示例

下面的代码示例演示如何创建 HandleExternalEventActivity 类并设置其值。 此代码示例摘自 DocumentApprovalWorkflow.cs 文件中的“RaiseEventToLoadWorkflow”SDK 示例。 有关详细信息,请参阅 引发事件以加载工作流

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);
Me.Car.Name = "Car"
AddHandler Car.ExecuteCode, AddressOf Me.Car_ExecuteCode
Me.Car.SetValue(System.Workflow.Activities.ConditionedActivityGroup.WhenConditionProperty, codecondition1)
AddHandler codecondition2.Condition, AddressOf Me.AirlineCondition
