To run this sample

  • Press F5.

The sample is a short introduction to System.Xml.Linq. It takes your familiarity with the XML DOM API as a starting point. The goal is to illustrate how to construct a predefined XML document by using LINQ to XML. Two different approaches are demonstrated.

  • First, the document is assembled by using an approach similar to XML DOM. (See method CreateDocumentVerbose.) Notice the various ways in which different nodes are added to the document in CreateDocumentVerbose.

  • The second approach, known as functional construction, is a more concise style that achieves the same result. (See method CreateDocumentConcise.)

The sample also provides a method for traversing the document (method DumpNode).

Note the familiar properties exposed on the various node types.
