LINQ Cast() Method

In LINQ, Cast operator is used to cast/convert all the elements present in a collection into a specified data type of new collection. In case if we try to cast/convert different types of elements (string/integer) in the collection, then the conversion will fail, and it will throw an exception.

Example of LINQ Cast Conversion Operator

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
//create an object named 'obj' of ArrayList 
            ArrayList obj = new ArrayList();
//assign the values to the object 'obj' 
            obj.Add("USA");

            obj.Add("Australia");

            obj.Add("UK");

            obj.Add("India");
//Here we are converting the ArrayList object to String type of object and store the result in 'result'

            IEnumerable<string> result = obj.Cast<string>();
//Now with the help of foreach loop we will print the value of result
            foreach (var item in result)

            {

                Console.WriteLine(item);

            }

            Console.ReadLine();

        }

    }
}

Output:

In the above example, we have an Arraylist where we added a few countries. These countries are a type of Object, and by using Cast operator, we are converting the ArrayList Object to String type object.
