#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   
   //Create a writer to write XML to the console.
   XmlTextWriter^ writer = nullptr;
   writer = gcnew 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();
   
   //Write the close tag for the root element.
   writer->WriteEndElement();
   
   //Write the XML to file and close the writer.
   writer->Close();
}

using System;
using System.IO;
using System.Xml;

public class Sample
{

  public static void Main()
  {
     //Create a writer to write XML to the console.
     XmlTextWriter writer = null;
     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();

     //Write the close tag for the root element.
     writer.WriteEndElement();

     //Write the XML to file and close the writer.
     writer.Close();
  }
}

Public Class Sample
    
    Public Shared Sub Main()
        'Create a writer to write XML to the console.
        Dim writer As XmlTextWriter = Nothing
        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()
        
        'Write the close tag for the root element.
        writer.WriteEndElement()
        
        'Write the XML to file and close the writer.
        writer.Close()
    End Sub
End Class

備註

注意

從 .NET Framework 2.0 開始，建議您使用 XmlWriter.Create 方法和 XmlWriterSettings 類別來建立 XmlWriter 實例，以利用新功能。

縮排是在下列節點類型上執行： DocumentType 、 Element 、、 Comment 、 ProcessingInstruction 和 CDATASection 。 所有其他節點類型都不會受到影響。 XmlTextWriter不會縮排內部 DTD 子集。 不過，您可以執行下列動作，將格式設定套用至內部 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);
