LINQ: OfType Query Operator

LINQ comes with the OfType<T> query operator, through which we can filter the required object type from a heterogeneous array.

Suppose below is the scenario where we have array with various types but will only retrieve the string type. Here we go with ease of life,

using System;

using System.Collections.Generic;

using System.Text;

using System.Query;

using System.Xml.XLinq;

using System.Data.DLinq;

namespace LINQConsoleApplication1_Oct11

{

    class Program

    {

     static void Main(string[] args)

        {

            object[] numbers = {"Wriju", 28, 12/12/2006, 3.3f, 1, "Tupur", 8.0};

            var strs = numbers.OfType<string>();

            Console.WriteLine("The list of friends..");

            Console.WriteLine("==========================");

            foreach(var s in strs)

            {

                Console.WriteLine(s);

            }

            Console.ReadKey();

        }

    }

}

Output will look like
