Hi,

C# program that uses Insert and Remove
using System;
using System.Collections;
class Program
{
static void Main()
{
//
// Create an ArrayList with three strings.
//
ArrayList list = new ArrayList();
list.Add("Dot");
list.Add("Net");
list.Add("Perls");
//
// Remove middle element in ArrayList.
//
list.RemoveAt(1); // It becomes [Dot, Perls]
//
// Insert word at the beginning of ArrayList.
//
list.Insert(0, "Carrot"); // It becomes [Carrot, Dot, Perls]
//
// Remove first two words from ArrayList.
//
list.RemoveRange(0, 2);
//
// Display the result ArrayList.
//
foreach (string value in list)
{
Console.WriteLine(value); // <-- "Perls"
}
}
}
Output
Perls

Hi, When your adding to array list in dynamically at the time u can check or once display data /Retrieve data from array list check like

ArrayList list = new ArrayList();

list.Add("Dot");

list.Add("Net");

list.Add("Perls");

foreach (string value in list)

if(value=="Dot"){

 continue;

else{

   Console.WriteLine(value); // <-- "Perls"
