This article demonstrates how to use LINQ to access Google Calendar tables through the
CData ADO.NET Data Provider for Google Calendar.
To do this you will LINQ to Entity Framework, which is used to generate the connection and
can be used with any CData ADO.NET Data Providers to access
data via LINQ.
See the help documentation for a guide to setting up an EF 6 project to use the provider.
- 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.
- Choose EF Designer from Database and click Next.
- Add a new Data Connection, and change your data source type to "CData Google Calendar Data Source".
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.
- 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.
- 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.
