LINQ to ChargeOver Data

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

4. Enter your data source connection information.

   Start by setting the Profile connection property to the location of the ChargeOver Profile on disk (e.g. C:\profiles\Chargeover.apip). Next, set the ProfileSettings connection property to the connection string for ChargeOver (see below).

   ChargeOver API Profile Settings

   Log into ChargeOver, navigate to Settings > Developer > REST API, enable the API, and copy your Public Key (APIKey) and Private Key (APISecret).

   Below is a typical connection string:

   Profile=C:\profiles\Chargeover.apip;ProfileSettings='APIKey=your_public_key;APISecret=your_private_key;Domain=your_subdomain';

👁 Required connection properties for the data source. (QuickBooks is shown.)

5. If saving your entity connection to App.Config, set an entity name. In this example we are setting APIEntities 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:

APIEntities context = new APIEntities();

var adminworkersQuery = from adminworkers in context.AdminWorkers
 select adminworkers;

foreach (var result in adminworkersQuery) {
 Console.WriteLine("{0} {1} ", result.Id, result.Id);
}

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