本文介绍了如何在ASP.NET应用程序中实现Cookie的写入和读取功能。通过示例代码展示了创建并设置Cookie属性的方法，以及如何从客户端请求中获取已设置的Cookie信息。
1.写入Cookie,在Page_Load事件添加代码如下:
HttpCookie nc = new HttpCookie("newcookie");
nc.Values["name"] = "大气象";
nc.Values["age"] = "27";
nc.Values["dt"] = DateTime.Now.ToString();
Response.Cookies.Add(nc);
Response.Write("Cookie写入成功!");
2.读出Cookie,为按钮添加事件代码如下:
//通过Request.Cookies["newcookie"];方法获得Cookie拷贝.
HttpCookie getcook = Request.Cookies["newcookie"];
//通过getcook.Values["变量名"]取得Cookie其中一个变量的值.
Response.Write(getcook.Values["name"]);
Response.Write("<br>"+getcook.Values["age"]);
Response.Write("<br>"+getcook.Values["dt"]);
HttpCookie nc = new HttpCookie("newcookie");
nc.Values["name"] = "大气象";
nc.Values["age"] = "27";
nc.Values["dt"] = DateTime.Now.ToString();
Response.Cookies.Add(nc);
Response.Write("Cookie写入成功!");
2.读出Cookie,为按钮添加事件代码如下:
//通过Request.Cookies["newcookie"];方法获得Cookie拷贝.
HttpCookie getcook = Request.Cookies["newcookie"];
//通过getcook.Values["变量名"]取得Cookie其中一个变量的值.
Response.Write(getcook.Values["name"]);
Response.Write("<br>"+getcook.Values["age"]);
Response.Write("<br>"+getcook.Values["dt"]);
