win32_Processor" -namespace "root\CIMV2" `
-computername $strComputer
foreach ($objItem in $colItemsProcessor)
{
Write-host "Processor: " $objItem.Name
}
$colItemsIP = get-wmiobject -class "Win32_NetworkAdapterConfiguration " -namespace "root\CIMV2" `
-computername $strComputer -Filter "IpEnabled = TRUE"
foreach ($objItem in $colItemsIP)
{
Write-host "IPAddress: " $objItem.IpAddress
}
Write-host | Out-File c:\powershell\reportbeta.csv
}
however, i am unable to do so. how do i produce the result in csv file which will be able to be uploaded to my database using sqlcmd later on.
what am i missing out?
thank you
ive managed to display output in text file. however, only 1 record is displayed.
$arrComputers = get-Content -Path "C:\powershell\List.txt"
foreach ($strComputer in $arrComputers)
{
$colItemsOs = get-wmiobject -class "Win32_OperatingSystem" -namespace "root\CIMV2" `
-computername $strComputer
foreach ($objItem in $colItemsOs)
{
$strComputer
$Name =$objItem.Name
$Version = $objItem.Version
}
$colItemsCompsys = get-wmiobject -class "Win32_ComputerSystem" -namespace "root\CIMV2" `
-computername $strComputer
foreach ($objItem in $colItemsCompsys)
{
$TotalMemory = $objItem.TotalPhysicalMemory
$Manufacturer = $objItem.Manufacturer
$Model = $objItem.Model
$Domain = $objItem.Domain
}
$colItemsSysEnc = get-wmiobject -class "Win32_SystemEnclosure" -namespace "root\CIMV2" `
-computername $strComputer
foreach ($objItem in $colItemsSysEnc)
{
$SerialNUmber = $objItem.SerialNumber
}
$colItemsProcessor = get-wmiobject -class "Win32_Processor" -namespace "root\CIMV2" `
-computername $strComputer
foreach ($objItem in $colItemsProcessor)
{
$Processor = $objItem.Name
}
$colItemsIP = get-wmiobject -class "Win32_NetworkAdapterConfiguration " -namespace "root\CIMV2" `
-computername $strComputer -Filter "IpEnabled = TRUE"
foreach ($objItem in $colItemsIP)
{
$IPV4 = $objItem.IpAddress
}
$OutputObj = New-Object -Type PSObject
$OutputObj | Add-Member -MemberType NoteProperty -Name ComputerName -Value $strComputer.ToUpper()
$OutputObj | Add-Member -MemberType NoteProperty -Name Name -Value $Name
$OutputObj | Add-Member -MemberType NoteProperty -Name Version -Value $Version
$OutputObj | Add-Member -MemberType NoteProperty -Name TotalPhysicalMemory -Value $TotalMemory
$OutputObj | Add-Member -MemberType NoteProperty -Name Manufacturer -Value $Manufacturer
$OutputObj | Add-Member -MemberType NoteProperty -Name Model -Value $Model
$OutputObj | Add-Member -MemberType NoteProperty -Name Processor -Value $ProcessorSpeed
$OutputObj | Add-Member -MemberType NoteProperty -Name SerialNumber -Value $SerialNo
$OutputObj | Add-Member -MemberType NoteProperty -Name Domain -Value $Domain
$OutputObj | Add-Member -MemberType NoteProperty -Name IPAddress -Value $IPV4
$OutputObj | Export-CSV -NoTypeInformation "c:\powershell\report.txt"
}
im out of ideas now. should i make it into array like?
please advise.
Thank you

Answer 1

The problem is that you are exporting to csv within the loop, so the last item will be the only one showing. Try something like this.
Before the loop:
# Create empty array
$report = #()
At the end of the loop, in place of where you are currently exporting to CSV:
#Add item to report
$report += $OutputObj
Finally, after the end of the loop:
$report | Export-CSV -NoTypeInformation "c:\powershell\report.txt"

I suggest you assign the foreach result to a variable then pipe it to Export-Csv. It should perform faster and is much efficient than recreating, and updating, an array in each loop iteration.
$result = foreach($strComputer in $arrComputers)...
$result | Export-CSV ...
If you used the Foreach-Object' cmdlet to loop over computers you could skip the whole assignment or array creation, processing one object at a time (streamlined) and pipe directly toExport-CSV`:
Get-Content -Path C:\powershell\List.txt | Foreach-Object{
...
} | Export-Csv ...
