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 Reckon Accounts Hosted Data Provider.

This article demonstrates how to use LINQ to access Reckon Accounts Hosted tables through the CData ADO.NET Data Provider for Reckon Accounts Hosted. 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 Reckon Accounts Hosted Data Source".

  4. Enter your data source connection information.

    The connector makes requests to Reckon Accounts Hosted through OAuth. Specify the following connection properties:

    • SubscriptionKey: Required. You get this value when you created your developer account.
    • CountryVersion: Defaults to 2021.R2.AU.
    • CompanyFile: Required. The path to the company file.
    • User: Required. The username of the company file.
    • Password: Required. The password of the company file.
    • InitiateOAuth: Set this to GETANDREFRESH to let the driver handle access tokens.
    • CallbackURL: The redirectURI of your Custom OAuth App.
    • OAuthClientId: The client id of your Custom OAuth App.
    • OAuthClientSecret: The client secret of your Custom OAuth App.

    CData provides an embedded OAuth application that simplifies OAuth desktop authentication. See the Help documentation for information on other OAuth authentication methods (web, headless, etc.), creating custom OAuth applications, and reasons for doing so.

    Below is a typical connection string:

    SubscriptionKey=my_subscription_key;CountryVersion=2021.R2.AU;CompanyFile=Q:/CompanyName.QBW;User=my_user;Password=my_password;CallbackURL=http://localhost:33333;OAuthClientId=my_oauth_client_id;OAuthClientSecret=my_oauth_client_secret;InitiateOAuth=GETANDREFRESH
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting ReckonAccountsHostedEntities 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:

ReckonAccountsHostedEntities context = new ReckonAccountsHostedEntities(); var accountsQuery = from accounts in context.Accounts select accounts; foreach (var result in accountsQuery) { Console.WriteLine("{0} {1} ", result.Id, result.Name); }

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