L’exemple suivant crée un package, ajoute un ForEachLoop et ajoute une variable à la Variables collection de ForEachLoop . Il récupère ensuite et définit les propriétés de la variable et les affiche pour les afficher, y compris le Name .

           // of the ForEach loop.

Exemple de sortie :

Les propriétés de la variable sont les suivantes :

Nom de la création =

Description = ma nouvelle description v

ID = {622CF328-55D7-4E81-9385-9C1F8450511E}

Ancien nom, nouveau nom = v, my_new_V_name

Ancien espace de noms, nouvel espace de noms = global, my_new_v_Namespace

Nombre de propriétés = 12

Nom qualifié = my_new_v_Namespace :: my_new_V_name

Old RaiseEvent, New RaiseEvent = false, true

ancien en lecture seule, nouveau lecture seule = false, true

Variable système = false

Type = Int32
