       今天有空就把操作cookie的寫(xiě)了，雖然很簡(jiǎn)單，不過(guò)免得到時(shí)候忘記了，之前就是忘記了還很實(shí)驗(yàn)了一番才弄出來(lái)，郁悶了。
        下面是寫(xiě)cookie
1 HttpCookie cookie = new HttpCookie("Info");//定義cookie對(duì)象以及名為Info的項(xiàng)
2 DateTime dt = DateTime.Now;//定義時(shí)間對(duì)象
3 TimeSpan ts=new TimeSpan(1,0,0,0);//cookie有效作用時(shí)間，具體查msdn
4 cookie.Expires = dt.Add(ts);//添加作用時(shí)間
5 cookie.Values.Add("user","cxbkkk");//增加屬性
6 cookie.Values.Add("userid","1203");
7 Response.AppendCookie(cookie);//確定寫(xiě)入cookie中        讀取cookie
1 if(Request.Cookies["Info"]!=null)
2 {
3     string temp=Convert.ToString(Request.Cookies["Info"].Values["user"])+" "+Convert.ToString(Request.Cookies["Info"].Values["userid"]);
4     //讀全部就用Request.Cookies["Info"].Value)
5     if(temp=="")
6     {
7         Response.Write("空");
8     }
9     else
10         Response.Write(temp);
11 }
12 else
13 {
14     Response.Write("error");
15 }        修改cookie
1 Response.Cookies["Info"]["user"] = "2";
2 Response.Cookies["Info"].Expires = DateTime.Now.AddDays(1);        刪除cookie下的屬性
1 HttpCookie acookie=Request.Cookies["Info"];
2 acookie.Values.Remove("userid");
3 acookie.Expires = DateTime.Now.AddDays(1);
4 Response.Cookies.Add(acookie);        刪除所有cookie，就是設(shè)置過(guò)期時(shí)間為現(xiàn)在就行了
1 int limit=Request.Cookies.Count - 1;
2 for(int i=0;i<limit;i++)
3 {
4     acookie = Request.Cookies(i)
5     acookie.Expires = DateTime.Now.AddDays(-1)
6     Response.Cookies.Add(acookie)
7 }        這下不用到處找了
