- Inheritance
- Attributes
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; }
}
}
Note
This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.
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.
