Delete Function of a Class

Delete Function of a Class

I'm having trouble with the delete function. I have everything working
except the delete function.
Any help would be appreciated. I've tried to change it a bit but it still
doesn't delete. I have no idea what the problem is with my remove
function.

{
private string name;
private string phoneNumber;

{
set { name = value; }
get { return name; }

Console.WriteLine();
Console.WriteLine(" Name: {0}", name);
Console.WriteLine(" Phone Number: {0}", phoneNumber);
Console.WriteLine();
