LINQ to WooCommerce Data

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 WooCommerce Data Provider.

This article demonstrates how to use LINQ to access WooCommerce tables through the CData ADO.NET Data Provider for WooCommerce. 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 WooCommerce Data Source".
  4. Enter your data source connection information.

    WooCommerce supports the following authentication methods: one-legged OAuth1.0 Authentication and standard OAuth2.0 Authentication.

    Connecting using one-legged OAuth 1.0 Authentication

    Specify the following properties (NOTE: the below credentials are generated from &service; settings page and should not be confused with the credentials generated by using WordPress OAuth2.0 plugin):

    • ConsumerKey
    • ConsumerSecret

    Connecting using WordPress OAuth 2.0 Authentication

    After having configured the plugin, you may connect to WooCommerce by providing the following connection properties:

    • OAuthClientId
    • OAuthClientSecret
    • CallbackURL
    • InitiateOAuth - Set this to either GETANDREFRESH or REFRESH

    In either case, you will need to set the Url property to the URL of the WooCommerce instance.

    Below is a typical connection string:

    Url=https://example.com/; ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad; ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5; InitiateOAuth=GETANDREFRESH
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting WooCommerceEntities 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:

WooCommerceEntities context = new WooCommerceEntities(); var ordersQuery = from orders in context.Orders select orders; foreach (var result in ordersQuery) { Console.WriteLine("{0} {1} ", result.Id, result.ParentId); }

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