Question

Create an application with a class named PersonEntry. The PersonEntry class should have properties for a person s name, e-mail address, and phone number. Also, create a text file that contains the names, e-mail addresses, and phone numbers for at least five people. When the application starts, it should read the data from the file and create a PersonEntry object for each person's data. The PersonEntry objects should be added to a List, and each person's name should be displayed in a list box on the application's main form. When the user selects a name from the list box, a second form should appear displaying that person's name, e-mail address, and phone number.

Explanation / Answer

{
class PersonEntry
{
  
public string PersonName { get; set; } //Creates a variable for the person's name.
public string PersonEmail { get; set; } //Creates a variable for the person's email.
public string PersonPhoneNumber { get; set; } //Creates a variable for the person's phone number.

}
}
