This tutorial illustrates how to write Report Definition Language (RDL) to a report definition file using the System.Xml.XmlTextWriter class. The writer provides a fast, forward-only way of generating XML, thus RDL, and helps you to build report definition documents that conform to the RDL specification. The System.Xml.XmlTextWriter writes to a stream rather than using an object model such as the XML DOM, and so gives better performance.
Typically, you use an System.Xml.XmlTextWriter if you need to write XML as raw data without the overhead of a DOM. The System.Xml.XmlTextWriter is an implementation of the System.Xml.XmlTextWriter class that provides the API which writes XML to a file stream. The XmlTextWriter class provides several methods that are useful for creating a report definition file. In particular, the following tutorial shows you how to construct a report definition file using the System.Xml.XmlTextWriter.WriteStartElement, System.Xml.XmlTextWriter.WriteAttributeString, System.Xml.XmlTextWriter.WriteElementString, and System.Xml.XmlTextWriter.WriteEndElement methods.
