XmlWriterSettings.OmitXmlDeclaration Property
Gets or sets a value indicating whether to write an XML declaration.
Assembly: System.Xml (in System.Xml.dll)
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.
The following example writes an XML fragment to a memory stream.
XmlWriterSettings settings = new XmlWriterSettings(); settings.OmitXmlDeclaration = true; 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 additonal processing on the stream.
