<>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 (sample was uploaded as an attachment).

 

<>The file should not be 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.

 

*Sorted data based on last name

*Sorted data based on ZIP

*Everyone in the state of NY
