如何检查List<string>是否存在其他List<string>中的所有值

using System;
using System.Collections.Generic;

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

        bool containsAllValues = CheckIfListContainsAllValues(list1, list2);
        Console.WriteLine("List1 contains all values in List2: " + containsAllValues);
    }

    public static bool CheckIfListContainsAllValues(List<string> list1, List<string> list2)
    {
        foreach (string value in list1)
        {
            if (!list2.Contains(value))
            {
                return false;
            }
        }
        return true;
    }
}
