    // Create an AnnotationStore using the file stream.
    _annotStore = new XmlStreamStore(_annotStream);

    // Enable the AnnotationService using the new store.
    _annotService.Enable(_annotStore);
}// end:StartAnnotations()

Opmerkingen

De AnnotationService kan worden gebruikt met de volgende besturingselementen voor documentweergave:

AnnotationService(FlowDocumentReader)

Initialiseert een nieuw exemplaar van de AnnotationService klasse voor gebruik met een opgegeven besturingselement FlowDocumentReader .

public:
 AnnotationService(System::Windows::Controls::FlowDocumentReader ^ viewer);
public AnnotationService(System.Windows.Controls.FlowDocumentReader viewer);
new System.Windows.Annotations.AnnotationService : System.Windows.Controls.FlowDocumentReader -> System.Windows.Annotations.AnnotationService
Public Sub New (viewer As FlowDocumentReader)

Parameters

viewer
FlowDocumentReader

Het besturingselement voor het lezen van documenten dat is gekoppeld aan de AnnotationService.
