WorkflowChanges.TransientWorkflow Propriété

Définition

Retourne une arborescence d’activité clonée à laquelle des modifications peuvent être apportées puis appliquées à l’instance de workflow en cours d’exécution.

public:
 property System::Workflow::ComponentModel::CompositeActivity ^ TransientWorkflow { System::Workflow::ComponentModel::CompositeActivity ^ get(); };
public System.Workflow.ComponentModel.CompositeActivity TransientWorkflow { get; }
member this.TransientWorkflow : System.Workflow.ComponentModel.CompositeActivity
Public ReadOnly Property TransientWorkflow As CompositeActivity

Valeur de propriété

CompositeActivity

Un CompositeActivity qui contient l'activité racine clonée pour le workflow.

Exemples

L'exemple suivant montre des activités d'ajout à la propriété TransientWorkflow. Cet exemple provient de l'exemple du Kit de développement logiciel Ordering State Machine (SDK). Pour plus d’informations, consultez l’exemple Ordering State Machine.

// Create a new instance of the WorkflowChanges class for managing
// the in-memory changes to the workflow
WorkflowChanges changes = new WorkflowChanges(root);

// Create a new State activity to the workflow
StateActivity orderOnHoldState = new StateActivity();
orderOnHoldState.Name = "OrderOnHoldState";

// Add a new EventDriven activity to the State
EventDrivenActivity eventDrivenDelay = new EventDrivenActivity();
eventDrivenDelay.Name = "DelayOrderEvent";
orderOnHoldState.Activities.Add(eventDrivenDelay);

// Add a new Delay, initialized to 5 seconds
DelayActivity delayOrder = new DelayActivity();
delayOrder.Name = "delayOrder";
delayOrder.TimeoutDuration = new TimeSpan(0, 0, 5);
eventDrivenDelay.Activities.Add(delayOrder);

// Add a new SetState to the OrderOpenState
SetStateActivity setStateOrderOpen = new SetStateActivity();
setStateOrderOpen.TargetStateName = "OrderOpenState";
eventDrivenDelay.Activities.Add(setStateOrderOpen);

// Add the OnHoldState to the workflow
changes.TransientWorkflow.Activities.Add(orderOnHoldState);
