     writer = new XmlTextWriter (Console.Out);

     //Use indentation for readability.
     writer.Formatting = Formatting.Indented;
     writer.Indentation = 4;

     //Write an element (this one is the root).
     writer.WriteStartElement("book");

     //Write the title element.
     writer.WriteStartElement("title");
     writer.WriteString("Pride And Prejudice");
     writer.WriteEndElement();

        writer = New XmlTextWriter(Console.Out)
        
        'Use indentation for readability.
        writer.Formatting = Formatting.Indented
        writer.Indentation = 4
        
        'Write an element (this one is the root).

注解

注释

建议使用XmlWriter方法和XmlWriter.Create类创建XmlWriterSettings实例，以利用新功能。

缩进在以下节点类型上执行：DocumentType、、ElementComment、ProcessingInstruction和CDATASection。 所有其他节点类型都不会受到影响。 不会 XmlTextWriter 缩进内部 DTD 子集。 但是，可以执行以下操作，将格式应用于内部 DTD 子集。

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);
