Esempio

Nell'esempio seguente viene creato un pacchetto, viene aggiunto un oggetto ForEachLoop e viene aggiunta una variabile alla Variables raccolta di ForEachLoop . Vengono quindi recuperate e impostate proprietà sulla variabile e visualizzate per la visualizzazione, incluso il Name .

static void Main(string[] args)  
        {

            ForEachLoop feLoop = (ForEachLoop)seq.Executables.Add("STOCK:FOREACHLOOP");

           // of the ForEach loop.

Esempio di output

Le proprietà della variabile sono:

Nome creazione =

Description = Descrizione nuova v

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

Nome precedente, nuovo nome = v, my_new_V_name

Vecchio spazio dei nomi, nuovo spazio dei nomi = globale, my_new_v_Namespace

Conteggio proprietà = 12

Nome completo = my_new_v_Namespace:: my_new_V_name

RaiseEvent precedente, nuovo RaiseEvent = false, true

vecchio di sola lettura, nuovo di sola lettura = false, true

Variabile di sistema = false

Tipo = Int32
