RSS

RSS(也叫聚合内容，Really Simple Syndication)是一种描述和同步网站内容的格式，是目前使用最广泛的XML应用。个人认为，它就是资源共享模式的延伸。

 用asp.net实现RSS功能非常简单。好了，直接贴代码吧，建立Article.aspx，然后代码如下：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Article.aspx.cs" Inherits="Web.rss.Article"%><%@ OutputCache Duration="600" VaryByParam="none"%><?xml version="1.0" encoding="gb2312" ?>  
<rss version="2.0">  
<channel>  
<title><![CDATA[www.SvnHost.cn最新文章]]></title>  
<link>http://www.SvnHost.cn</link>  
<description><![CDATA[专业SVN托管服务-源代码版本管理-SVN Hosting Service]]></description>  
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">  
<ItemTemplate>  
<item id="<%# Container.ItemIndex + 1%>">  
<title><![CDATA[<%# Eval("title")%>]]></title>  
<tags><![CDATA[<%# Eval("tag")%>]]></tags>  
<link>http://www.svnhost.cn/Article/<%# Eval("id")%>.shtml</link>  
<description><![CDATA[<%# Eval("contents")%>]]></description>  
</item>  
</ItemTemplate>  
</asp:Repeater>  
</channel>  
</rss>  
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:db %>"  
SelectCommand="SELECT TOP 50 * FROM [t_Article] ORDER BY [id] DESC">  
</asp:SqlDataSource>

后台CS代码如下：

 

using System;  
using System.Data;  
using System.Configuration;  
using System.Collections;  
using System.Web;  
using System.Web.Security;  
using System.Web.UI;  
using System.Web.UI.WebControls;  
using System.Web.UI.WebControls.WebParts;  
using System.Web.UI.HtmlControls;  
  
namespace Web.rss  
{  
    publicpartialclass Article : System.Web.UI.Page  
    {  
        protectedvoid Page_Load(object sender, EventArgs e)  
        {  
            Response.ContentType ="text/xml";  
        }  
    }  
}
