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");
}
