LINQ to Twilio 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 Twilio Data Provider.

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

  4. Enter your data source connection information.

    Use the AccountSid and AuthToken connection properties to access data from your account. You obtain your live credentials on your Twilio account dashboard. Click Account -> Account Settings to obtain your test credentials.

    Below is a typical connection string:

    AccountSid=MyAccountSid;AuthToken=MyAuthToken;
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting TwilioEntities 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:

TwilioEntities context = new TwilioEntities(); var callsQuery = from calls in context.Calls select calls; foreach (var result in callsQuery) { Console.WriteLine("{0} {1} ", result.Sid, result.To); }

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