Observação

A partir do .NET Framework 2.0, recomendamos que você crie XmlWriter instâncias usando o XmlWriter.Create método e a XmlWriterSettings classe para aproveitar a nova funcionalidade.

O recuo é executado nos seguintes tipos de nó: DocumentType, , Element, Commente ProcessingInstruction``CDATASection. Todos os outros tipos de nó não são afetados. O XmlTextWriter subconjunto DTD interno não recuou. No entanto, você pode fazer o seguinte para aplicar a formatação ao subconjunto DTD interno.

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);
