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); // } } } Output Perls More details checkout bellow links http://www.dotnetperls.com/arraylist http://stackoverflow.com/questions/17937884/what-is-the-graceful-way-to-remove-an-element-from-c-sharp-arraylist-in-a-loop http://stackoverflow.com/questions/11083884/remove-item-from-arraylist-doesnt-work-properly
