public:
 XmlTypeAttribute(System::String ^ typeName);

public XmlTypeAttribute (string typeName);

public XmlTypeAttribute (string? typeName);

new System.Xml.Serialization.XmlTypeAttribute : string -> System.Xml.Serialization.XmlTypeAttribute

Parameter

typeName: String

Der Name des XML-Typs, der vom XmlSerializer beim Serialisieren einer Klasseninstanz generiert bzw. beim Deserialisieren der Klasseninstanz erkannt wird.

Hinweise

Wenden Sie auf XmlTypeAttribute eine Klasse an, um den Namespace des XML-Typs, den XML-Typnamen und die Angabe, ob der Typ in das XML-Schemadokument eingeschlossen werden soll. Um die Ergebnisse des Festlegens der Eigenschaften der XmlTypeAttribute -Klasse anzuzeigen, kompilieren Sie Ihre Anwendung als ausführbare Datei oder DLL, und übergeben Sie die resultierende Datei an das XML-Schemadefinitionstool (Xsd.exe). Das Tool schreibt das Schema, einschließlich der Typdefinition.
