无论出于何种原因,IBM都使用https(不需要凭据)来获取RSS源.我正在尝试使用.NET 4 SyndicationFeed 来使用https://www.ibm.com/developerworks/mydeveloperworks/blogs/roller-ui/rendering/feed/gradybooch/entries/rss?lang=en.我可以在浏览器中打开这个Feed,它加载得很好.这是代码:

        using (XmlReader xml = XmlReader.Create("https://www.ibm.com/developerworks/mydeveloperworks/blogs/roller-ui/rendering/feed/gradybooch/entries/rss?lang=en"))
        {
            var items = from item in SyndicationFeed.Load(xml).Items
                        select item;
        }

这是例外:

System.Net.WebException was unhandled by user code
Message=The remote server returned an error: (500) Internal Server Error.

我有编码问题.当我得到网站的源代码时,我有:

我将编码设置为UTF8,如下所示:

StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
            string sourceCode = reader.ReadToEnd();

谢谢你的帮助!
