settings.ConformanceLevel = ConformanceLevel.Fragment;
settings.CloseOutput = false;
// Create the XmlWriter object and write some content.
MemoryStream strm = new MemoryStream();
XmlWriter writer = XmlWriter.Create(strm, settings);
writer.WriteElementString("orderID", "1-456-ab");
writer.WriteElementString("orderID", "2-36-00a");
writer.Flush();
writer.Close();
// Do additional processing on the stream.
Dim settings As XmlWriterSettings = New XmlWriterSettings()
settings.OmitXmlDeclaration = true
settings.ConformanceLevel = ConformanceLevel.Fragment
settings.CloseOutput = false
' Create the XmlWriter object and write some content.
Dim strm as MemoryStream = new MemoryStream()
Dim writer As XmlWriter = XmlWriter.Create(strm, settings)
writer.WriteElementString("orderID", "1-456-ab")
writer.WriteElementString("orderID", "2-36-00a")
writer.Flush()
writer.Close()

Remarks
This property only applies to XmlWriter instances that output text content; otherwise, this setting is ignored.
If OmitXmlDeclaration is set to false, The XML declaration is written automatically
The XML declaration is always written if ConformanceLevel is set to Document, even if OmitXmlDeclaration is set to true.
The XML declaration is never written if ConformanceLevel is set to Fragment. You can call WriteProcessingInstruction to explicitly write out an XML declaration.
