LINQ to Google Calendar Data


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 Google Calendar Data Provider.

This article illustrates using LINQ to access tables within the Google Calendar via the CData ADO.NET Data Provider for Google Calendar. 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 Google Calendar Data Source".

  4. Enter your data source connection information.

    You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting GoogleCalendarEntities 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 , update, delete, and insert commands. For example:

GoogleCalendarEntities context = new GoogleCalendarEntities(); var vacationcalendarQuery = from vacationcalendar in context.VacationCalendar select vacationcalendar; foreach (var result in vacationcalendarQuery) { Console.WriteLine("{0} {1} ", result.Id, result.Summary); }

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