Reference object property through variable

Question

I'm trying to reference an object property without using Get-Variable.
Anybody know how to do that?

$myObject = New-Object -TypeName PSObject -Property @{
    url                = 'TESTURL'
    webResponse        = ''
}

$objName = 'myObject'

Write-Host Attempt1
(Get-Variable -Name $objName -ValueOnly).url     # this works, yields TESTURL.

Write-Host Attempt2 
$($objName).url    # this fails, $($objName) returns a string instead of an object

I was expecting $($objName) to return an object, but it returns a string instead.

Well, of course, $objName is the name of your object. $myObject.url should work though. — ESG

$objName is string, you defined it yourself as a string. What you do with Get-Variable is getting a variable which is called myObject. The value that you got from Get-Variable is the actual variable of correct type. As pointed already, $myObject.url will work.

Compare it to let's say word apple and the actual fruit

I know $myObject.url will work. But the thing is that I have a number of objects that have an URL property. I also have an array with the object names. I'd like to loop over those names and access the corresponding objects, setting the URL. Preferably without using Get-Variable. Is there no other way?

Nothing is stopping you from doing $variable1 = Get-Varable $name1 and then $variable1.property

You can also use an array of vars or a dictionary and loop
