C#如何在多个列表中找到唯一值(如果有)

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

class Program
{
    static void Main(string[] args)
    {
        List<int> list1 = new List<int> { 1, 2, 3, 4, 5 };
        List<int> list2 = new List<int> { 4, 5, 6, 7, 8 };

        var uniqueValues = list1.Intersect(list2);

        if (uniqueValues.Any())
        {
            Console.WriteLine("唯一值：");
            foreach (var value in uniqueValues)
            {
                Console.WriteLine(value);
            }
        }
        else
        {
            Console.WriteLine("没有唯一值。");
        }
    }
}
