Using a Powershell noteproperty as a text string in a variable - powershell

Question

I've used Invoke-Restmethod to download some data, which Powershell stores in a PSCustomObject, in a property called data.
I need to use the value of one of the items in the returned data as a variable for another command. I have managed to select-object -expand my way down to the following output from Get-Member:
Name MemberType Definition
---- ---------- ----------
Equals Method bool Equals(System.Object obj)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
ToString Method string ToString()
id NoteProperty System.Int32 id=999
What I need to do is grab the value of the ID noteproperty - 999 - and pass that as part of a string to a new variable, eg:
$newVar = "sometext" + 999 + "moretext"
No amount of select-string or out-string etc is helping. Scripting is not exactly my strong point so I'm not sure I'm even articulating what I want properly - apologies if this is the case!
Any assistance much appreciated

Answer 1

I'm not sure exactly what your code and looks like, so I created the following static approximation from the description:
$data = New-Object PSCustomObject
$data | Add-Member -Type NoteProperty -Name Id -Value 999
$restResponse = New-Object PSCustomObject
$restResponse | Add-Member -Type NoteProperty -Name data -Value $data
Please clarify if this is not a match. You can get the Id value as follows
$restResponse.data.Id
Assign it to another variable
$newVar = "sometext" + $restResponse.data.Id + "moretext"
$newVar
And if your REST response is a collection of data objects, iterate through them
$restResponse.data | Foreach-Object { "sometext" + $_.Id + "moretext" }

I would go for for using $output | select *,#{n='test';e={[string]$_.test}} -exclude properties test
if the exclude is not active it will complain about it already exists. Mostly I use the select expression to manipulate data realtime instead of psCustomObject for such simple task
