使用连接将linq查询转换为lambda查询

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

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

public class Program
{
    public static void Main()
    {
        List<Person> people = new List<Person>
        {
            new Person { Name = "Alice", Age = 35 },
            new Person { Name = "Bob", Age = 25 },
            new Person { Name = "Charlie", Age = 40 }
        };

        // LINQ查询语法
        var namesLINQ = from person in people
                        where person.Age > 30
                        select person.Name;

        // Lambda查询语法
        var namesLambda = people.Where(person => person.Age > 30)
                                 .Select(person => person.Name);

        Console.WriteLine("LINQ查询结果:");
        foreach (var name in namesLINQ)
        {
            Console.WriteLine(name);
        }

        Console.WriteLine("\nLambda查询结果:");
        foreach (var name in namesLambda)
        {
            Console.WriteLine(name);
        }
    }
}
