Streak ADO.NET Provider

Rapidly create and deploy powerful .NET applications that integrate with Streak.



LINQ provides general-purpose query facilities in .NET Framework 3.0 and above and provides one easy way to programmatically access data through from CData ADO.NET Data Providers. This example uses LINQ to access information from the Streak Data Provider.

This article demonstrates how to use LINQ to access Streak tables through the CData ADO.NET Data Provider for Streak. 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.

  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.
