Use the Contains() method to determine if the string 'text' is in the ArrayList

    
using  System;
using  System.Collections;

class  MainClass

    public  static  void  Main()
    {
        ArrayList  myArrayList  =  new  ArrayList();
        myArrayList.Add("A");
        myArrayList.Add("A");

        myArrayList.Add("A");
        myArrayList.Add("A");
        myArrayList.Add("A");
        myArrayList.Add("A");
        myArrayList.Add("A");
        myArrayList.Add("A");
        myArrayList.Add("A");
        

        string[]  anotherStringArray  =  {"Here's",  "some",  "more",  "text"};
        myArrayList.SetRange(0,  anotherStringArray);


        if  (myArrayList.Contains("text"))
        {
            int  index  =  myArrayList.IndexOf("text");
            Console.WriteLine("myArrayList  does  contain  the  word  'text'");
            Console.WriteLine("'text'  first  occurs  at  index  "  +  index);
            index  =  myArrayList.LastIndexOf("text");
