using System;
using System.Collections.Generic;
using System.Linq;
class Program
{
    static void Main()
    {
        // 创建一个包含商品信息的字典，键为商品名称，值为标签数组
        Dictionary products = new Dictionary
        {
            { "Laptop", new[] { "Electronics", "High Performance", "Durable" } },
            { "Smartphone", new[] { "Electronics", "Portable", "Smart" } },
            { "Headphones", new[] { "Electronics", "Audio", "Comfortable" } },
            // 添加更多商品...
        };
        // 要搜索的标签数组
        string[] searchTags = { "Electronics", "High Performance" };
        // 使用LINQ进行搜索
        var matchingProducts = products
            .Where(product => searchTags.All(tag => product.Value.Contains(tag)))
            .ToDictionary(product => product.Key, product => product.Value);
        // 输出匹配的商品
        Console.WriteLine("匹配的商品：");
        foreach (var product in matchingProducts)
        {
            Console.WriteLine($"{product.Key}: {string.Join(", ", product.Value)}");
        }
    }
