如何在Seq中正确聚合对象？

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 = 25 },
            new Person { Name = "Bob", Age = 30 },
            new Person { Name = "Alice", Age = 35 },
            new Person { Name = "Bob", Age = 40 }
        };

        var groupedPeople = people.GroupBy(p => p.Name);

        foreach (var group in groupedPeople)
        {
            Console.WriteLine("Group: " + group.Key);
            foreach (var person in group)
            {
                Console.WriteLine("Name: " + person.Name + ", Age: " + person.Age);
            }
            Console.WriteLine();
        }
    }
}

Group: Alice
Name: Alice, Age: 25
Name: Alice, Age: 35

Group: Bob
Name: Bob, Age: 30
Name: Bob, Age: 40
