The sample is a short introduction to System.Xml.Linq building on the user's familiarity with the XML DOM API. The goal is to illustrate how to construct a predefined XML document by using LINQ to XML. Two different approaches are showcased. First, the document is assembled by using XML DOM-like API (see CreateDocumentVerbose()). Note the various options to add nodes to the document. The second approach, known as functional construction, is a more concise style that achieves the same result (see CreateDocumentConcise()). The sample also shows a method of traversing the document (see DumpNode()). Note the familiar properties exposed on the various node types.


Many LINQ samples require XML files and/or the version of the Northwind sample database that is located in the Data sample. If you install the Data Sample in the same parent folder as the other LINQ samples, the path for the XML files and database file will be resolved automatically. Many sample files also require the Object Dumper Sample project.
