範例

下列程式碼範例示範如何設定 ChildInitialized 事件的值。 這個程式碼範例是 SimpleReplicatorWorkflow.Designer.cs 檔案中＜複寫器 SDK＞範例的一部分。 如需詳細資訊，請參閱 使用複寫器。

    [System.Diagnostics.DebuggerNonUserCode()]

        this.throwActivity1 = new System.Workflow.ComponentModel.ThrowActivity();

備註

如果有訂閱這個事件，每次為 Children 集合中的項目建立子活動的執行個體時，即引發這個事件。 Children 集合是透過 ReplicatorChildEventArgs 事件處理常式的 Initialized 完成設定。 子 Activity 執行個體會透過該呼叫傳遞，如此 ReplicatorActivity 便能夠在該子執行個體上設定值。 InstanceData 集合中的相關 Children 物件也會跟著傳遞。
