ExternalDataEventArgs Class
Note: This API is now obsolete.
Represents the data sent when an event is raised using the HandleExternalEventActivity activity.
Assembly: System.Workflow.Activities (in System.Workflow.Activities.dll)
The ExternalDataEventArgs type exposes the following members.
| Name | Description | |
|---|---|---|
 | ExternalDataEventArgs() | Initializes a new instance of the ExternalDataEventArgs class. |
| ExternalDataEventArgs(Guid) | Initializes a new instance of the ExternalDataEventArgs class using the instance identifier of the workflow. |
| ExternalDataEventArgs(Guid, IPendingWork, Object) | Initializes a new instance of the ExternalDataEventArgs class. |
| ExternalDataEventArgs(Guid, IPendingWork, Object, Boolean) | Initializes a new instance of the ExternalDataEventArgs class. |
| Name | Description | |
|---|---|---|
| Identity | Gets or sets the identity of the user that raised the event. |
| InstanceId | Gets or sets the workflow instance identifier for the workflow instance that contains the HandleExternalEventActivity that is expected to handle the event. |
| WaitForIdle | Gets or sets a value that indicates whether the event should be raised immediately, or if the workflow should go idle before raising the event. |
| WorkHandler | Gets or sets the IPendingWork to allow the external code, raising the event, to participate in the batch. |
| WorkItem | Gets or sets the object that contains the external code that raises the event. |
| Name | Description | |
|---|---|---|
| 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.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |

A local communication interface marked with ExternalDataExchangeAttribute must declare a type that derives from ExternalDataEventArgs in the interface definition for the corresponding event to be handled in a workflow with a HandleExternalEventActivity activity.
An event class that inherits from ExternalDataEventArgs must implement a constructor that uses the :base(instanceId) constructor. In addition, the new event class must be marked as Serializable as shown in the following code.
[Serializable] public class TaskEventArgs : ExternalDataEventArgs { private string orderName; public TaskEventArgs(Guid instanceId, string id) :base(instanceId) { orderName = id; } public string Id { get { return orderName; } set { orderName = value; } } }
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
