Pass object[] into a function in PowerShell

Question

Is there a resource on how to pass in a Object[] as a parameter within a PowerShell function?

Both of these functions are cmdlets and they are being exported correctly, but I cannot see the $Return object in my second function.

Is something like the following needed?

ParameterAttribute.ValueFromPipeline Property (System.Management.Automation)

# Within PowerShell code $Return = My-Function -Param "value" # $Return is of type Object[] $ModifiedReturn = My-SecondFunction -Input $Return

Where this is my function definition:

function My-SecondFunction { [CmdletBinding()] Param( [Parameter(Mandatory=$True)] [Object[]]$Input ) begin {} process { Write-Host "test: $Input" # Does not return anything } end {} }

$Input is the name of an automatic variable. Use a different name.

I recommend $InputObject as that is in common usage so it has a well-understood meaning, but usually that means you are accepting pipeline input as well.

Of course if there's a name that's more descriptive for this parameter, you should use that.

I have submitted this issue on the PowerShell GitHub project suggesting that Set-StrictMode be modified to check for automatic variable assignment.
