I have an array of hashtables $a (I give a very simplyfied example):

$a = @()
$a += @{id=1; name='Aron' }
$a += @{id=2; name='Benny'}
$a

Result:

Name                           Value
----                           -----
id                             1
name                           Aron
id                             2
name                           Benny

I try to serialize and then deserialize it, using the json fonctionality in Powershell 5.1:

$b = $a | ConvertTo-Json | ConvertFrom-Json

but the two objects are not the same, which is the goal.

$b

Result:

id name
-- ----
 1 Aron
 2 Benny

The types are the same:

$a.getType()
$b.getType()

Result:

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

I’ve tried all kind of combinations of getEnumerator() and out-string, with no succes.

What to do to use jSON conversion back and forth, and get the same array of hashtables in the end?

The reason I need this: the JSON conversion should save the serialized array in a file and be able to fetch it and deserialize it later.
