Esempio

Nel codice seguente viene illustrato come connettere un gestore eventi Condition per l'istanza corrente di CodeCondition. Questo esempio di codice è parte dell'esempio SDK ConditionedActivityGroup nel file SimpleCAGWorkflow.designer.cs. Per altre informazioni, vedere Uso di ConditionedActivityGroup.

this.CanModifyActivities = true;
System.Workflow.Activities.CodeCondition codecondition1 = new System.Workflow.Activities.CodeCondition();
System.Workflow.Activities.CodeCondition codecondition2 = new System.Workflow.Activities.CodeCondition();
this.BookingCag = new System.Workflow.Activities.ConditionedActivityGroup();
this.Car = new System.Workflow.Activities.CodeActivity();
this.Airline = new System.Workflow.Activities.CodeActivity();
//
// BookingCag
//
this.BookingCag.Activities.Add(this.Car);
this.BookingCag.Activities.Add(this.Airline);
this.BookingCag.Name = "BookingCag";
codecondition1.Condition += new System.EventHandler<System.Workflow.Activities.ConditionalEventArgs>(this.CarCondition);
//
// Car
//
this.Car.Name = "Car";
this.Car.ExecuteCode += new System.EventHandler(this.Car_ExecuteCode);
this.Car.SetValue(System.Workflow.Activities.ConditionedActivityGroup.WhenConditionProperty, codecondition1);
codecondition2.Condition += new System.EventHandler<System.Workflow.Activities.ConditionalEventArgs>(this.AirlineCondition);
