How to Search for an Item in an ASP.NET C# ArrayList

Searching for an item in a C# ArrayList is fairly simple. The only thing you need to do is loop through the ArrayList. Once the item in the collection is found, you break out of the loop. In the example below, if the item you are searching for is not found, I return a "not found" message.

First, I am using the Use the Add() method or object initializer syntax to add elements in an ArrayList. When I run the application, I use the console application and a C# Console.ReadLine() method to take input from the user. 

using System.Collections;

namespace ConsoleAppFun
{
    class Examples
    {
        static void Main()
        {
            ArrayList AddSyllables = new ArrayList();
            AddSyllables.Add("ia");
            AddSyllables.Add("riet");
            AddSyllables.Add("dien");
            AddSyllables.Add("ien");
            AddSyllables.Add("iet");
            AddSyllables.Add("iu");
            AddSyllables.Add("iest");
            AddSyllables.Add("io");
            AddSyllables.Add("ii");
            AddSyllables.Add("ily");
            AddSyllables.Add(@".oala\b");
            AddSyllables.Add(@".iara\b");
            AddSyllables.Add(@".ying\b");
            AddSyllables.Add(".earest");
            AddSyllables.Add(".arer");

            string found = "was not found";
            string searchString = Console.ReadLine();

            foreach (string item in AddSyllables)
            {
                if (item == searchString?.Trim())
                {
                    found = "was found";                    
                    break;
                }
            }
            Console.WriteLine("This string " + found + " in the array: " + searchString);
        }
    }
}

If I type iest into the console app, this is the found message I receive. 

If I type ilikepickles into the console app, this is the not found message I receive. 

That's it!
