আসুন আরেকটি উদাহরণ দেখি -
using System;
using System.Collections;
public class Demo {
public static void Main() {
ArrayList arrList = new ArrayList();
arrList.Add(100);
arrList.Add(200);
arrList.Add(300);

arrList.Add(500);
Console.WriteLine("Display elements...");
IEnumerator demoEnum = arrList.GetEnumerator();
while (demoEnum.MoveNext()) {
Object ob = demoEnum.Current;
Console.WriteLine(ob);
}
arrList.Insert(4, 1000);
Console.WriteLine("Display elements...UPDATED");
demoEnum = arrList.GetEnumerator();
while (demoEnum.MoveNext()) {
Object ob = demoEnum.Current;
Console.WriteLine(ob);
}
}
