使用RavenDB 4LINQ提供程序查找两个列表的交集

using Raven.Client.Documents;
using System;
using System.Collections.Generic;
using System.Linq;

public class Program
{
    public static void Main()
    {
        // 创建RavenDB会话对象
        using (var session = DocumentStoreHolder.Store.OpenSession())
        {
            // 定义两个列表
            var list1 = new List<int> { 1, 2, 3, 4, 5 };
            var list2 = new List<int> { 4, 5, 6, 7, 8 };

            // 使用LINQ查询语法查找交集
            var intersection = session.Query<Item>()
                .Where(item => list1.Contains(item.Id))
                .Intersect(session.Query<Item>()
                    .Where(item => list2.Contains(item.Id)))
                .ToList();

            // 输出交集结果
            Console.WriteLine("交集结果：");
            foreach (var item in intersection)
            {
                Console.WriteLine(item.Id);
            }
        }
    }
}

// 定义一个实体类
public class Item
{
    public int Id { get; set; }
}

// 创建RavenDB数据库连接
public static class DocumentStoreHolder
{
    private static readonly Lazy<IDocumentStore> LazyStore =
        new Lazy<IDocumentStore>(() =>
        {
            var store = new DocumentStore
            {
                Urls = new[] { "http://localhost:8080" },
                Database = "YourDatabaseName"
            };
            return store.Initialize();
        });

    public static IDocumentStore Store => LazyStore.Value;
}
