asp.net cookies的使用方法

Response.Cookie("username").value="aa" 写入

username=Request.Cookies("username").value 读取

最好用SESSION比较方便

session("username")="aa" 写入

username=session("username") 读取

C# :

方法1:

Response.Cookies["username"].Value="gjy";

Response.Cookies["username"].Expires=DateTime.Now.AddDays(1);

方法2:

System.Web.HttpCookie newcookie=new HttpCookie("username");

newcookie.Value="gjy";

newcookie.Expires=DateTime.Now.AddDays(1);

Response.AppendCookie(newcookie);

创建带有子键的cookies:

System.Web.HttpCookie newcookie=new HttpCookie("user");

newcookie.Values["username"]="gjy";

newcookie.Values["password"]="111";

newcookie.Expires=DateTime.Now.AddDays(1);

Response.AppendCookie(newcookie);

cookies的读取:

无子键读取:

if(Request.Cookies["username"]!=null)

{

Response.Write(Server.HtmlEncode(Request.Cookies["username"].Value));

}

有子键读取:

if(Request.Cookies["user"]!=null)

{

Response.Write(Server.HtmlEncode(Request.Cookies["user"]["username"].Value));

}
