LINQ to Landbot Data

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

4. Enter your data source connection information.

   Using API Key Authentication

   Landbot uses token-based authentication. Obtain your agent token from Settings > Account in your Landbot account.

   Set the following connection properties:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your Landbot agent token.

   Sample Connection String

   Profile=C:\profiles\Landbot.apip;AuthScheme=APIKey;APIKey=your_agent_token_here;
   

   Below is a typical connection string:

   Profile=C:\profiles\Landbot.apip;AuthScheme=APIKey;APIKey=your_agent_token_here;


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 agentsQuery = from agents in context.Agents
  select agents;

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

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