ASP.NET核心:如何将对象保存到控制器中的列表中

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

public class HomeController : Controller
{
    // 用于存储Person对象的列表
    private List<Person> personList = new List<Person>();

    // GET: Home
    public IActionResult Index()
    {
        return View(personList);
    }

    // POST: Home/AddPerson
    [HttpPost]
    public IActionResult AddPerson(Person person)
    {
        if (ModelState.IsValid)
        {
            person.Id = personList.Count + 1; // 简单的ID生成策略
            personList.Add(person);
            return RedirectToAction("Index");
        }
        else
        {
            return View("Index", personList);
        }
    }
}

@model List<Person>

<h2>Persons List</h2>
<ul>
    @foreach (var person in Model)
    {
        <li>@person.Name, @person.Age</li>
    }
</ul>

<form asp-action="AddPerson" method="post">
    <input type="text" name="Name" placeholder="Name" required />
    <input type="number" name="Age" placeholder="Age" required />
    <button type="submit">Add Person</button>
</form>
