Legacy Workflow Activities
Windows Workflow Foundation (WF) includes a default set of activities that provide functionality for control flow, conditions, event handling, state management, and communicating with applications and services. When designing workflows, you can use the system-provided activities that are provided by the Windows Workflow Designer, or you can create your own custom activities.
The following table lists the Windows Workflow Foundation framework out-of-box activity set. Many, but not all, of these activities are represented by activity designers that can be accessed from the Toolbox of the Workflow-Designer. To create an activity, drag its designer from the Toolbox and drop it on the design surface.
| Activity | Description |
|---|---|
Used with the HandleExternalEventActivity activity for input and output communications with a local service. Weitere Informationen finden Sie unter Using the CallExternalMethodActivity Activity. |
|
Used to contain cleanup logic for a composite activity canceled before all the composite activity's children are finished executing. Weitere Informationen finden Sie unter Using the CancellationHandlerActivity Activity. |
|
Enables you to add Visual Basic or C# code to your workflow. Weitere Informationen finden Sie unter Using the CodeActivity Activity. |
|
A compensatable version of SequenceActivity. Weitere Informationen finden Sie unter Using the CompensatableSequenceActivity Activity. |
|
A compensatable version of TransactionScopeActivity. Weitere Informationen finden Sie unter Using the CompensatableTransactionScopeActivity Activity. |
|
Enables you to call code to undo or to compensate for operations already performed by the workflow when an error occurs. Weitere Informationen finden Sie unter Using the CompensateActivity Activity. |
|
A wrapper for one or more activities that perform compensation for a completed TransactionScopeActivity activity Weitere Informationen finden Sie unter Using the CompensationHandlerActivity Activity. |
|
Executes child activities based on a condition that applies to the ConditionedActivityGroup activity itself and based on conditions that apply separately to each child. Weitere Informationen finden Sie unter Using the ConditionedActivityGroup Activity. |
|
Enables you to build delays in your workflow that are based on a time-out interval. Weitere Informationen finden Sie unter Using the DelayActivity Activity. |
|
Wraps one or more activities that are executed when a specified event occurs. Weitere Informationen finden Sie unter Using the EventDrivenActivity Activity. |
|
Provides a framework for associating events with an activity. Weitere Informationen finden Sie unter Using the EventHandlersActivity Activity. |
|
Executes its main child activity concurrently with an EventHandlersActivity. Weitere Informationen finden Sie unter Using the EventHandlingScopeActivity Activity. |
|
Used to handle an exception of a type that you specify. Weitere Informationen finden Sie unter Using the FaultHandlerActivity Activity. |
|
Represents a composite activity that has an ordered list of child activities of type FaultHandlerActivity. Weitere Informationen finden Sie unter Using the FaultHandlersActivity Activity. |
|
Used in conjunction with the CallExternalMethodActivity activity for input and output communications with a local service. Weitere Informationen finden Sie unter Using the HandleExternalEventActivity Activity. |
|
Tests a condition on each branch and performs activities on the first branch for which the condition equals true. Weitere Informationen finden Sie unter Using the IfElseActivity Activity. |
|
Represents a branch of an IfElseActivity. Weitere Informationen finden Sie unter Using the IfElseBranchActivity Activity. |
|
Enables your workflow to invoke a Web service. Weitere Informationen finden Sie unter Using the InvokeWebServiceActivity Activity. |
|
Enables your workflow to invoke another workflow. Weitere Informationen finden Sie unter Using the InvokeWorkflowActivity Activity. |
|
A composite activity that contains only EventDrivenActivity child activities. Weitere Informationen finden Sie unter Using the ListenActivity Activity. |
|
Provides a way to schedule two or more child SequenceActivity activity branches for processing at the same time. Weitere Informationen finden Sie unter Using the ParallelActivity Activity. |
|
Use to represent a collection of rules. A rule consists of conditions and resulting actions. Weitere Informationen finden Sie unter Using the PolicyActivity Activity. |
|
Creates multiple instances of a single child activity. Weitere Informationen finden Sie unter Using the ReplicatorActivity Activity. |
|
Provides a simple way to link multiple activities together for sequential execution. Weitere Informationen finden Sie unter Using the SequenceActivity Activity. |
|
Specifies a transition to a new state. Weitere Informationen finden Sie unter Using the SetStateActivity Activity. |
|
Represents a state in a state machine workflow. Weitere Informationen finden Sie unter Using the StateActivity Activity. |
|
Used in a StateActivity activity as a container for child activities that are executed when leaving the StateActivity activity. Weitere Informationen finden Sie unter Using the StateFinalizationActivity Activity. |
|
Used in a StateActivity activity as a container for child activities that are executed when entering the StateActivity activity. Weitere Informationen finden Sie unter Using the StateInitializationActivity Activity. |
|
Suspends the operation of your workflow to enable intervention in the event of some error condition that requires special attention. Weitere Informationen finden Sie unter Using the SuspendActivity Activity. |
|
Executes contained activities sequentially in a synchronized domain. Weitere Informationen finden Sie unter Using the SynchronizationScopeActivity Activity. |
|
Enables you to immediately end the operation of your workflow in the event of an error condition. Weitere Informationen finden Sie unter Using the TerminateActivity Activity. |
|
Enables you to capture business exceptions thrown as part of the process metadata for a workflow. Weitere Informationen finden Sie unter Using the ThrowActivity Activity. |
|
Provides a framework for transactions and exception handling. For more information, see Using the TransactionScopeActivity Activity. |
|
Enables you to model the occurrence of a Web service fault. Weitere Informationen finden Sie unter Using the WebServiceFaultActivity Activity. |
|
Receives data from a Web service. Weitere Informationen finden Sie unter Using the WebServiceInputActivity Activity. |
|
Responds to a Web service request made to a workflow. Weitere Informationen finden Sie unter Using the WebServiceOutputActivity Activity. |
|
Enables your workflow to loop until a condition is met. Weitere Informationen finden Sie unter Using the WhileActivity Activity. |
