C#

Write a program that displays a graphical user interface (Windows form) that allows multiple names, e-mail addresses, and local phone numbers to be entered. Allow only numbers to be entered for the phone number. Retrieve and store the values entered by the user in a text file and then ready the GUI for the next set of input values. Store each person’s data on separate lines. Include appropriate exception-handling techniques in your solution. When the application closes, locate the text file and verify its contents.
