Smartsheet ADO.NET Provider

Easy-to-use Smartsheet client enables .NET-based applications to easily consume Smartsheet Sheets, Contacts, Folders, Groups, Users, etc.



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 Smartsheet Data Provider.

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

    Smartsheet uses the OAuth authentication standard. To authenticate using OAuth, you will need to register an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties.

    However, for testing purposes you can instead use the Personal Access Token you get when you create an application; set this to the OAuthAccessToken connection property.

    Below is a typical connection string:

    OAuthClientId=MyOauthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting SmartsheetEntities 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:

SmartsheetEntities context = new SmartsheetEntities(); var sheet_event_plan_budgetQuery = from sheet_event_plan_budget in context.Sheet_Event_Plan_Budget select sheet_event_plan_budget; foreach (var result in sheet_event_plan_budgetQuery) { Console.WriteLine("{0} {1} ", result.Id, result.TaskName); }

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