WorkflowChanges.TransientWorkflow Eigenschaft

Definition

Namespace:

System.Workflow.ComponentModel

Assembly:

System.Workflow.ComponentModel.dll

Gibt eine geklonte Aktivitätsstruktur zurück, an der Änderungen möglich sind, die anschließend für die ausgeführte Workflowinstanz übernommen werden können.

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

Eigenschaftswert

CompositeActivity

Eine CompositeActivity, die die geklonte Stammaktivität für den Workflow enthält.

Beispiele

Im folgenden Beispiel wird das Hinzufügen von Aktivitäten zur TransientWorkflow-Eigenschaft gezeigt. Dieses Beispiel stammt aus dem Ordering State Machine SDK-Beispiel. Weitere Informationen finden Sie unter Beispiel zum Sortieren des Zustandscomputers.

// 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);
