ExternalDataExchangeService Class

Note: This API is now obsolete.

Represents a service that must be added to the workflow run-time 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.


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

[ObsoleteAttribute("The System.Workflow.* types are deprecated.  Instead, please use the new types from System.Activities.*")]
public class ExternalDataExchangeService : WorkflowRuntimeService

The ExternalDataExchangeService type exposes the following members.

Public methodExternalDataExchangeService()Initializes a new instance of the ExternalDataExchangeService class.
Public methodExternalDataExchangeService(ExternalDataExchangeServiceSection)Initializes a new instance of the ExternalDataExchangeService class.
Public methodExternalDataExchangeService(NameValueCollection)Initializes a new instance of the ExternalDataExchangeService class.
Public methodExternalDataExchangeService(String)Initializes a new instance of the ExternalDataExchangeService class.

Protected propertyRuntimeGets the WorkflowRuntime for this service. (Inherited from WorkflowRuntimeService.)
Protected propertyStateGets the state of the WorkflowRuntimeService. (Inherited from WorkflowRuntimeService.)

Public methodAddServiceAdds the specified service to the ExternalDataExchangeService.
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetServiceGets the service implementation of the specified interface type, if the service is available.
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodOnStartedWhen overridden in a derived class, represents the method that will be called when the workflow runtime engine raises the WorkflowRuntime.Started event. (Inherited from WorkflowRuntimeService.)
Protected methodOnStoppedWhen overridden in a derived class, represents the method that will be called when the workflow runtime engine raises the WorkflowRuntime.Stopped event. (Inherited from WorkflowRuntimeService.)
Protected methodRaiseServicesExceptionNotHandledEventRaises the WorkflowRuntime.ServicesExceptionNotHandled event. (Inherited from WorkflowRuntimeService.)
Public methodRemoveServiceRemoves the specified service from the ExternalDataExchangeService.
Protected methodStartAdds local services if a configuration section was specified during construction of the object. (Overrides WorkflowRuntimeService.Start().)
Protected methodStopWhen overridden in a derived class, stops the service and changes the State to Stopping. (Inherited from WorkflowRuntimeService.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)


This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

A local service implementation is a class that implements an interface that is marked with ExternalDataExchangeAttribute. Local services added in this way are used by CallExternalMethodActivity and HandleExternalEventActivity.
