The examples in this topic demonstrate how to use the xref:System.Linq.Enumerable.ThenBy%2A method to query the AdventureWorks Sales Model using method-based query syntax. The AdventureWorks Sales Model used in these examples is built from the Contact, Address, Product, SalesOrderHeader, and SalesOrderDetail tables in the AdventureWorks sample database.
The examples in this topic use the following using/Imports statements:
[!code-csharp[DP L2E Examples#ImportsUsing](../../../../../../samples/snippets/csharp/VS_Snippets_Data/DP L2E Examples/CS/Program.cs#importsusing)] [!code-vb[DP L2E Examples#ImportsUsing](../../../../../../samples/snippets/visualbasic/VS_Snippets_Data/DP L2E Examples/VB/Module1.vb#importsusing)]
The following example in method-based query syntax uses xref:System.Linq.Queryable.OrderBy%2A and xref:System.Linq.Queryable.ThenBy%2A to return a list of contacts ordered by last name and then by first name.
[!code-csharp[DP L2E Examples#OrderByThenBy_MQ](../../../../../../samples/snippets/csharp/VS_Snippets_Data/DP L2E Examples/CS/Program.cs#orderbythenby_mq)] [!code-vb[DP L2E Examples#OrderByThenBy_MQ](../../../../../../samples/snippets/visualbasic/VS_Snippets_Data/DP L2E Examples/VB/Module1.vb#orderbythenby_mq)]
The following example uses the xref:System.Linq.Queryable.OrderBy%2A and xref:System.Linq.Queryable.ThenByDescending%2A methods to first sort by list price, and then perform a descending sort of the product names.
