关于asp.net c#中对cookie的操作

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，之前就是忘记了还很实验了一番才弄出来，郁闷了。 下面是写cookie1 HttpCookie cookie = new HttpCookie("Info");//定义cookie对象以及名为Info的项2 DateTime dt = DateTime.Now;//定义时间对象3 TimeSpan ts=new TimeSpan(1,0,0,0);//cookie有效作用时间，具体查msdn4 cookie.Expires = dt.Add(ts);//添加作用时间5 cookie.Values.Add("user","cxbkkk");//增加属性6 cookie.Values.Add("userid","1203");7 Response.AppendCookie(cookie);//确定写入cookie中 读取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 //读全部就用Request.Cookies["Info"].Value) 5 if(temp=="") 6 { 7 Response.Write("空"); 8 } 9 else10 Response.Write(temp);11 }12 else13 {14 Response.Write("error");15 } 修改cookie1 Response.Cookies["Info"]["user"] = "2";2 Response.Cookies["Info"].Expires = DateTime.Now.AddDays(1); 删除cookie下的属性1 HttpCookie acookie=Request.Cookies["Info"];2 acookie.Values.Remove("userid");3 acookie.Expires = DateTime.Now.AddDays(1);4 Response.Cookies.Add(acookie); 删除所有cookie，就是设置过期时间为现在就行了1 int limit=Request.Cookies.Count - 1;2 for(int i=0;i
