XmlSchemaAll-Klasse
Stellt das W3C-all-Element (World Wide Web Consortium) dar (Compositor).
Namespace: System.Xml.Schema
Assembly: System.Xml (in system.xml.dll)
Syntax
'Declaration
Public Class XmlSchemaAll
Inherits XmlSchemaGroupBase
'Usage
Dim instance As XmlSchemaAll
public class XmlSchemaAll : XmlSchemaGroupBase
public ref class XmlSchemaAll : public XmlSchemaGroupBase
public class XmlSchemaAll extends XmlSchemaGroupBase
public class XmlSchemaAll extends XmlSchemaGroupBase
Hinweise
Die XmlSchemaAll-Klasse erlaubt oder verhindert das Auftreten der Elemente in der Gruppe in beliebiger Reihenfolge in dem Element, in dem diese enthalten sind.
