ReplicatorActivity Class

Runs multiple instances of a child activity.

Namespace: System.Workflow.Activities
Assembly: System.Workflow.Activities (in system.workflow.activities.dll)

public sealed class ReplicatorActivity : CompositeActivity
public final class ReplicatorActivity extends CompositeActivity
public final class ReplicatorActivity extends CompositeActivity
Not applicable.

The ReplicatorActivity is similar to a For Each statement in code. If you are presented with a task in which you repeat the same function on many different entities, ReplicatorActivity may be a better solution than WhileActivity.

By default, a ReplicatorActivity is completed when all child instances have completed. You can override this behavior with a custom condition to use when the activity finishes. If this condition evaluates to true before all child instances have completed, then any running incomplete child instances will be canceled.

The following code example demonstrates how to create a new instance of the ReplicatorActivity class and define a handler for the Initialized event. This code example is part of the Replicator SDK Sample from the SimpleReplicatorWorkflow.Designer.cs file. For more information, see Using Replicator.

using System.Workflow.Activities;

namespace Microsoft.Samples.Workflow.SimpleReplicator
    public sealed partial class SimpleReplicatorWorkflow
        private void InitializeComponent()
            this.CanModifyActivities = true;
            System.Workflow.ComponentModel.ActivityBind activityBind1 = new System.Workflow.ComponentModel.ActivityBind();
            this.SampleReplicatorChildActivity1 = new Microsoft.Samples.Workflow.SimpleReplicator.SampleReplicatorChildActivity();
            this.ReplicatorWork = new System.Workflow.Activities.ReplicatorActivity();
            // SampleReplicatorChildActivity1
            this.SampleReplicatorChildActivity1.InstanceData = null;
            this.SampleReplicatorChildActivity1.Name = "SampleReplicatorChildActivity1";
            activityBind1.Name = "SimpleReplicatorWorkflow";
            activityBind1.Path = "ChildData";
            // ReplicatorWork
            this.ReplicatorWork.ExecutionType = System.Workflow.Activities.ExecutionType.Sequence;
            this.ReplicatorWork.Name = "ReplicatorWork";
            this.ReplicatorWork.ChildInitialized += new System.EventHandler<System.Workflow.Activities.ReplicatorChildEventArgs>(this.ChildInitializer);
            this.ReplicatorWork.SetBinding(System.Workflow.Activities.ReplicatorActivity.InitialChildDataProperty, ((System.Workflow.ComponentModel.ActivityBind)(activityBind1)));
            // SimpleReplicatorWorkflow
            this.Name = "SimpleReplicatorWorkflow";
            this.CanModifyActivities = false;


        private SampleReplicatorChildActivity SampleReplicatorChildActivity1;
        private ReplicatorActivity ReplicatorWork;
