ASP.NET 生成 RSS Feed

2008-02-22 09:38:12来源：互联网阅读 ()

前段时间在写RSS Feed。
经过了几次的修改，把相关的代码写成了单独的类。
感觉重用时还算比较方便的。于是贴出来，大家一起研究研究。

以下是RssBase.cs类：

1using System;
2using System.Collections.Generic;
3using System.Xml;

5namespace MyMedia.Utilities
6{
7 public class RssBase
8 {
9 RssBase constructor#region RssBase constructor
10 public RssBase(XmlTextWriter rssWriter)
11 {
12 this.rssWriter = rssWriter;
13 }
14 public RssBase(XmlTextWriter rssWriter, bool hasMedia, IList<ItemInfo> items)
15 {
16 this.rssWriter = rssWriter;
17 this.hasMedia = hasMedia;
18 this.items = items;
