Your application uses LINQ to SQL to retrieve Product entities to display in a window. The window uses paging to display 25 results at a time. You add the following method:

public IEnumerable<Product> GetProducts(int pageNumber)
{
var query = from c in db.Customers
select c.CompanyName;
}

You need to add code to return only the subset of rows that will be shown on the page number given by pageNumber.

Which code segment should you add?
