L’exemple suivant héberge un workflow à l’aide de WorkflowApplication. Une WorkflowApplication instance est construite à l’aide d’une définition de flux de travail composée d’une seule DiceRoll activité. L’activité DiceRoll a deux arguments de sortie qui représentent les résultats de l’opération de lancement de dés. Une fois le flux de travail terminé, les sorties sont récupérées dans le Completed gestionnaire et la sortie suivante s’affiche dans la console.

Workflow aae3fb48-7229-4737-b969-d63e131b96b3 Completed.
The two dice are 1 and 5.

public sealed class DiceRoll : CodeActivity

    public OutArgument<int> D1 { get; set; }
    public OutArgument<int> D2 { get; set; }

    static Random r = new Random();

    {
        D1.Set(context, r.Next(1, 7));
        D2.Set(context, r.Next(1, 7));
    }
}

 // Create a WorkflowApplication instance.
 WorkflowApplication wfApp = new WorkflowApplication(new DiceRoll());

 // Subscribe to any desired workflow lifecycle events.

Exemples

L’exemple suivant héberge un workflow à l’aide de WorkflowApplication. Une WorkflowApplication instance est construite à l’aide d’une définition de flux de travail composée d’une seule Divide activité qui accepte deux arguments d’entrée et un dictionnaire d’arguments d’entrée contenant les deux valeurs à transmettre, clé par nom d’argument. Les événements de cycle de vie de flux de travail souhaités sont gérés et le flux de travail est appelé avec un appel à Run. Une fois le flux de travail terminé, la sortie suivante s’affiche dans la console.
