W8.1电话系统.Xml.XmlException＆amp; System.Reflection.TargetInvocationException

Question

我的程序崩溃并在尝试计算这些行时出现以下错误;

XmlReaderSettings settings = new XmlReaderSettings();
settings.DtdProcessing = DtdProcessing.Ignore;

XmlReader reader = XmlReader.Create(url, settings);
SyndicationFeed feed = SyndicationFeed.Load(reader);
reader.Close();

在这一行上它会破坏：XmlReader reader = XmlReader.Create（url，settings）;

感谢您的帮助，
