HashMap in PowerShell

I am facing issues while implementing a HashMap in PowerShell. I have created the HasMap from a ReST reponse using 

$response_connection_hashmap = $response_connection|foreach {
@{  $_.name = $_.id }
}

I am successfully verifying the hasmap using

$response_connection_hashmap.GetEnumerator()|Sort-Object Name

However while searching for a value by key, I am using below

$response_connection_hashmap.Item("Key01")

Getting below error

Exception getting "Item": "Cannot convert argument "index", with value: 
"Key01", for "get_Item" to type "System.Int32": "Cannot convert value 
"Key01" to type "System.Int32". Error: "Input string was not in a correct 
format."""

You are generating an array of hashtables:

$response_connection_hashmap.GetType()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     Object[]                                 System.Array

Try this instead:

$response_connection_hashmap = @{}
$response_connection|foreach { $response_connection_hashmap.add($_.name, $_.id) }
