Beispiele

Im folgenden Beispiel wird eine Klasse mit dem Namen Group". Dies SoapTypeAttribute wird auf die Klasse angewendet, wobei der TypeName Wert auf "SoapGroupType" festgelegt ist. Dies SoapTypeAttribute wird auch außer Kraft gesetzt, indem sie in TypeName "Team" geändert wird. Beide Versionen werden serialisiert, was zu zwei Dateien führt: SoapType.xml und SoapType2.xml.

Hinweise

Die SoapTypeAttribute Klasse gehört zu einer Familie von Attributen, die steuert, wie das XmlSerializer Serialisieren oder Deserialisieren eines Objekts als codierte SOAP-XML-Code. Der resultierende XML-Code entspricht Abschnitt 5 des World Wide Web Consortium-Dokuments, Simple Object Access Protocol (SOAP) 1.1. Eine vollständige Liste ähnlicher Attribute finden Sie unter Attribute, die codierte SOAP-Serialisierung steuern.

Um ein Objekt als codierte SOAP-Nachricht serialisieren zu können, erstellen Sie die XmlSerializer Verwendung einer XmlTypeMapping mit der ImportTypeMapping Methode der SoapReflectionImporter Klasse erstellten.

Dies SoapTypeAttribute kann nur auf Klassendeklarationen angewendet werden.

Die IncludeInSchema Eigenschaft bestimmt, ob der resultierende XML-Elementtyp im XML-Schemadokument (XSD) für den generierten XML-Datenstrom enthalten ist. Um das Schema anzuzeigen, kompilieren Sie die Klasse in eine DLL-Datei. Übergeben Sie die resultierende Datei als Argument an das XML-Schemadefinitionstool (Xsd.exe). Das Tool generiert das XML-Schema für den XML-Datenstrom, der generiert wird, wenn die Klasse von einer Instanz der XmlSerializer Klasse serialisiert wird.

Durch das Festlegen eines anderen Namespaces wird Xsd.exe zum Schreiben einer anderen Schemadatei (XSD)-Datei für den XML-Datenstrom verursacht, der generiert wird, wenn die Klasse serialisiert wird.

Konstruktoren

SoapTypeAttribute()	Initialisiert eine neue Instanz der SoapTypeAttribute-Klasse.
SoapTypeAttribute(String)	Initialisiert eine neue Instanz der SoapTypeAttribute-Klasse und gibt den Namen des XML-Typs an.
SoapTypeAttribute(String, String)	Initialisiert eine neue Instanz der SoapTypeAttribute-Klasse und gibt den Namen und XML-Namespace des Typs an.

Eigenschaften

IncludeInSchema	Ruft einen Wert ab, der angibt, ob der Typ in SOAP-codierte XML-Schemadokumente aufgenommen werden soll, oder legt diesen fest.
Namespace	Ruft den Namespace des XML-Typs ab oder legt diesen fest.
TypeId	Ruft bei Implementierung in einer abgeleiteten Klasse einen eindeutigen Bezeichner für dieses Attribute ab. (Geerbt von Attribute)
TypeName	Ruft den Namen des XML-Typs ab oder legt diesen fest.

Methoden

Equals(Object)	Gibt einen Wert zurück, der angibt, ob diese Instanz gleich einem angegebenen Objekt ist. (Geerbt von Attribute)
GetHashCode()	Gibt den Hashcode für diese Instanz zurück. (Geerbt von Attribute)
GetType()	Ruft den Type der aktuellen Instanz ab. (Geerbt von Object)
IsDefaultAttribute()	Gibt beim Überschreiben in einer abgeleiteten Klasse an, ob der Wert der Instanz der Standardwert für die abgeleitete Klasse ist. (Geerbt von Attribute)
Match(Object)	Beim Überschreiben in einer abgeleiteten Klasse wird ein Wert zurückgegeben, der angibt, ob diese Instanz einem bestimmten Objekt entspricht. (Geerbt von Attribute)
MemberwiseClone()	Erstellt eine flache Kopie des aktuellen Object. (Geerbt von Object)
ToString()	Gibt eine Zeichenfolge zurück, die das aktuelle Objekt darstellt. (Geerbt von Object)

Explizite Schnittstellenimplementierungen

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)	Ordnet eine Reihe von Namen einer entsprechenden Reihe von Dispatchbezeichnern zu. (Geerbt von Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)	Ruft die Typinformationen für ein Objekt ab, mit deren Hilfe die Typinformationen für eine Schnittstelle abgerufen werden können. (Geerbt von Attribute)
_Attribute.GetTypeInfoCount(UInt32)	Ruft die Anzahl der Schnittstellen mit Typinformationen ab, die von einem Objekt bereitgestellt werden (0 oder 1). (Geerbt von Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)	Stellt den Zugriff auf von einem Objekt verfügbar gemachte Eigenschaften und Methoden bereit. (Geerbt von Attribute)
