LINQ - usage of SequenceEqual method

In this article we are going to the usage of SequenceEqual method. Let we see the example how it is works.

            /*Find the equal of two sequence */

            var seq1 = new List<int>() {1,6,3,21};

            var seq2 = new List<int>() {4,6,21,3,5};

            var seq3 = new List<int>() { 3, 6, 21, 1 };

            var seq4 = new List<int>() { 1, 6, 3, 21 };

            Console.WriteLine(seq1.SequenceEqual(seq2));

Output:

     False

The output for the above code is false, because the values present in seq1 and seq2 is different.

            Console.WriteLine(seq1.SequenceEqual(seq3));  

Output:

      False

The output for the above code is false, because the values present in seq1 and seq3 is same but are in different sequence.

         

            Console.WriteLine(seq1.SequenceEqual(seq4));

Output:

       True

The output for the above code is True, because the values present in seq1 and seq4 is same and also in sequence.
