Question

请问Cookie怎么在两个页面间传递数据？

Answer 1

参考代码如下：

//如果请求的Cookie对象为空
if (Request.Cookies["userCookie"] == null)
{
//创建一个Cookie对象
HttpCookie userCookie = new HttpCookie("userCookie");

//给对象赋值
userCookie.Values["userName"] =
userInfo.UserName.ToString();

userCookie.Values["lastVist"] =
DateTime.Now.ToString();

userCookie.Values["count"] = "1";

//设置对象的过期时间
userCookie.Expires = DateTime.Now.AddDays(30);

//添加到Cookies集合
Response.Cookies.Add(userCookie);
}
//不为空的情况
else
{
int counter =
Convert.ToInt32
(Request.Cookies["userCookie"]["count"]) + 1;
HttpCookie userCookie =
new HttpCookie("userCookie");
userCookie.Values["userName"] =
userInfo.UserName.ToString();
userCookie.Values["lastVist"] =
DateTime.Now.ToString();
userCookie.Values["count"] =
counter.ToString();
userCookie.Expires =
DateTime.Now.AddDays(30);
Response.Cookies.Add(userCookie);
}

Answer 2

使用Response将cookie写入客户端，而使用Request读取客户端的cookie。所以，第二个页面中读取cookie应写成下面这样：
HttpCookie temp = Request.Cookies["newcookie"];
