IActivityTemplateFactory 接口

定义

命名空间:

System.Activities.Presentation

程序集:

System.Activities.Presentation.dll

定义工厂方法，类实现该方法来创建封装“占位符”Activity 对象的模板。

public interface class IActivityTemplateFactory

public interface IActivityTemplateFactory

type IActivityTemplateFactory = interface

Public Interface IActivityTemplateFactory

派生

System.Activities.Core.Presentation.Factories.ForEachWithBodyFactory<T>

System.Activities.Core.Presentation.Factories.ParallelForEachWithBodyFactory<T>

System.Activities.Core.Presentation.Factories.PickWithTwoBranchesFactory

System.Activities.Core.Presentation.Factories.StateMachineWithInitialStateFactory

System.Activities.Presentation.Toolbox.ActivityTemplateFactory

System.ServiceModel.Activities.Presentation.Factories.ReceiveAndSendReplyFactory

System.ServiceModel.Activities.Presentation.Factories.SendAndReceiveReplyFactory

示例

public sealed class MyDelayActivity : IActivityTemplateFactory  

{  
     public Activity Create(DependencyObject target)  
     {  
         return new System.Activities.Statements.Delay  
         {  
             DisplayName = "DelayActivityTemplate",  
             Duration = new TimeSpan(0,0,10)  

         };  
     }  
 }  

注解

自定义活动模板必须实现 IActivityTemplateFactory。 自定义活动模板用于自定义活动的配置（包括自定义复合活动），这样用户就不必单独创建每个活动并手动配置它们的所有属性和其他设置。

方法

Create(DependencyObject)

创建 Activity 类的实例，该类表示指定目标对象的预定义设计模式。
