The SequenceEqual method is used to compare two collections or lists of elements sequences that are equal or not. It compares two elements pair-wise and sees elements that are matched are not. It returns the Boolean value. 

Syntax

 collection1.SequenceEqual( collection2);

Example

using System;
using System.Collections.Generic;
using System.Linq;
public class Program
{
 public static void Main()
 {
  List<string> count1= new List<string>() { 'UK', 'Australia', 'India', 'USA' };
  List<string> count2 = new List<string>() { 'India', 'UAE', 'Canada', 'UK', 'China', 'Pok' };
  bool flag  = count1.SequenceEqual(count2);
  Console.WriteLine('List are {0} same ', !flag ? 'not' : '');
  List<string> count3= new List<string>() { 'UK', 'Australia', 'India', 'USA' };
  List<string> count4 = new List<string>() { 'UK', 'Australia', 'India', 'USA'};
  bool flag1  = count3.SequenceEqual(count4);
  Console.WriteLine('List are {0}same ', !flag1 ? 'not ' : '');
  Console.ReadLine();
 }
}

Output

List are not same 
List are same
