LINQ to Copper Data

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

4. Enter your data source connection information.

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

   Copper API Profile Settings

   In Copper CRM, go to Settings > Integrations > API Keys and click Generate API Key. Provide both the API key and the email address associated with your account.

   Below is a typical connection string:

   Profile=C:\profiles\Copper.apip;ProfileSettings='APIKey=your_api_key;UserEmail=your_email';


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 accountQuery = from account in context.Account
  select account;

foreach (var result in accountQuery) {
  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.
