LINQ to Streak 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 Streak Data Provider.

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

  4. Enter your data source connection information.

    Use the following steps to generate a new API key for authenticating to Streak.

    1. Navigate to Gmail
    2. Click on the Streak dropdown to the right of the search bar
    3. Select the Integrations button. This will open a window where you can view existing integrations and create new API keys.
    4. Under the Streak API section of integrations, click the button to Create New Key.

    Below is a typical connection string:

    ApiKey=8c84j9b4j54762ce809ej6a782d776j3;
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting StreakEntities 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:

StreakEntities context = new StreakEntities(); var usersQuery = from users in context.Users select users; foreach (var result in usersQuery) { Console.WriteLine("{0} {1} ", result.Id, result.UserKey); }

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