using System.Xml;

public class Sample {

  public static void Main() {

     // Create an XmlWriter to write XML fragments.
     XmlWriterSettings settings = new XmlWriterSettings();
     settings.ConformanceLevel = ConformanceLevel.Fragment;
     settings.Indent = true;
     XmlWriter writer = XmlWriter.Create(Console.Out, settings);

     // Write an XML fragment.
     writer.WriteStartElement("book");
     writer.WriteElementString("title", "Pride And Prejudice");
     writer.WriteEndElement();
     writer.Flush();

     // Write another XML fragment.
     writer.WriteStartElement("cd");
     writer.WriteElementString("title", "Americana");
     writer.WriteEndElement();
     writer.Flush();

     // Close the writer.
     writer.Close();
  }
}

Imports System.IO
Imports System.Xml

Public Class Sample

  Public Shared Sub Main()

     ' Create an XmlWriter to write XML fragments.
     Dim settings As XmlWriterSettings = new XmlWriterSettings()
     settings.ConformanceLevel = ConformanceLevel.Fragment
     settings.Indent = true
     Dim writer As XmlWriter = XmlWriter.Create(Console.Out, settings)
    
     ' Write an XML fragment.
     writer.WriteStartElement("book")
     writer.WriteElementString("title", "Pride And Prejudice")
     writer.WriteEndElement()
     writer.Flush()

     ' Write another XML fragment.
     writer.WriteStartElement("cd")
     writer.WriteElementString("title", "Americana")
     writer.WriteEndElement()
     writer.Flush()  

     'Close the writer.
     writer.Close()

  End Sub
End Class

Keterangan

Ini dipanggil alih-alih Close ketika Anda ingin menulis lebih banyak ke aliran yang mendasar tanpa kehilangan apa yang masih ada di buffer.

Untuk versi asinkron dari metode ini, lihat FlushAsync.
