cookie操作

今天有空就把操作cookie的写了,虽然很简单,不过免得到时候忘记了。
        下面是写cookie
 HttpCookie cookie = new HttpCookie("Info");//定义cookie对象以及名为Info的项
 DateTime dt = DateTime.Now;//定义时间对象
 TimeSpan ts=new TimeSpan(1,0,0,0);//cookie有效作用时间,具体查msdn
 cookie.Expires = dt.Add(ts);//添加作用时间
 cookie.Values.Add("user","cxbkkk");//增加属性
 cookie.Values.Add("userid","1203");
 Response.AppendCookie(cookie);//确定写入cookie中        读取cookie
  if(Request.Cookies["Info"]!=null)
  {
      string temp=Convert.ToString(Request.Cookies["Info"].Values["user"])+"  "+Convert.ToString(Request.Cookies["Info"].Values["userid"]);
     //读全部就用Request.Cookies["Info"].Value)
     if(temp=="")
      {
          Response.Write("空");
      }
      else
         Response.Write(temp);
 }
 else
 {
     Response.Write("error");
 }       // 改cookie
 Response.Cookies["Info"]["user"] = "2";
 Response.Cookies["Info"].Expires = DateTime.Now.AddDays(1);        //删除cookie下的属性
 HttpCookie acookie=Request.Cookies["Info"];
 acookie.Values.Remove("userid");
 acookie.Expires = DateTime.Now.AddDays(1);
 Response.Cookies.Add(acookie);        //删除所有cookie,就是设置过期时间为现在就行了
 int limit=Request.Cookies.Count - 1;
 for(int i=0;i<limit;i++)
 {
     acookie = Request.Cookies(i)
     acookie.Expires = DateTime.Now.AddDays(-1)
     Response.Cookies.Add(acookie)
 }
