.net读取cookie中的值

登陆页面：Response.Cookies["id"].Value = loginnum.Text;
Response.Cookies["id"].Expires = DateTime.Now.AddDays(1);
转入的页面：
HttpCookie acookie = Request.Cookie("id");
Label1.Text = acookie.Value;

该怎么写呢 烦死了 搜索网上的方法都不行 不是不包含cookie的定义就是未引用到对象 帮帮忙 谢谢了
lipt1845你好 读取出来的还是空 怎么弄啊

Answer 1

你好：
写入方法：
HttpCookie cookie = new HttpCookie("id");
cookie.Value=cookieValue;
cookie.Expires = DateTime.Now+new TimeSpan(0,1,0,0));
Response.Cookies.Add(cookie);
读取方法：
HttpCookie cookie = Request.Cookies["id"];
if(null == cookie)
{
Label1.Text = "";
}
else
{
Label1.Text = cookie.Value;
}

Answer 2

if (Request.Cookies["id"]!=null)
Label1.Text=Request.Cookies["id"].Value;
