C# ArrayList

C# ArrayList is used when there is a need for variable size array:

using System;
using System.Collections;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            ArrayList List1 = new ArrayList();
            ArrayList List2 = new ArrayList();
            List1.Add("B");
            List1.Add("A");
            List1.Add("C");
            Console.WriteLine("Shows Added valuess");
            ShowArray(List1);
            //insert 
            List1.Insert(3, "D");
            //sort ms in an arraylist
            List1.Sort();
            ShowArray(List1);
            //remove 
            List1.Remove("B");
            //remove from a specified index
            List1.RemoveAt(1);
            Console.WriteLine("Shows final values in the ArrayList");
            ShowArray(List1);

            //Add one ArrayList to second one
            List2.Add("X");
            List2.Add("Y");
            List2.Add("Z");

            List1.AddRange(List2);
            ShowArray(List1);

            //RemoveRange
            List1.RemoveRange(1, 3);
            ShowArray(List1);

            //foreach
            foreach ( string Value in List2)
            {
                Console.WriteLine(Value);
            }

            Console.ReadLine();

        }
        public static void ShowArray(ArrayList anArray)
        {
            int i;
            for (i = 0; i <= anArray.Count - 1; i++)
            {
                Console.WriteLine(anArray[i].ToString());
            }
            Console.ReadLine();

C# Virtual

The  virtual  keyword is used to modify a method, property, indexer, or event declaration and allow for it to be overridden in a derived class. For example, this method can be overridden by any class that inherits it. public virtual double Area() { return x * y; } When a virtual method is invoked, the run-time type of the object is checked for an overriding member. The overriding member in the most derived class is called, which might be the original member, if no derived class has overridden the member. By default, methods are non-virtual. You cannot override a non-virtual method. You cannot use the  virtual  modifier with the  static ,  abstract, private , or  override  modifiers. Click here for more info.
