System.Workflow.Activities, espace de noms

Defines activities that can be added to workflows to create and run an executable representation of a work process.

 ClasseDescription
Classe publiqueActiveDirectoryRoleRepresents an Active Directory role in a Windows Workflow Foundation hosting environment. This class cannot be inherited.
Classe publiqueActiveDirectoryRoleFactoryA factory class for creating ActiveDirectoryRole objects from Windows NT aliases, e-mail addresses, and security identifiers (SIDs).
Classe publiqueCallExternalMethodActivityDefines a workflow communication activity that is used to call a method on a local service. This activity is used to send data from the workflow to the host through the local service.
Classe publiqueCallExternalMethodActivityValidatorVerifies that the CallExternalMethodActivity class is configured correctly.
Classe publiqueCodeActivityRuns the code-beside method associated with an activity. This class cannot be inherited.
Classe publiqueCodeConditionDefines a condition that guards/drives the execution of a certain activity within a workflow definition. It has an event of type ConditionalEventArgs to return the result of the condition.
Classe publiqueCompensatableSequenceActivityDefines a compensatable version of the SequenceActivity activity. This class cannot be inherited.
Classe publiqueConditionalEventArgsReturns result information for the CodeCondition class. This class cannot be inherited.
Classe publiqueConditionedActivityGroupProvides the definition of a constraint-based execution context for a set of child activities.
Classe publiqueCorrelationAliasAttributeOverrides the correlation parameter value when the correlation value must be obtained from a parameter other than that indicated by the CorrelationParameterAttribute. This class cannot be inherited.
Classe publiqueCorrelationInitializerAttributeIndicates the method or event on an ExternalDataExchange interface that initializes the correlation value. This class cannot be inherited.
Classe publiqueCorrelationParameterAttributeIndicates the name of the parameter used for correlation in the methods and events defined on an ExternalDataExchange interface. This class cannot be inherited.
Classe publiqueDelayActivityProvides the logic to establish a timer and to wait, asynchronously, for timer's expiration. This class cannot be inherited.
Classe publiqueEventDeliveryFailedExceptionThe exception that is thrown when an event that is raised from the host cannot be delivered to the workflow instance. Typically the event is raised from an ExternalDataExchangeService on a workflow instance. This class cannot be inherited.
Classe publiqueEventDrivenActivityWraps an Activity whose execution is initialized by an event. This class cannot be inherited. It is a CompositeActivity that is used to handle an event; typically it can be raised from the host or by the run time in reponse to a delay timer expiring. EventDrivenActivity is inherited from SequenceActivity; therefore it is a sequence that has the additional restriction that the first activity should be an IEventActivity.
Classe publiqueEventHandlersActivityA composite activity that contains a collection of event handlers. It is typically used where a collection of events must be handled. Each event is handled by one EventDrivenActivity, which is part of EventHandlersActivity.
Classe publiqueEventHandlingScopeActivityEnables event handling with the execution of the child activities. This class cannot be inherited.
Classe publiqueEventQueueNameRepresents the name of a queue associated with an event on a WorkflowInstance. This class cannot be inherited.
Classe publiqueExternalDataEventArgsRepresents the data sent along when an event is raised using the HandleExternalEventActivity.
Classe publiqueExternalDataExchangeAttributeMarks an interface as a local service interface. This class cannot be inherited.
Classe publiqueExternalDataExchangeServiceRepresents a service that must be added to the workflow runtime engine for local services communications to be enabled. Local service implementations are required to be added to the ExternalDataExchangeService for these services to be properly initialized and registered.
Classe publiqueExternalDataExchangeServiceSectionRepresents a configuration section that allows you to specify, in a configuration file, a set of services to be added to an instance of ExternalDataExchangeService.
Classe publiqueHandleExternalEventActivityDefines a workflow communication activity that is used to handle an event that is raised by a local service.
