Examples

The following example demonstrates an implementation of the RestoreFromDefaultSerializedForm method. This example is from the Custom Persistence Service sample, from the FilePersistenceService.cs file. For more information, see Custom Persistence Service Sample.

// Load the completed activity state.
protected override Activity LoadCompletedContextActivity(Guid activityId, Activity outerActivity)
{
    Console.WriteLine("Loading completed activity context: {0}", activityId);
    byte[] workflowBytes = DeserializeFromFile(activityId);
    Activity deserializedActivities = WorkflowPersistenceService.RestoreFromDefaultSerializedForm(workflowBytes, outerActivity);
    return deserializedActivities;
}

' Load completed activity state.
Protected Overrides Function LoadCompletedContextActivity(ByVal scopeId As System.Guid, ByVal outerActivity As System.Workflow.ComponentModel.Activity) As System.Workflow.ComponentModel.Activity
    Console.WriteLine("Loading completed activity context: 0}", scopeId)
    Dim workflowBytes As Byte() = DeserializeFromFile(scopeId)
    Dim deserializedActivities As Activity = WorkflowPersistenceService.RestoreFromDefaultSerializedForm(workflowBytes, outerActivity)
    Return deserializedActivities
End Function
