PowerShell Help

Hello,

I have CSV1 (as below) where I have to populate the last column from CSV 2 given below…

CSV1

[pre]
Computer Product Code Country Department LaptopDesktop

Com1 EliteDesk 705 HP2190 AU FN
Com2 EliteBook 830 HP1023 AU IT
Com3 EliteBook 830 HP1023 FR FN
Com4 Zbook 15U HP2020 IN FN
Com5 OptiPlex 3010 DL1721 FR FN
[/pre]

CSV2
[pre]
Product Type Code

EliteBook 1030 L HP1020
EliteBook 1040 L HP1021
EliteBook 830 L HP1023
Zbook 15U L HP2020
EliteDesk 800 D HP3035
EliteDesk 705 D HP2190
Thinkpad L480 L LE990
OptiPlex 3010 D DL1721
[/pre]

with below code, I’m unable to update ‘LaptopDesktop’ column in CSV1 whereas output gets appended with -Append parameter or without that, it just overwrite the whole CSV…How do I fix this?
[pre]
function Update-SystemType {
{
$SystemData =@()
$Productinfo = Import-Csv “C:\CSV2.csv”
$Mastercsv = Import-Csv “C:\CSV1.csv”

foreach($record in $Mastercsv)
{
$mcode = $($record.code)
$mDLtype = $($record.LaptopDesktop)

$SysType = ($Productinfo | where {$_.code -eq $mcode}).type
if ($SysType -eq $null)
{
$sysType = ‘Unknown, due to non-matching code’
}

$AddsysType=New-Object PSCustomObject
Add-Member -InputObject $AddsysType -membertype noteproperty -name “LaptopDesktop” -value $sysType
$SystemData +=$AddsysType

}Return, $SystemData
}
[/pre]
