LINQ to MYOB AccountRight Data

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

4. Enter your data source connection information.

   These properties are required when connecting to a company file (both for Cloud and On-Premise instances).

   • CompanyFileId: You can find this by starting MYOB, opening your data file, and selecting Help -> About MYOB
   • User: The username associated with your company file.
   • Password: The password associated with your company file.

   Connecting to a Cloud Instance

   To connect to a cloud instance of MYOB, you can use the embedded OAuth credentials or create an OAuth app with MYOB. This process is detailed in the Help documentation.

   Connecting to an On-Premise instance:

   When connecting to an on-premise instance, set the following connection property in addition to those above:

   • InitiateOauth: Set this to OFF.
   • Url: The Url of your MYOB instance.

   Below is a typical connection string:

   OAuthClientId=YourClientId; OAuthClientSecret=YourClientSecret; CompanyFileId=yourCompanyFileId; CallbackURL=http://localhost:33333; User=companyFileUser; Password=companyFilePassword;InitiateOAuth=GETANDREFRESH;

👁 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 MYOBEntities 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:

MYOBEntities context = new MYOBEntities();

var accountsQuery = from accounts in context.Accounts
 select accounts;

foreach (var result in accountsQuery) {
 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.
