asp.net c#中对cookie写,读取,修改,删除等相关操作
//写cookie
HttpCookie cookie = new HttpCookie("Info");//定义cookie对象以及名为Info的项
cookie.Expires = DateTime.Now.AddDays(1);//添加cookie有效作用时间为1天
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");
}
//修改cookie
Response.Cookies["Info"]["user"] = "2";
Response.Cookies["Info"].Expires = DateTime.Now.AddDays(1);
// 删除cookie下的属性
var 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
acookie.Expires = DateTime.Now.AddDays(-1);
Response.Cookies.Add(acookie);
