PowerShell Module Parameter can't pipe ADUser Array-CodePudding

i have the following Situation: Im trying to create a PS Module to export ADUsers to an excel file as .xlsx file, as a own function. When i pipe a Get-ADUser command to my Parameter, i do not get the whole users, i do only get the last one. I have declared the inputvariable as ADAcount Object and also as array..

Hier is my Code in extra short format:

Function Export-Excel
{
   [cmdletBinding()]
   param(
       [parameter(ValueFromPipeline)]
       [Microsoft.ActiveDirectory.Management.ADAcount[]] $Users  

   )

   Write-Host $Users.count




...........

}

When i now call the function via powershell it looks like:

Get-ADUser -Filter * -Properties * | Export-Excel

# Output: 1
# And this one is an ADUser Object, the last created one / the last one in the array...

# When i do this:
$user = Get-ADUser -Filter * -Properties *
Write-Host $user.count

# Output: 2500

I hope you understand my problem :)

Thanks a lot and have nice christmas time :)

If you want to pipe all your user objects, import and work with the total (for reporting) you'll need to use the Begin, Process, and End keywords as detailed in get-help about_functions, for example:

Function Export-Excel {
    [cmdletBinding()]
    param(
        [parameter(ValueFromPipeline)]
        [Microsoft.ActiveDirectory.Management.ADUser[]]$Users
    )
    begin {
        $usersArray = @()
    }
    process {
        foreach ($user in $Users) {
            $usersArray  = $user
        }
    }
    end {
        Write-Host $usersArray.count
    }
   
}


Get-ADUser -Filter * -Properties * | Export-Excel

I did do, a bit, research, and found: Powershell Array parameter from pipline

Then I changed your script, a little, because I do not have an AD:

Function EE
{
   [cmdletBinding()]
   param(
       [parameter(Mandatory=$true, ValueFromPipeline=$true)]
       #[Microsoft.ActiveDirectory.Management.ADAcount[]] $Users  
       [string[]]$Users   
   )

   process {
       write-Host $Users
   }

}

Get-LocalUser | EE

The explanation is: The "process" block is run once for each item in the pipeline.

This will get me a list of all my local users.
