Insert new data into the array and Delete data from the array

Hi Sarah,


Try this...


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    //class Program
    //{
    //    static void Main(string[] args)
    //    {
    //    }
    //}
    public delegate int Comparer(object obj1, object obj2);

    public class Name
    {
        public string FirstName = null;
        public string LastName = null;

        public Name(string first, string last)
        {
            FirstName = first;
            LastName = last;
        }

        // this is the delegate method handler
        public static int CompareFirstNames(object name1, object name2)
        {
            string n1 = ((Name)name1).FirstName;
            string n2 = ((Name)name2).FirstName;

            if (String.Compare(n1, n2) > 0)
            {
                return 1;
            }
            else if (String.Compare(n1, n2) < 0)
            {
                return -1;
            }
            else
            {
                return 0;
            }
        }

        public override string ToString()
        {
            return FirstName + " " + LastName;
        }
    }

    class SimpleDelegate
    {
        Name[] names = new Name[5];

        public SimpleDelegate()
        {
           
            names[0] = new Name("Ali", "Kaya");
            names[1] = new Name("Ali", "Tarak");
            names[2] = new Name("Ali", "Yilmaz");
            names[3] = new Name("Derya", "Birant");
            names[4] = new Name("Zeynep", "Ak");
        }

        static void Main(string[] args)
        {
            SimpleDelegate sd = new SimpleDelegate();

            // this is the delegate instantiation
            Comparer cmp = new Comparer(Name.CompareFirstNames);

            Console.WriteLine("\nBefore Sort: \n");

            sd.PrintNames();

            // observe the delegate argument
            sd.Sort(cmp);

            Console.WriteLine("\nAfter Sort: \n");

            sd.PrintNames();
        }

        // observe  the delegate parameter
        public void Sort(Comparer compare)
        {
            object temp;

            for (int i = 0; i < names.Length; i++)
            {
                for (int j = i; j < names.Length; j++)
                {
                    // using delegate "compare" just like
                    // a normal method
                    if (compare(names[i], names[j]) > 0)
                    {
                        temp = names[i];
                        names[i] = names[j];
                        names[j] = (Name)temp;
                    }
                }
            }
        }

        public void PrintNames()
        {
            Console.WriteLine("Names: \n");

            foreach (Name name in names)
            {
                Console.WriteLine(name.ToString());
               
            }
            Console.ReadLine();
        }
    }
}
