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));
}
