mvc cookie

（1）设置

HttpCookie user = new HttpCookie("User");

            user["ID"] = Session["ID"].ToString();

            user["UID"] = Session["UID"].ToString();            

 HttpContext.Current.Response.Cookies.Add(user);

（2）取出

HttpContext.Current.Request.Cookies["User"].Values["ID"]

HttpContext.Current.Request.Cookies["User"].Values["UID"]

（3）用法

比如建立一个名为aspcn，值为灌水小鱼的cookie

HttpCookie cookie = new HttpCookie["aspcn"];
cookie.Value = "灌水小鱼";
Response.AppendCookie(cookie);

取出Cookie值也很简单

HttpCookie cookie = Request.Cookies["aspcn"];
cookieValue = cookie.Value;

在一个Cookie中储存多个信息，那也没有问题。比如在名为aspcn的cookie下加多个信息

HttpCookie cookie = new HttpCookie("aspcn");
cookie.Values.Add("webmaster","灌水小鱼");
cookie.Values.Add("writer","beige");
cookie.Values.Add("LinkColor","blue");
Response.AppendCookie(cookie);

取出信息也一样简单

HttpCookie cookie = Request.Cookies["aspcn"];
value1 = cookies.Values["webmaster"];
