Exemplos
O exemplo a seguir demonstra a adição de atividades à propriedade TransientWorkflow. Este exemplo é do exemplo do SDK do Computador de Estado de Ordenação. Para obter mais informações, consulte Ordenando o exemplo do computador de estado.
// 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);
