The ArrayList works the same as Array but it can dynamically resize and has methods to
add and remove elements in the collection
It has the following methods:

- Add() method to add the elements

- Remove () method to remove the elements

Example 3: ArrayList collection adding and removing the element.

using System;
namespace SampleProgram {
class MySample {
public static void Main(string[] args) {
ArrayList arrList = new ArrayList();
arrList.Add(100);
arrList.Add(true);
arrList.Add( " Hi ");
arrList.Add(23.5);
foreach(object m in arrList) {
Console.Write($ " {
m
} ");
}
Console.WriteLine();
Console.WriteLine(arrList.Capacity);
arrList.Remove(true);
foreach(object m in arrList) {
Console.Write($ " {
m
} ");
}
}
}
}