Classe publiqueHandleExternalEventActivityValidatorVerifies that the HandleExternalEventActivity class is configured correctly.
Classe publiqueIfElseActivityConditionally runs one of two or more activities of type IfElseBranchActivity. This class cannot be inherited.
Classe publiqueIfElseBranchActivityRepresents a branch of an IfElseActivity. This class cannot be inherited.
Classe publiqueInvokeWebServiceActivityInvokes a Web service through a proxy class, passing and receiving parameters as specified. This class cannot be inherited.
Classe publiqueInvokeWebServiceEventArgsContains event data used to invoke a Web service. This class cannot be inherited.
Classe publiqueInvokeWorkflowActivityAsynchronously runs one workflow from another. This class cannot be inherited.
Classe publiqueListenActivityMakes the workflow wait for any one of several possible events before the activity proceeds. This class cannot be inherited.
Classe publiqueMessageEventSubscriptionCreates a message event subscription to route messages to the appropriate workflow instance.
Classe publiqueParallelActivityRuns a set of child activities at the same time. This class cannot be inherited.
Classe publiquePolicyActivityRepresents a collection of Rule class instances to be run as part of a workflow's execution as a single step/activity.
Classe publiqueReplicatorActivityRuns multiple instances of a child activity.
Classe publiqueReplicatorChildEventArgsContains event arguments for the ReplicatorActivity activity handlers called at initialization of child Activity instances in addition to when the child Activity instances are finished.
Classe publiqueSequenceActivityRuns a set of child activities according to a single defined ordering.
Classe publiqueSequentialWorkflowActivityRepresents a workflow that executes activities sequentially.
Classe publiqueSetStateActivityProvides the transition to a StateActivity in a state machine workflow. This class cannot be inherited.
Classe publiqueSetStateEventArgsRepresents a class that is used as an argument to set the state of a StateMachineWorkflowActivity.
Classe publiqueStateActivityRepresents a state in a StateMachineWorkflowActivity.
Classe publiqueStateActivityValidatorRepresents a class that verifies whether a StateActivity class is configured correctly.
Classe publiqueStateFinalizationActivityRepresents an activity that executes contained activities before transitioning to another state in a state machine workflow. This class cannot be inherited.
Classe publiqueStateInitializationActivityActs as a container to a group of activities that will be executed when the StateActivity starts running. This class cannot be inherited.
Classe publiqueStateMachineWorkflowActivityServes as the root container for state machine workflows. Contains event-driven activities and states.
Classe publiqueStateMachineWorkflowInstanceRepresents a class that manages the current instance of a StateMachineWorkflowActivity. This class cannot be inherited.
Classe publiqueWebServiceFaultActivityEnables sending a fault to the Web service client from the workflow. This class cannot be inherited.
Classe publiqueWebServiceInputActivityEnables receiving data from a Web service in a workflow. This class cannot be inherited.
Classe publiqueWebServiceOutputActivityEnables sending data to a Web service from within a workflow. This class cannot be inherited.
Classe publiqueWebWorkflowRoleRepresents a Workflow role that is backed by a RoleProvider.
Classe publiqueWhileActivityRuns a child activity iteratively as long as a certain condition is true.
Classe publiqueWorkflowAuthorizationExceptionThe exception that is thrown when role validation fails due to a specified identity that is not contained in the WorkflowRoleCollection.
Classe publiqueWorkflowRoleThe abstract base class from which workflow roles are derived.
Classe publiqueWorkflowRoleCollectionRepresents a collection of WorkflowRole objects. This class cannot be inherited.
Classe publiqueWorkflowSubscriptionServiceProvides methods for a subscription service to manage subscriptions for a workflow runtime.
Classe publiqueWorkflowWebServiceRepresents the base class for all workflow Web services.

 InterfaceDescription
Interface publiqueIEventActivityProvides methods and properties that event driven activities must derive from, to be able to subscribe to events.

 ÉnumérationDescription
Énumération publiqueExecutionTypeSpecifies the execution mode for activities.
