In this chapter you will learn:

How to use Except operator
Except with String array

Get to know Except operator

Except returns the elements in the first input sequence that are not present in the second:

using System;/*from  ja  va2s  .  c o  m*/
using System.Collections;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main()
    {
        int[] seq1 = { 1, 2, 3 };
        int[] seq2 = { 3, 4, 5 };

        IEnumerable<int> difference1 = seq1.Except(seq2);
        IEnumerable<int> difference2 = seq2.Except(seq1);

        foreach (int i in difference1)
        {
            Console.WriteLine(i);
        }
        foreach (int i in difference2)
        {
            Console.WriteLine(i);
        }
    }
}

The output:

Except with String array

using System;// ja v  a 2  s.  co  m
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Text;


public class MainClass{

   public static void Main(string[] args){   
         String[] First = { "One", "Two", "Two", "Three", "Four" };
         String[] Second = { "Three", "Four", "Five", "Six" };

         var ShowExcept = First.Except(Second);

         Console.WriteLine("Except:");
         foreach (String ThisElement in ShowExcept)
            Console.WriteLine(ThisElement);

   }
}
