Hinweise

Ein Designer kann IDesignerSerializationManager für den Zugriff auf Dienste nützlich sein, um Entwurfszeit-Serialisierungsprozesse zu verwalten. Beispielsweise kann eine Klasse, die den Designer-Serialisierungs-Manager implementiert, verwenden, um Objekte zu erstellen, Typen nachzuschlagen, Objekte zu identifizieren und die Serialisierung bestimmter Typen anzupassen.

Eigenschaften

Context	Ruft einen stapelbasierten, benutzerdefinierten Speicherbereich ab, der die Kommunikation zwischen Serialisierungsprogrammen erleichtert.
Properties	Gibt benutzerdefinierte Eigenschaften an, die mit verfügbaren Serialisierungsprogrammen serialisiert werden können.

Methoden

AddSerializationProvider(IDesignerSerializationProvider)	Fügt dem Serialisierungs-Manager den angegebenen Serialisierungsprovider hinzu.
CreateInstance(Type, ICollection, String, Boolean)	Erstellt eine Instanz des angegebenen Typs und fügt sie einer Auflistung benannter Instanzen hinzu.
GetInstance(String)	Ruft eine Instanz eines erstellten Objekts mit dem angegebenen Namen ab oder null, wenn dieses Objekt nicht vorhanden ist.
GetName(Object)	Ruft den Namen des angegebenen Objekts ab oder null, wenn dem Objekt kein Name zugewiesen ist.
GetSerializer(Type, Type)	Ruft ein Serialisierungsprogramm vom angeforderten Typ für den angegebenen Objekttyp ab.
GetService(Type)	Ruft das Dienstobjekt des angegebenen Typs ab. (Geerbt von IServiceProvider)
GetType(String)	Ruft einen Typ mit dem angegebenen Namen ab.
RemoveSerializationProvider(IDesignerSerializationProvider)	Entfernt einen benutzerdefinierten Serialisierungsprovider aus dem Serialisierungs-Manager.
ReportError(Object)	Meldet einen Fehler bei der Serialisierung.
SetName(Object, String)	Legt den Namen des angegebenen vorhandenen Objekts fest.

Ereignisse

ResolveName	Tritt ein, wenn GetName(Object) den angegebenen Namen in der Namenstabelle des Serialisierungs-Managers nicht finden kann.
SerializationComplete	Tritt ein, wenn die Serialisierung abgeschlossen ist.
