       settings.Indent = true;
       settings.IndentChars = ("\t");
       settings.OmitXmlDeclaration = true;

       // Create the XmlWriter object and write some content.
       writer = XmlWriter.Create("data.xml", settings);
       writer.WriteStartElement("book");
       writer.WriteElementString("item", "tesing");
       writer.WriteEndElement();
    
       writer.Flush();

        if (writer != null)
          writer.Close();
     }

Public Class Sample 

  Public Shared Sub Main() 
  
    Dim writer As XmlWriter = Nothing

    Try 

       ' Create an XmlWriterSettings object with the correct options. 
       Dim settings As XmlWriterSettings = New XmlWriterSettings()
       settings.Indent = true
       settings.IndentChars = (ControlChars.Tab)
       settings.OmitXmlDeclaration = true

       ' Create the XmlWriter object and write some content.
