ReplicatorActivity Class

Runs multiple instances of a child activity.

Namespace:  System.Workflow.Activities
Assembly:  System.Workflow.Activities (in System.Workflow.Activities.dll)

[WorkflowDebuggerSteppingAttribute(WorkflowDebuggerSteppingOption.Concurrent)]
[ToolboxBitmapAttribute(typeof(ReplicatorActivity), "Resources.Replicator.png")]
public sealed class ReplicatorActivity : CompositeActivity

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 are canceled.

The following code example shows 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.

workflowRuntime.ServicesExceptionNotHandled += OnExceptionNotHandled;
