参数

[beihangyan]

请问各位，基础问题：
HttpCookies oldCookie = Request.Cookies["userIP"];
....
HttpCookies newCookie = new HttpCookie("userIP");
问题是对于参数userIP在这里分别表示啥意思;加[]和()区别是啥?
谢谢!!

1、Request.Cookies["userIP"]获取cookies集合中名为userIP的值
2、new HttpCookie("userIp")实例化了一个HttpCookie

是实例化，我知道，但是这里实例化传递了参数"userIP”,这个参数是干嘛用的?

[smartxue1987]

HttpCookie c = new HttpCookie("dayfrom");
c.Value = dayfrom;
c.Values.Clear();
c.Expires = DateTime.Now.AddDays(-1);
Response.Cookies.Add(c);

取Cookie值时就这样写
Request.Cookies["dayfrom"].Value
明白了吗

谢谢各位，我在MSDN中查着了。
