Unable to export custom objects to CSV in powershell - powershell

Question

I have written powershell scirpt to generate IIS information to CSV.
$bindingip = Get-WmiObject -Namespace root\webadministration -Class sslbinding2 | Select-Object -
Property PSComputerName,IPAddress
$sitedetails = Get-Website | Select-Object -Property Name,ID,State
$report = New-Object psobject
$report | Add-Member -MemberType NoteProperty -Name "Hostname" -Value $bindingip.PSComputerName
$report | Add-Member -MemberType NoteProperty -Name "IPAddress" -Value $bindingip.IPAddress
$report | Add-Member -MemberType NoteProperty -Name "Site Name" -Value $sitedetails.name
$report | Add-Member -MemberType NoteProperty -Name "ID" -Value $sitedetails.id
$report | Add-Member -MemberType NoteProperty -Name "State" -Value $sitedetails.state
$report | Export-Csv C:\content.csv -NoTypeInformation
Output of CSV:
Hostname IPAddress Site Name ID State
System.Object[] System.Object[] System.Object[] System.Object[] System.Object[]
Do i need to add anything to the code to get exact output, Can anyone help on this.

Answer 1

As Abraham and Ash pointed out in their comments, the values of the properties on your variables $bindingip and $sitedetails are an array instead of a string. This is why when you export the report you get the object type instead of it's actual value.
You could see this by doing for example this:
$bindingip.PSComputerName.GetType()
Which would return something like this:
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True Object[] System.Array
However if you select just the first element on the array PSComputerName
$bindingip.PSComputerName[0].GetType()
You would see:
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True String System.Object
A workaround for this, is to either convert the values to a multiline string by the use of Out-String or by joining the elements of the arrays with a delimiter i.e. -join '//'.
$bindingip = Get-WmiObject -Namespace root\webadministration -Class sslbinding2
$sitedetails = Get-Website
# Like this (thanks mklement0):
$report = [pscustomobject]#{
Hostname = "$($bindingip.PSComputerName)"
IPAddress = "$($bindingip.IPAddress)"
'Site Name' = "$($sitedetails.name)"
ID = "$($sitedetails.id)"
State = "$($sitedetails.state)"
}
# Or like this:
$report = [pscustomobject]#{
Hostname = ($bindingip.PSComputerName | Out-String).trim()
IPAddress = ($bindingip.IPAddress | Out-String).trim()
'Site Name' = ($sitedetails.name | Out-String).trim()
ID = ($sitedetails.id | Out-String).trim()
State = ($sitedetails.state | Out-String).trim()
}
# Or like this:
$report = [pscustomobject]#{
Hostname = $bindingip.PSComputerName -join '//'
IPAddress = $bindingip.IPAddress -join '//'
'Site Name' = $sitedetails.name -join '//'
ID = $sitedetails.id -join '//'
State = $sitedetails.state -join '//'
}
$report | Export-Csv C:\content.csv -NoTypeInformation
Edit
This can also work, which is what I think mklement0 suggested. It will create a new object for each element on the values of the properties:
$compName = $bindingip.PSComputerName
$ipAddr = $bindingip.IPAddress
$name = $sitedetails.name
$id = $sitedetails.id
$state = $sitedetails.state
$top = ($compName.Count,$ipAddr.Count,$name.Count,$id.Count,$state.Count | Measure-Object -Maximum).Maximum
$report = for($i = 0;$i -lt $top;$i++)
{
[pscustomobject]#{
Hostname = $compName[$i]
IPAddress = $ipAddr[$i]
'Site Name' = $name[$i]
ID = $id[$i]
State = $state[$i]
}
$report | Export-Csv...

In addition to Santiago's very thorough and excellent answer, it appears to me that we are just combining the objects of one array with another to produce all possible combinations. I might do something like the following to accomplish this.
$bindingip = #(
[PSCustomObject]#{
PSComputerName = 'Public1'
IPAddress = '192.168.0.1'
},
[PSCustomObject]#{
PSComputerName = 'Public1'
IPAddress = '127.0.0.1'
}
)
$siteDetails = #(
[PSCustomObject]#{
Name = 'site 1'
Id = 'site1'
State = 'up'
},
[PSCustomObject]#{
Name = 'site 2'
Id = 'site2'
State = 'down'
}
)
$combined = foreach ($ip in $bindingip) {
foreach ($details in $siteDetails) {
$out = [ordered]#{}
$ip.psobject.properties | ForEach-Object {
$out[$_.Name] = $_.Value
}
$details.psobject.properties | ForEach-Object {
$out[$_.Name] = $_.Value
}
[pscustomobject]$out
}
}
$combined | Format-Table
Output
PSComputerName IPAddress Name Id State
-------------- --------- ---- -- -----
Public1 192.168.0.1 site 1 site1 up
Public1 192.168.0.1 site 2 site2 down
Public1 127.0.0.1 site 1 site1 up
Public1 127.0.0.1 site 2 site2 down
One might wrap this in a function for reusability
function Combine-ObjectsFromTwoArrays {
param (
[array]$array1,
[array]$array2
)
foreach ($obj1 in $array1) {
foreach ($obj2 in $array2) {
$out = [ordered]#{}
$obj1.psobject.properties | ForEach-Object {
$out[$_.Name] = $_.Value
}
$obj2.psobject.properties | ForEach-Object {
$out[$_.Name] = $_.Value
}
[pscustomobject]$out
}
}
}
