Response.Cookies.Add()和方法Response.AppendCookie()有什么区别?-CSDN社区

特别说明请注意：根许多网友反应， using Maticsoft.Functions; 这些代码看不懂其实Functions 这个dll是我定义常用的函数类，如果需要跟我联系索取http://sql8.net 下面有我的群号，其中 ArtsShop.Model.Arts_Product _p = new ArtsShop.Model.Arts_Product(); ArtsShop.BLL.Arts_Product p = new ArtsShop.BLL.Arts_Product(); _p = p.GetModel(id); 这是我的商品信息的类，三层结构，这个在用时你们只能换成你们自己的，这些代码完全可以删除，比如 MyDr[1] = _p.Title; 用来读取商品名的，你们可以改MyDr[1] = dr["productname"].ToString();就行了， AddToCart.aspx页面代码无标题页保存取消编辑继续购物清空购物车下订单 AddToCart.aspx.cs页面代码 using System;

代码如下://第一种添加Cookie方法 HttpCookie myCookie = new HttpCookie(“userrole”); myCookie.Values[“a”] = “a”; myCookie.Values[“”] = “b”; myCookie.Expires.AddDays(1); Response.Cookies.Add(myCookie); //Response.AppendCookie(mycookie);这个也可以添加 //第一种获取Cookie方法

asp.net操作cookie的例子，包括创建cookie、读取cookie、清空cookies，有需要的朋友可以参考下。 1、创建cookie 代码如下: HttpCookie cookie = new HttpCookie(“AutoLogin”); cookie.Values.Add(“name”, user.UserName); cookie.Values.Add(“pass”, user.Password); cookie.Expires = DateTime.Now.AddDays(1); Response.AppendCookie(cookie); 2、读取cookie 代

服务器向客户端发送设置Cookie时，可用HttpResponse.SetCookie、HttpResponse.AppendCookie、HttpResponse.Cookies.Add这三个家伙。简单描述下他们的区别（注意红色部分）： HttpResponse.Cookies.Add：将指定 cookie添加到Cookies集合，同key的cookie可以重复添加，总是添加而不
