如何在C#中使用LINQ比较两个List <String>

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

class Program
{
    static void Main()
    {
        List<string> list1 = new List<string> { "apple", "banana", "orange", "grape" };
        List<string> list2 = new List<string> { "orange", "watermelon", "grape", "pineapple" };

        // 比较两个列表并找出相同项
        var commonItems = list1.Intersect(list2);
        Console.WriteLine("相同项:");
        foreach (var item in commonItems)
        {
            Console.WriteLine(item);
        }

        // 比较两个列表并找出不同项
        var distinctItems = list1.Union(list2).Except(commonItems);
        Console.WriteLine("\n不同项:");
        foreach (var item in distinctItems)
        {
            Console.WriteLine(item);
        }
    }
}
