我正在尝试解决一个错误,我在http://captainobvio.us生成的所有RSS源在Internet Explorer(版本8和9)中产生以下错误:

Feed代码错误从当前编码切换到不支持的指定编码.行:1个字符:40

<?xml version="1.0" encoding="utf-16"?>

问题是通过HTTP标头发送的实际编码类型与文档声明的不同.以下是将代码输出写入HTML的代码:

public ContentResult Index()

            var feed = _syndication.SyndicateIdeas(_repository.GetIdeas(0,15).Ideas);

            var sb = new StringBuilder();

            {
                feed.SaveAsRss20(writer);
                writer.Close();
            }

            return Content(sb.ToString(), "application/rss+xml", Encoding.UTF8);
        } 

以下是我使用.NET 4.0中的System.ServiceModel.Syndication实际构建feed的代码:

var feed = new SyndicationFeed("CaptainObvio.us - Recent Ideas",
                                          "The most recent ideas posted by the Community on CaptainObvio.us", new Uri("http://captainobvio.us/"), "CaptainObvio.us", new DateTimeOffset(ideas[0].DatePosted), items)
                           {
                               Generator = …
