Using Activities to Control Flow
Windows Workflow Foundation includes a set of activities that provide varied functionality. You can use some of these activities to control the logical flow of a workflow. For a complete list of the activities in the Windows Workflow Foundation base activity library, see Windows Workflow Foundation Activities.
The following table lists the activities in the Windows Workflow Foundation base activity library that are used to control workflow logical flow.
| Activity | Description |
|---|---|
Enables your workflow to branch conditionally depending on some event or on the expiration of a time-out period. For more information, see Using the ListenActivity Activity. |
|
Tests a condition on each branch and performs activities on the first branch for which the condition equals True. For more information, see Using the IfElseActivity Activity. |
|
Enables your workflow to perform two or more operations independently of each other. For more information, see Using the ParallelActivity Activity. |
|
Suspends the operation of your workflow to enable intervention in the event of some error condition. For more information, see Using the SuspendActivity Activity. |
|
Enables you to immediately end the operation of your workflow in the event of some error condition. For more information, see Using the TerminateActivity Activity. |
|
Enables your workflow to loop until a condition is met. For more information, see Using the WhileActivity Activity. |
|
Also known as CAG. Executes child activities based on a condition that applies to the CAG itself, and based on conditions that apply separately to each child activity. For more information, see Using the ConditionedActivityGroup Activity. |
|
Wraps another activity and executes it when the specified event occurs. For more information, see Using the EventDrivenActivity Activity. |
|
Creates and executes multiple instances of a child activity. For more information, see Using the ReplicatorActivity Activity. |
|
Runs a set of child activities according to a single defined ordering. For more information, see Using the SequenceActivity Activity. |
