Print only property names of PowerShell object

Question

I'm trying to print out only the property names of a Powershell object.
In a script I do an Invoke-RestMethod and Write-Host ($response.result | Format-List | Out-String) gives me a nice list of the $response.result object.
Get-Member -InputObject $response.result also does not display what I want.
$response.result looks something like this: @{id=1; skip=true}. How do I just get a list/table thats shows id, skip etc.
Many thanks!

Answer 1

If the result is just a simple 1-level hashtable, you could do something like:

(@{id=1; skip=$true}).GetEnumerator() | %{ $_.Key }

id
skip

Answer 2

All PowerShell objects have a hidden property PSObject that allows accessing information about the object, e.g. its properties:

$response.result.PSObject.Properties | Select-Object -Expand Name

Answer 3

If it's not a hashtable, you can use Get-Member to find the properties like this:

$response.result | Get-Member -MemberType Properties | Select-Object Name
