C#:比较两个IEnumerables的内容

using System;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        IEnumerable<int> enumerable1 = new List<int> { 1, 2, 3, 4, 5 };
        IEnumerable<int> enumerable2 = new List<int> { 1, 2, 3, 4, 5 };
        IEnumerable<int> enumerable3 = new List<int> { 1, 2, 3, 4, 6 };

        bool areEqual = enumerable1.SequenceEqual(enumerable2);
        Console.WriteLine("Are enumerable1 and enumerable2 equal? " + areEqual);

        areEqual = enumerable1.SequenceEqual(enumerable3);
        Console.WriteLine("Are enumerable1 and enumerable3 equal? " + areEqual);
    }
}

Are enumerable1 and enumerable2 equal? True
Are enumerable1 and enumerable3 equal? False
