LINQ to RSS Feeds


LINQ offers versatile querying capabilities within the .NET Framework (v3.0+), offering a straightforward method for programmatic data access through CData ADO.NET Data Providers. In this article, we demonstrate the use of LINQ to retrieve information from the RSS Data Provider.

This article illustrates using LINQ to access tables within the RSS via the CData ADO.NET Data Provider for RSS. To achieve this, we will use LINQ to Entity Framework, which facilitates the generation of connections and can be seamlessly employed with any CData ADO.NET Data Providers to access data through LINQ.

See the help documentation for a guide to setting up an EF 6 project to use the provider.

  1. In a new project in Visual Studio, right-click on the project and choose to add a new item. Add an ADO.NET Entity Data Model.
  2. Choose EF Designer from Database and click Next.
  3. Add a new Data Connection, and change your data source type to "CData RSS Data Source".

  4. Enter your data source connection information.

    You can connect to RSS and Atom feeds, as well as feeds with custom extensions. To connect to a feed, set the URL property. You can also access secure feeds. A variety of authentication mechanisms are supported. See the help documentation for details.

    Below is a typical connection string:

    URI=http://broadcastCorp/rss/;
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting RSSEntities as our entity connection in App.Config.
  6. Enter a model name and select any tables or views you would like to include in the model.

Using the entity you created, you can now perform select commands. For example:

RSSEntities context = new RSSEntities(); var latest newsQuery = from latest news in context.Latest News select latest news; foreach (var result in latest newsQuery) { Console.WriteLine("{0} {1} ", result.GUID, result.Author); }

See "LINQ and Entity Framework" chapter in the help documentation for example queries of the supported LINQ.
