Your software development company wants to continue developing and enhance a software for internal use. The Software Development Company is now requesting that you add GUI/Windows form elements to the C# application.
 
Describe the design of your program. Include a flow chart or a UML Class diagram if you feel it will help you.
Include your source code here. 
This needs to be a paste of the text. Only include the code that you wrote. Not all of the Form code.

The following requirement list:
You are creating a Windows Forms Application using C# that reads a file of employees and loads it into an array.  Each record in the file needs to be loaded into an Developer Records Sub Class which has a super class of Employee Record.  Employee Tax type should be an object within Developer Records class and either be W2 or 1099.  Your program should have the following characteristics:

Logic flow is clear, concise, and effective
User inputs and outputs should be clear on screen
Validation for input types and data format
Appropriate indentation to logically illustrate program structure
Identifiers logically describe use
