Can't Set and Get cookie using C# under ASP.NET MVC

Question

I'm trying to set and read cookies in c#. I wrote these two methods:

public static void setCookie(string sCookie, string value)
{
    HttpCookie cookie = HttpContext.Current.Request.Cookies[sCookie];
    if (cookie == null)
        cookie = new HttpCookie(sCookie);
    cookie.Value = value;
    cookie.Expires = DateTime.Now.AddYears(1);
    HttpContext.Current.Request.Cookies.Add(cookie);
}

public static string getCookie(string sCookie)
{
    if (HttpContext.Current.Request.Cookies[sCookie] == null)
        return null;
    return HttpContext.Current.Request.Cookies[sCookie].Value;
}

But I don't know why when I read the method getCookie, after calling setCookie, the collection HttpContext.Current.Request.Cookies contains always 2 elements, "__RequestVerificationToken" and "ASP.NET_SessionId", it doesn't contain my cookies...

Methods are not in any controller, just in a utils class, but I don't see any problem for that...

Can you figure out why my set method doesn't work? Thank you!

将cookie设置为Response对象，还设置cookie的路径
