            // Create and configure a new command.
            using (SqlCommand com = con.CreateCommand())
            {
                com.CommandType = CommandType.StoredProcedure;
                com.CommandText = "SalesByCategory";
    
                // Create a SqlParameter object for the category parameter.
                com.Parameters.Add("@CategoryName", SqlDbType.NVarChar).Value = 
                    category;
    
                // Create a SqlParameter object for the year parameter.
                com.Parameters.Add("@OrdYear", SqlDbType.NVarChar).Value = year;
    
                // Execute the command and process the results.
                using (IDataReader reader = com.ExecuteReader())
                {
                    Console.WriteLine("Sales By Category ({0}).", year);
    
                    while (reader.Read())
                    {
                        // Display the product details.
                        Console.WriteLine("  {0} = {1}",
                            reader["ProductName"],
                            reader["TotalPurchase"]);
                    }
                }
            }
        }
    }
