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.
System.Workflow.Runtime.Hosting.WorkflowRuntimeService
System.Workflow.Activities.ExternalDataExchangeService
Namespace: System.Workflow.Activities
Assembly: System.Workflow.Activities (in System.Workflow.Activities.dll)
The ExternalDataExchangeService type exposes the following members.
| Name | Description | |
|---|---|---|
 | ExternalDataExchangeService() | Initializes a new instance of the ExternalDataExchangeService class. |
| ExternalDataExchangeService(ExternalDataExchangeServiceSection) | Initializes a new instance of the ExternalDataExchangeService class. |
| ExternalDataExchangeService(NameValueCollection) | Initializes a new instance of the ExternalDataExchangeService class. |
| ExternalDataExchangeService(String) | Initializes a new instance of the ExternalDataExchangeService class. |
| Name | Description | |
|---|---|---|
| Runtime | Gets the WorkflowRuntime for this service. (Inherited from WorkflowRuntimeService.) |
| State | Gets the state of the WorkflowRuntimeService. (Inherited from WorkflowRuntimeService.) |
| Name | Description | |
|---|---|---|
| AddService | Adds the specified service to the ExternalDataExchangeService. |
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetService | Gets the service implementation of the specified interface type, if the service is available. |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| OnStarted | When 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.) |
| OnStopped | When 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.) |
| RaiseServicesExceptionNotHandledEvent | Raises the WorkflowRuntime.ServicesExceptionNotHandled event. (Inherited from WorkflowRuntimeService.) |
| RemoveService | Removes the specified service from the ExternalDataExchangeService. |
| Start | Adds local services if a configuration section was specified during construction of the object. (Overrides WorkflowRuntimeService.Start().) |
| Stop | When overridden in a derived class, stops the service and changes the State to Stopping. (Inherited from WorkflowRuntimeService.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |

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.
