C# multi-value cookies not working

C# multi-value cookies not working

Hi I am creating a cookie in the following way:
HttpCookie cookie = new HttpCookie("CookieNameHere");
cookie.Values["test1"] = "Value1";
cookie.Values["test2"] = "Value2";
cookie.Values["test3"] = "Value3";
//I have also tried cookie.Values.Add("test1", "Value1");
cookie.Expires = DateTime.Now.AddDays(365d);
HttpContext.Current.Response.AppendCookie(cookie); //here I have also
tried HttpContext.Current.Response.Cookies.Add(cookie);
but when I read out the cookie using the following code:
HttpCookie cookie = new HttpCookie("CookieNameHere");
cookie = HttpContext.Current.Response.Cookies["CookieNameHere"];
I always get that the cookie.Values is empty
Is there something I am doing wrong here?
