C# Program -- 2

Write a program that: • Makes use of a class called Customer which stores the information for one single customer. • You must use the methods in the UML diagram (Figure 1). You may not use class properties. • Reads the data in this csv [login to view URL] data file into an array of your Customer class. • There can potentially be any number of records in the data file up to a maximum of 100. • You must use an array of Customers. You may not use an ArrayList • Prompts the user to pick one of six menu options: o Sort by Customer Name (ascending) o Sort by Customer Id (ascending) o Sort by Product Name (descending) o Sort by Quantity (descending) o Sort by Sales Total (descending) o Exit • Displays a neat, orderly table of all five items of customer information in the appropriate sort order, properly formatted • Continues to prompt until the user selects the exit options • A Read() method that reads all customer information into the array and has exception checking • Error checking for user input. • salesTotal is calculated as quantity * productSalePrice - discount. If the quantity is greater than or equal to 100 apply a 5% discount. If the quantity is greater than or equal to 250 apply a 12.5% discount. • The Main() method should be highly modularized • The Customer class should include proper data and methods as provided by the given UML class diagram to the right. • No input or output should be done by any part of the Customer class itself. • You may download this sample program for a demonstration of program behaviour
