My article entitled Sample uses of LINQ, DLINQ and XLINQ is now available in English. In this article, we will see how to put LINQ, DLINQ and XLINQ in action. The goal is just to show how to use these technologies, and not to provide a target architecture or demonstrate optimal uses. The goal is not...

Steve has published on his blog a sample from the book we are working on together. This example shows how LINQ to XML makes it easy to convert a CSV file into an XML document. Going from CSV to XML doesn't require something more complicated than this: XElement xml = new XElement("books"...

It's not something built-in. There is no Random query operator provided by Microsoft. In addition, it can't be done simply...

As an example that will be included in the Linq in Action book , I've created an example that shows how Linq can be extended to query anything. This example introduces Linq to Amazon , which allows querying Amazon for books using Linq! It uses Linq's extensibility to allow for language-integrated queries...

A frequent question we get about our LINQ book is whether it's been written for C# developers only. If you think so, you're making a mistake. We cover both C# and VB.NET in the book. This is one big difference with competing books. Even if not all code samples are in both languages all the time in the...
