Function CustomObjectWithMethodParameter
{
    $CustomObject = New-Object PSObject
    $CustomObject | Add-Member -MemberType ScriptMethod -Name testParam -Value {
        param
        (
            [String]$parameter01 = $(throw "parameter01 must be specified.")
        )

        Write-Host "Parameter01 value: $parameter01"
    }

    $CustomObject
}

$myobj = CustomObjectWithMethodParameter
$myobj.testParam("Hello World.")
