I have a Powershell function that returns an array of hashtables. If the function returns a single entry in the array, then I get some odd behaviour, is this expected?

For context:

• I’m a C# developer, so I’m expecting the return type to be consistent, regardless of the quantity of results 🙂
• Powershell Version: 5.1 on Windows 11

function GetArrayOfHashtable
{
    param([string] $name, [int]$count)
    $result = @()
    for ($i = 0; $i -lt $count; $i++) {
        $h = @{
            name = $name
            id=$i+1
        }
        $result += $h
    }
    return $result
}

$one = GetArrayOfHashtable "one" 1
$two = GetArrayOfHashtable "two" 2
$three = GetArrayOfHashtable "three" 3

Write-Host $one.gettype()     # 'System.Collections.Hashtable'  <--???
Write-Host $two.gettype()     # 'System.Object[]'
Write-Host $three.gettype()   # 'System.Object[]'

Write-Host $three[0].name  $three[0].id  # 'three 1'
Write-Host $two[0].name  $two[0].id      # 'two 1'
Write-Host $one[0].name  $one[0].id      # '' 

Update (for completeness)
I can work around the issue by encapsulating the array of hashtables in another hashtable:

function GetArrayOfHashtable
{
    param([string] $name, [int]$count)
    $result = @()
    for ($i = 0; $i -lt $count; $i++) {
        $h = @{
            name = $name
            id=$i+1
        }
        $result += $h
    }
    return @{data =$result}  # NOTE: solution is to hold the result in a hashtable
}

$one = GetArrayOfHashtable "one" 1
$two = GetArrayOfHashtable "two" 2
$three = GetArrayOfHashtable "three" 3

Write-Host $one.data.gettype()     # 'System.Object[]'
Write-Host $two.data.gettype()     # 'System.Object[]'
Write-Host $three.data.gettype()   # 'System.Object[]'

Write-Host $three.data[0].name  $three.data[0].id  # 'three 1'
Write-Host $two.data[0].name  $two.data[0].id      # 'two 1'
Write-Host $one.data[0].name  $one.data[0].id      # 'one 1'
