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 Progettazione flussi di lavoro di Windows, 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 Progettazione flussi di lavoro. 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. Per ulteriori informazioni, vedere Using the CallExternalMethodActivity Activity. |
|
Used to contain cleanup logic for a composite activity canceled before all the composite activity's children are finished executing. Per ulteriori informazioni, vedere Using the CancellationHandlerActivity Activity. |
|
Enables you to add Visual Basic or C# code to your workflow. Per ulteriori informazioni, vedere Using the CodeActivity Activity. |
|
A compensatable version of SequenceActivity. Per ulteriori informazioni, vedere Using the CompensatableSequenceActivity Activity. |
|
A compensatable version of TransactionScopeActivity. Per ulteriori informazioni, vedere 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. Per ulteriori informazioni, vedere Using the CompensateActivity Activity. |
|
A wrapper for one or more activities that perform compensation for a completed TransactionScopeActivity activity Per ulteriori informazioni, vedere 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. Per ulteriori informazioni, vedere Using the ConditionedActivityGroup Activity. |
|
Enables you to build delays in your workflow that are based on a time-out interval. Per ulteriori informazioni, vedere Using the DelayActivity Activity. |
|
Wraps one or more activities that are executed when a specified event occurs. Per ulteriori informazioni, vedere Using the EventDrivenActivity Activity. |
|
Provides a framework for associating events with an activity. Per ulteriori informazioni, vedere Using the EventHandlersActivity Activity. |
|
Executes its main child activity concurrently with an EventHandlersActivity. Per ulteriori informazioni, vedere Using the EventHandlingScopeActivity Activity. |
|
Used to handle an exception of a type that you specify. Per ulteriori informazioni, vedere Using the FaultHandlerActivity Activity. |
|
Represents a composite activity that has an ordered list of child activities of type FaultHandlerActivity. Per ulteriori informazioni, vedere Using the FaultHandlersActivity Activity. |
|
Used in conjunction with the CallExternalMethodActivity activity for input and output communications with a local service. Per ulteriori informazioni, vedere Using the HandleExternalEventActivity Activity. |
|
Tests a condition on each branch and performs activities on the first branch for which the condition equals true. Per ulteriori informazioni, vedere Using the IfElseActivity Activity. |
|
Represents a branch of an IfElseActivity. Per ulteriori informazioni, vedere Using the IfElseBranchActivity Activity. |
|
Enables your workflow to invoke a Web service. Per ulteriori informazioni, vedere Using the InvokeWebServiceActivity Activity. |
|
Enables your workflow to invoke another workflow. Per ulteriori informazioni, vedere Using the InvokeWorkflowActivity Activity. |
|
A composite activity that contains only EventDrivenActivity child activities. Per ulteriori informazioni, vedere Using the ListenActivity Activity. |
|
Provides a way to schedule two or more child SequenceActivity activity branches for processing at the same time. Per ulteriori informazioni, vedere Using the ParallelActivity Activity. |
|
Use to represent a collection of rules. A rule consists of conditions and resulting actions. Per ulteriori informazioni, vedere Using the PolicyActivity Activity. |
|
Creates multiple instances of a single child activity. Per ulteriori informazioni, vedere Using the ReplicatorActivity Activity. |
|
Provides a simple way to link multiple activities together for sequential execution. Per ulteriori informazioni, vedere Using the SequenceActivity Activity. |
|
Specifies a transition to a new state. Per ulteriori informazioni, vedere Using the SetStateActivity Activity. |
|
Represents a state in a state machine workflow. Per ulteriori informazioni, vedere Using the StateActivity Activity. |
|
Used in a StateActivity activity as a container for child activities that are executed when leaving the StateActivity activity. Per ulteriori informazioni, vedere Using the StateFinalizationActivity Activity. |
|
Used in a StateActivity activity as a container for child activities that are executed when entering the StateActivity activity. Per ulteriori informazioni, vedere Using the StateInitializationActivity Activity. |
|
Suspends the operation of your workflow to enable intervention in the event of some error condition that requires special attention. Per ulteriori informazioni, vedere Using the SuspendActivity Activity. |
|
Executes contained activities sequentially in a synchronized domain. Per ulteriori informazioni, vedere Using the SynchronizationScopeActivity Activity. |
|
Enables you to immediately end the operation of your workflow in the event of an error condition. Per ulteriori informazioni, vedere Using the TerminateActivity Activity. |
|
Enables you to capture business exceptions thrown as part of the process metadata for a workflow. Per ulteriori informazioni, vedere 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. Per ulteriori informazioni, vedere Using the WebServiceFaultActivity Activity. |
|
Receives data from a Web service. Per ulteriori informazioni, vedere Using the WebServiceInputActivity Activity. |
|
Responds to a Web service request made to a workflow. Per ulteriori informazioni, vedere Using the WebServiceOutputActivity Activity. |
|
Enables your workflow to loop until a condition is met. Per ulteriori informazioni, vedere Using the WhileActivity Activity. |
