Introduction to LINQ to XML Sample

The Introduction to LINQ to XML sample demonstrates key concepts about the technology.

To get samples and instructions for installing them

  • Do one or more of the following:

    • On the Help menu, click Samples.

      The Readme displays information about samples.

    • Visit the Visual Studio 2008 Samples Web site. The most recent versions of samples are available there.

    • Locate samples on the computer on which Visual Studio is installed. By default, samples and a Readme file are installed in drive:\Program Files\Microsoft Visual Studio 9.0\Samples\lcid. For Express editions of Visual Studio, all samples are located online.

For more information, see Visual Studio Samples.

Demonstrates

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.

Note

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.
