Hinweise

Hinweis

Ab dem .NET Framework 2.0 wird empfohlen, Instanzen mithilfe der XmlWriter.Create -Methode und der XmlWriterSettings -Klasse zu erstellenXmlWriter, um die neuen Funktionen zu nutzen.

Der Einzug wird für die folgenden Knotentypen ausgeführt: DocumentType, , ElementComment, ProcessingInstructionund CDATASection. Alle anderen Knotentypen sind nicht betroffen. Die XmlTextWriter interne DTD-Teilmenge wird nicht eingerückt. Sie können jedoch wie folgt vorgehen, um Formatierungen auf die interne DTD-Teilmenge anzuwenden.

String name = "Employees";
String pubid = null;
String sysid = null;
String subset =
@"
    <!ELEMENT Employees (Employee)+>
    <!ELEMENT Employee EMPTY>
    <!ATTLIST Employee firstname CDATA #REQUIRED>
    <!ENTITY Company 'Microsoft'>]>
";
XmlTextWriter tw = new XmlTextWriter(Console.Out);
tw.WriteDocType(name, pubid, sysid, subset);
