Exemple de code Runspace01 (VB.NET)

Voici les exemples de code de l’espace d’exécution décrits dans Création d’une application console qui exécute une commande spécifiée. Pour ce faire, l’application appelle un runspace, puis appelle une commande. (Notez que cette application ne spécifie pas d’informations de configuration d’instance d’exécution, ni ne crée explicitement un pipeline.) La commande appelée est l’applet de commande Get-Process.
