Step 1: Given a file of data, read the data and parse it based on a fixed given field headers. To download the file, select the following link: Unit 4 Sample Data. Eliminate the last column (Pig-Latin) in the data file.

 The file is a comma delimited file with the following record structure:

• FirstName – Character – Size (12)
• LastName – Character – Size (16)
• Company – Character – Size (32)
• Address – Character – Size (32)
• City – Character – Size (24)
• County – Character – Size (24)
• State – Character – Size (2)
• ZIP – Number – Size (5)
• Phone – Character – Size (12)
• Fax – Character – Size (12)
• Email – Character – Size (32)
• Web – Character – Size (42)

Step 2: Write a complete C# program in console mode to load the data file as a sequential file using C# System.IO library into an ArrayList data structure (using the System.Collection library) Store each line in the file as a separate record.

Step 3: After the file is loaded into the ArrayList, sort the data in ascending order based on the LastName field and Display the following fields:

• First name
• Last name
• Company

Step 4: Next, sort the data in descending order based on the ZIP field, and display the following fields:

• First name
• Last name
• Company
• ZIP

Step 5: Display all the records (and all its fields) for everyone that is in the state “NY.”

Step 6: Submit the source code for the solution and the output screenshots for the following list. You can use any appropriate algorithm in the solution.

1. Sorted data based on last name
2. Sorted data based on ZIP
3. Everyone in the state of NY
