在即时窗口中使用Newtonsoft序列化对象的IEnumerable会砍掉结果

using Newtonsoft.Json;
using System;
using System.Collections.Generic;

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

public class Program
{
    public static void Main()
    {
        IEnumerable<Person> people = new List<Person>
        {
            new Person { Name = "Alice", Age = 25 },
            new Person { Name = "Bob", Age = 30 }
        };

        string json = JsonConvert.SerializeObject(people);
        Console.WriteLine(json);
    }
}
