Примеры

В следующем примере показано, как добавлять действия в свойство TransientWorkflow. Это пример из примера SDK "Ordering State Machine". Дополнительные сведения см. в разделе Упорядочение примера конечного автомата.

// 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);
