ReplicatorActivity.ChildInitialized 事件

  • 参考

定义

命名空间:
System.Workflow.Activities
程序集:
System.Workflow.Activities.dll

紧接在初始化子活动实例后发生。

public:
 event EventHandler<System::Workflow::Activities::ReplicatorChildEventArgs ^> ^ ChildInitialized;
public event EventHandler<System.Workflow.Activities.ReplicatorChildEventArgs> ChildInitialized;
member this.ChildInitialized : EventHandler<System.Workflow.Activities.ReplicatorChildEventArgs> 
Public Custom Event ChildInitialized As EventHandler(Of ReplicatorChildEventArgs)

事件类型

EventHandler<ReplicatorChildEventArgs>

示例

下面的代码示例演示如何设置 ChildInitialized 事件的值。 此代码示例摘自 SimpleReplicatorWorkflow.Designer.cs 文件中的“复制器”SDK 示例。 有关详细信息，请参阅 使用复制器。

public sealed partial class ThrowWorkflow : SequentialWorkflowActivity
{
    [System.Diagnostics.DebuggerNonUserCode()]
    private void InitializeComponent()
    {
        this.CanModifyActivities = true;
        System.Workflow.ComponentModel.ActivityBind activitybind1 = new System.Workflow.ComponentModel.ActivityBind();
        this.throwActivity1 = new System.Workflow.ComponentModel.ThrowActivity();
        activitybind1.Name = "ThrowWorkflow";
        activitybind1.Path = "ThrownException";
        //
        // throwActivity1
        //
        this.throwActivity1.Name = "throwActivity1";
        this.throwActivity1.SetBinding(System.Workflow.ComponentModel.ThrowActivity.FaultProperty, ((System.Workflow.ComponentModel.ActivityBind)(activitybind1)));
        //
        // ThrowWorkflow
        //
        this.Activities.Add(this.throwActivity1);
        this.Name = "ThrowWorkflow";
        this.CanModifyActivities = false;
    }

    private Exception thrownExceptionValue = new System.Exception("My Exception Message.");

    public Exception ThrownException
    {
        get { return thrownExceptionValue; }
        set { thrownExceptionValue = value; }
    }

    private ThrowActivity throwActivity1;
}

Partial Public NotInheritable Class ThrowWorkflow

    End Sub

    Private thrownExceptionValue As New System.Exception("My Exception Message.")

    Public Property ThrownException() As Exception
        Get
            Return thrownExceptionValue
        End Get
        Set(ByVal value As Exception)
            thrownExceptionValue = value
        End Set
    End Property

    Private throwActivity1 As ThrowActivity

End Class

注解

如果已订阅此事件，则每次在为 Children 集合中的项创建子活动的实例时都引发此事件。 Children 集合通过 ReplicatorChildEventArgs 事件处理程序的 Initialized 设置。 在调用中传递子 Activity 实例，以便 ReplicatorActivity 能够设置子级上的值。 还传递 InstanceData 集合中相关的 Children 对象。
