can you compare two lists c# code example

Example 1: check two lists are equal c#

List<int> list1 = new List<int> { 1, 2, 3 };
List<int> list2 = new List<int> { 1, 2, 3 };

if (list1.SequenceEqual(list2))
{
  Console.WriteLine("true");
}
else
{
  Console.WriteLine("false");
}

Example 2: i comparer for lists c#

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

namespace YourProject.Extensions
{
    public static class ListExtensions
    {
        public static bool SetwiseEquivalentTo<T>(this List<T> list, List<T> other)
            where T: IEquatable<T>
        {
            if (list.Except(other).Any())
                return false;
            if (other.Except(list).Any())
                return false;
            return true;
        }
    }
}
