Error adding to array: Cannot find an overload for "Add" and the argument count: "1&q-CodePudding

I can't for the life of me work out how to add elements to an array inside a foreach loop. I keep getting the error:

   8 |      $logs.Add(@{
     |      ~~~~~~~~~~~~
     | Cannot find an overload for "Add" and the argument count: "1".
MethodException: C:\Users\michael.dawson\OneDrive - Sage Software, Inc\Documents\Source_Control\secrets-dashboard-script\function\Calculate\recreate-error2.ps1:8:5

I can get it to work outside of a foreach, but I've been scratching my head for ages :-( Here's the code:

$logs = New-Object System.Collections.ArrayList
$logs = $null
$logs = @{}

Get-Service | ForEach-Object {
    $appCreds = $_

    $logs.Add(@{
        "test"      = $appCreds.DisplayName;
        "message"   = "blah"
    })
}  

$logs | ConvertTo-Json -Depth 10

Appreciate any help guys. Cheers.

I'm expecting some JSON a bit like this:

  {
    "message": "blah",
    "test": "Optimise drives"
  },
  {
    "message": "blah",
    "test": "Dell Client Management Service"
  },
  {
    "message": "blah",
    "test": "DeviceAssociationBroker_1592b90"
  }

Try the following:

$logs = 
  Get-Service |
  ForEach-Object {
    @{
      test    = $_.DisplayName;
      message = "blah"
    }
  }  

$logs | ConvertTo-Json -Depth 10

I am in rush but, I want to help. Try the example below.

$logs = New-Object System.Collections.ArrayList

Get-Service | ForEach-Object {
    $appCreds = $_

    $logs.Add(@{
        "test"      = $appCreds.DisplayName;
        "message"   = "blah"
    }) | out-null
}
