1. Create a C-Sharp project that stores personal information for a little electronic "black book". The fields in the file should include name, phone number, pager number, cell phone number, voice mail number, and e-mail address. Use text boxes to enter the data.

2. Create another C-Sharp project to load the names into a list box and use a structure to hold the fields of data. Perform a "look up" and display the appropriate information for the selected name.

Please comment the code for easy understanding.
