任何人都有C#MVC的出生日期验证属性？

using System;
using System.ComponentModel.DataAnnotations;

public class BirthDateAttribute : ValidationAttribute
{
    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {
        DateTime birthDate;
        if (value != null && DateTime.TryParse(value.ToString(), out birthDate))
        {
            if (birthDate > DateTime.Now)
            {
                return new ValidationResult("出生日期不能大于当前日期");
            }
        }
        return ValidationResult.Success;
    }
}

public class Person
{
    [BirthDate(ErrorMessage = "请输入有效的出生日期")]
    public DateTime BirthDate { get; set; }
}

public class HomeController : Controller
{
    public IActionResult Index()
    {
        var person = new Person();
        return View(person);
    }

    [HttpPost]
    public IActionResult Index(Person person)
    {
        if (ModelState.IsValid)
        {
            // 验证通过，执行相应的逻辑
            return RedirectToAction("Success");
        }
        return View(person);
    }

    public IActionResult Success()
    {
        return View();
    }
}
