Paramètres et Arguments
# doit se situer à la première ligne exécutable (au dessus de Set-StrictMode) param ( # avec une valeur par défaut [string] $Name = "initial value", # paramètre obligatoire # position permet de définir le paramètre sans son nom [Parameter(Mandatory, Position = 0)] [string] $Name, # True par défaut.

Mandatory , demande de manière interactive les paramètres s'ils ne sont pas spécifiés. |
$args fonctionne avec les arguments passés à une fonction mais pas avec ceux passés à un script. |
Validation
param ( [ValidateScript({ Test-Path $_ -PathType Leaf })] # run a command to validate the parameter [string] $FilePath, [ValidateSet('jpg', 'png')] # validate against a list and add auto-completion [string] $ImageFileExtension ) |
