Wave Financial ADO.NET Provider

Rapidly create and deploy powerful .NET applications that integrate with Wave Financial.



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 Wave Financial Data Provider.

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

    Connect using the API Token

    You can connect to Wave Financial by specifying the APIToken You can obtain an API Token using the following steps:

    1. Log in to your Wave account and navigate to "Manage Applications" in the left pane.
    2. Select the application that you would like to create a token for. You may need to create an application first.
    3. Click the "Create token" button to generate an APIToken.

    Connect using OAuth

    If you wish, you can connect using the embedded OAuth credentials. See the Help documentation for more information.

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

WaveFinancialEntities context = new WaveFinancialEntities(); var invoicesQuery = from invoices in context.Invoices select invoices; foreach (var result in invoicesQuery) { 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.
