How to output Azure Virtual Network Subnets to csv using powershell for single or multiple subscriptions - azure

Question

I am new to powershell and trying to output subnet information for Azure Virtual Networks in either single or multiple subscriptions.
I can output to the console and get the results I'm looking for but struggling to get the same output to a csv file.
I understand that I need to create New Objects, etc. but can't get the correct syntax to work.
Could anyone help please.
Working code below....
$subs = Get-AzSubscription -SubscriptionID xxxxxxxxxxxxxxxx
foreach ($Sub in $Subs) {
$SelectSub = Select-AzSubscription -SubscriptionName $Sub.Name
$VNETs = Get-AzVirtualNetwork
foreach ($VNET in $VNETs) {
$Sub.Name
$VNET.Name
($VNET).AddressSpace.AddressPrefixes
($VNET).Subnets.Name
Write-Host " "
}
}

I think something like this will do the trick:
$subs = Get-AzSubscription -SubscriptionID xxxxxxxxxxxxxxxx
foreach ($Sub in $Subs) {
Select-AzSubscription -SubscriptionName $Sub.Name | Out-Null
$networks = Get-AzVirtualNetwork | ForEach-Object {
New-Object PSObject -Property #{
name = $_.name
subnets = $_.subnets.name -join ';'
addressSpace = $_.AddressSpace.AddressPrefixes -join ';'
}
}
$networks | Export-Csv -NoTypeInformation file.csv
}
edit: previous version didnt really work, export-csv is a bit weird, i guess.
