I've got a university assignment and just need to know how to remove an entry from the address book and use it as a method
Here's what I have so far, everything's fine apart from the removing, please make it quite simple
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Assignment2
{
class Program
{
// strings for arrays
public static string name;
public static string name2;
public static string address;
public static string address2;
public static bool addressbookloop = false;
public static string selectioninput;
public static char selection;
static void addcontact(string[,] addressbook)
{
Console.WriteLine();
Console.WriteLine("You want to add a new entry");
Console.WriteLine("Press enter to continue");
Console.ReadLine();
Console.WriteLine("Please type in the contacts first name");
name = Console.ReadLine();
Console.WriteLine("And what is the contacts last name");
name2 = Console.ReadLine();
Console.WriteLine("Please type in the contacts house number and street name");
address = Console.ReadLine();
Console.WriteLine("Please type in the contacts town / city");
address2 = Console.ReadLine();
Console.WriteLine("CONTACT SAVED");
Console.WriteLine();
// Sending to Array
int i = 0; bool Xs = false;
do
{
if (addressbook[i, 0] == "XXXXXXX")
{
addressbook[i, 0] = name;
addressbook[i, 1] = name2;
addressbook[i, 2] = address;
addressbook[i, 3] = address2;
Xs = true;
}
else
{
i++;
}
} while (Xs == false);
}
static void removecontact(string[,] addressbook)
{
Console.WriteLine("Which contact do you want to delete");
Console.WriteLine("You wish to delete {0} {1}, {2} {3}'s address.", name, name2, address, address2);
Console.ReadLine();
}
static void showaddresses(string[,] addressbook)
{
Console.WriteLine("*** Address Book ***");
Console.WriteLine();
for (int i = 0; i < addressbook.GetLength(0); i++)
{
name = addressbook[i, 0];
name2 = addressbook[i, 1];
address = addressbook[i, 2];
address2 = addressbook[i, 3];
Console.WriteLine("{0} {1}, {2}, {3}", name, name2, address, address2);
}
Console.WriteLine();
Console.WriteLine("Press enter to go back to the homepage");
}
static void Main()
{
// starting array
string[,] addressbook = new string[10, 4];
for (int i = 0; i < addressbook.GetLength(0); i++)
{
for (int j = 0; j < addressbook.GetLength(1); j++)
{

}
}
do
{
Console.WriteLine("*** My Address Book ***");
Console.WriteLine();
Console.WriteLine("Which option would you like to choose");
Console.WriteLine();
Console.WriteLine("1. Add new entry");
Console.WriteLine("2. Remove entry");
Console.WriteLine("3. Show address book");
Console.WriteLine();
Console.WriteLine("Please enter your selection below");
selectioninput = Console.ReadLine();
selection = Convert.ToChar(selectioninput);
switch (selection)
{
case '1':
// Add Contact
addcontact(addressbook);
break;
case '2':
// Remove contact
removecontact(addressbook);
break;
case '3':
// Show addresses
showaddresses(addressbook);
Console.ReadLine();
break;
default:
Console.WriteLine("This is an invalid selection, Please Try Again");
Console.WriteLine();
break;
}
}

}
