示例

下面的示例演示如何创建 CallExternalMethodActivity 类的实例。 此示例摘自 DocumentApprovalWorkflow.designer.cs 文件中的“PersistenceHost”SDK 示例。 有关详细信息，请参阅 持久性主机示例。

this.SendDocument = new System.Workflow.Activities.CallExternalMethodActivity();

Me.SendDocument = New System.Workflow.Activities.CallExternalMethodActivity()

CallExternalMethodActivity()

初始化 CallExternalMethodActivity 类的新实例。

public:
 CallExternalMethodActivity();

public CallExternalMethodActivity ();

Public Sub New ()

示例

下面的代码示例演示如何初始化 CallExternalMethodActivity 的新实例。 此代码还初始化 ListenActivity, EventDrivenActivity、HandleExternalEventActivity, DelayActivity 和 CodeActivity 类的新实例。 此代码示例摘自 PurchaseOrderWorkflow.Designer.cs 文件中的“侦听”SDK 示例。 有关详细信息，请参阅 侦听示例。

this.CanModifyActivities = true;
this.Timeout = new System.Workflow.Activities.CodeActivity();
this.Delay = new System.Workflow.Activities.DelayActivity();
this.RejectPO = new System.Workflow.Activities.HandleExternalEventActivity();
this.ApprovePO = new System.Workflow.Activities.HandleExternalEventActivity();
this.OnTimeoutEventDriven = new System.Workflow.Activities.EventDrivenActivity();
this.OnOrderRejectedEventDriven = new System.Workflow.Activities.EventDrivenActivity();
this.OnOrderApprovedEventDriven = new System.Workflow.Activities.EventDrivenActivity();
this.POStatusListen = new System.Workflow.Activities.ListenActivity();
this.CreatePO = new System.Workflow.Activities.CallExternalMethodActivity();

Me.CanModifyActivities = True
Me.CreatePO = New System.Workflow.Activities.CallExternalMethodActivity
Me.POStatusListen = New System.Workflow.Activities.ListenActivity
Me.OnOrderApprovedEventDriven = New System.Workflow.Activities.EventDrivenActivity
Me.OnOrderRejectedEventDriven = New System.Workflow.Activities.EventDrivenActivity
Me.OnTimeoutEventDriven = New System.Workflow.Activities.EventDrivenActivity
Me.ApprovePO = New System.Workflow.Activities.HandleExternalEventActivity
Me.RejectPO = New System.Workflow.Activities.HandleExternalEventActivity
Me.Delay = New System.Workflow.Activities.DelayActivity
Me.Timeout = New System.Workflow.Activities.CodeActivity

CallExternalMethodActivity(String)

使用活动名初始化 CallExternalMethodActivity 类的新实例。

public:
 CallExternalMethodActivity(System::String ^ name);

public CallExternalMethodActivity (string name);

new System.Workflow.Activities.CallExternalMethodActivity : string -> System.Workflow.Activities.CallExternalMethodActivity

Public Sub New (name As String)

参数

name

String

用户定义的活动名，用于初始化活动名称属性。
