How to use Distinct operator in LINQ

Introduction

Linq operator provides great flexibility and easy way of coding. Let’s again take one more example of distinct operator. As name suggest it will find the distinct elements from IEnumerable. Let’s take an example of array in console application and then we will again print array to see is it working or not. Below is the code for that. In this application I have integer array which contains duplicate elements and then I will apply distinct operator to this and then I will print again result of distinct operators to actually see whether its working or not.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace Experiment
{
   class Program
   {
       static void Main(string[] args)
       {
           int[] intArray = { 1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5 };
           var uniqueIntegers = intArray.Distinct();
           foreach (var uInteger in uniqueIntegers)
           {
               Console.WriteLine(uInteger);
           }
           Console.ReadKey();
 
       }
   }
}

Below is output as expected.

That’s cool.Stay tuned for more.Happy programming.
