ASP.NET操作Cookie

//创建
HttpCookie cookie = new HttpCookie("user","111");//创建Cookie
cookie Expires = DateTime.Now.Add(15);//设置过期时间
 Response.Cookies.Add(cookie);//存入客户端
我们取出Cookie值也很简单
string value = Request.Cookies["user"].value;
有时候我们想在一个Cookie中储存多个信息，那也没有问题。比如我们在名为user的cookie下加多个信息
HttpCookie cookie = new HttpCookie("user");
cookie.Values.Add("name","222");
cookie.Values.Add("pwd","333");
cookie.Values.Add("member","admin");
Response.Cookies.Add(cookie);
从客户端获取取信息也一样简单
HttpCookie cookie = Request.Cookies["user"];
value1 = cookies.Values["name"];
value2 = cookies.Values["pwd"];
