今天有空就把操作cookie的寫了，雖然很簡單，不過免得到時候忘記了，之前就是忘記了還很實驗了一番才弄出來，郁悶了。
下面是寫cookie
1 httpcookie cookie = new httpcookie("info");//定義cookie對象以及名為info的項
2 datetime dt = datetime.now;//定義時間對象
3 timespan ts=new timespan(1,0,0,0);//cookie有效作用時間，具體查msdn
4 cookie.expires = dt.add(ts);//添加作用時間
5 cookie.values.add("user","cxbkkk");//增加屬性
6 cookie.values.add("userid","1203");
7 response.appendcookie(cookie);//確定寫入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，就是設置過期時間為現在就行了
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
