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));}
