关于用SyndicationFeed类生成Rss的问题，请高手指教

Question

怎么让它生成的rss带有<?xml version="1.0" encoding="utf-8"?> 这句话

??

Answer 1

这个类的SaveXXXX方法有个参数 XmlWriter类
设置XmlWriter的Settings属性的
XmlWriterSettings.OmitXmlDeclaration =true


SyndicationFeed feed = new SyndicationFeed("Feed Title", "Feed Description", new Uri("http://Feed/Alternate/Link"), "FeedID", DateTime.Now);
// ...
XmlWriter xmlWriter = XmlWriter.Create("TestRSSFile.xml");
xmlWriter.Settings.OmitXmlDeclaration=true;
feed.SaveAsRss20(xmlWriter);

Answer 2

 public SyndicationFeedFormatter SearchArticle(string text)
        {
            SyndicationFeed feed = new SyndicationFeed(
               "aa:" + text,
               "aa:" + text,
               new Uri("http://tempuri.org/"));
            XmlQualifiedName aa = new XmlQualifiedName("aa");
            feed.AttributeExtensions.Add(aa, "bb");
           
            List<SyndicationItem> items = new List<SyndicationItem>();
            for (int i = 0; i < 5; i++)
            {               
               SyndicationItem item = new SyndicationItem(
                    "aa" + text + i,
                    "aa" + text + i,
                    new Uri("http://tempuri.org/ArticleUri" + text + i),
                    "000000000" + i,
                    DateTime.Now);
                    items.Add(item);
            }
            feed.Items = items;
            return new Rss20FeedFormatter(feed);

那如果我这么写呢，能不能加上<?xml version="1.0" encoding="utf-8"?> 这句话??

Answer 3

你的这一步不控制 是否输出xml声明

而是在你处理SyndicationFeed 保存xml的时候或者 SyndicationFeedFormatter WriteTo的时候 设置XmlWriter的设置的时候可以控制
