    return View();

HttpPost

[HttpPost]

{
    // create cookie
    HttpCookie preference = new HttpCookie("mypreference");
    preference.Value = ss["preffer"];
    preference.Expires = DateTime.Now.AddDays(120d);
    Response.Cookies.Add(preference);

视图

@using (Html.BeginForm("seotips", "home", FormMethod.Post))

Answer 1

你必须尝试这个

public ActionResult Index()
{
   HttpCookie coo = new HttpCookie("name");


    coo["Country"] = "INDIA";


    ViewData["prefvalue"] = coo["Country"];
    return View();
}

在ViewData页面中未设置mvc3 cookie值
