Asp.net实现网站的RSS功能

RSS是共享内容的一种简易方式,也称聚合.通常被用于新闻和Blog。网站提供RSS输出，有利于让用户发现网站内容的更新。网站用户可以借助于支持RSS的新闻聚合工具软件或者在线网站（如BLOGLINES），订阅网站的内容并在不打开网站页面的情况下阅读内容。

闲话少说,步入正题!

创建新项目,新建Rss.aspx页,因为XML文件内容的输出是采用直接输出字符串的形式，只留下面这一行即可

1 <%@ Page Language=\”C#\” AutoEventWireup=\”true\” CodeBehind=\”Rss.aspx.cs\” Inherits=\”MyVs2008.Rss\” %>
2 后台代码；Rss.aspx.cs
3 protected void Page_Load(object sender, EventArgs e)
4 {
5 Response.ContentType = \”text/xml\”;
6 Response.Charset = \”UTF-8\”;
7 Response.Write(\”<?xml version=\\\”1.0\\\” encoding=\\\”UTF-8\\\” ?>\”);
8 Response.Write(\”<rss version=\\\”2.0\\\”><channel>\”);
9 Response.Write(GetUserRSS(GetMovie()));
10 Response.Write(\”</channel></rss>\”);
11 }
