如何在ASP.NET MVC控制器中访问Request.cookies？

using System.Web;
using System.Web.Mvc;

public class HomeController : Controller
{
    public ActionResult Index()
    {
        HttpCookie cookie = Request.Cookies["cookieName"];

        if (cookie != null)
        {
            string cookieValue = cookie.Value;
            // 使用cookieValue进行处理
        }

        return View();
    }
}

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;

public class HomeController : Controller
{
    public IActionResult Index()
    {
        string cookieValue = Request.Cookies["cookieName"];

        if (!string.IsNullOrEmpty(cookieValue))
        {
            // 使用cookieValue进行处理
        }

        return View();
    }
}
