XmlWriter ':'字符(十六进制值0x3A)不能包含在名称中

Question

我正在使用 XmlWriter 并收到以下错误：

Invalid name character in 'news:news'. The ':' character, hexadecimal value 0x3A, cannot be included in a name.

有谁知道是什么原因造成的？这是我的代码：

using (XmlWriter writer = XmlWriter.Create("moo.xml"))
            {               
                writer.WriteStartDocument();
                writer.WriteStartElement("urlset", "http://www.sitemaps.org/schemas/sitemap/0.9");
                writer.WriteAttributeString("xmlns", "news", null, "http://www.google.com/schemas/sitemap-news/0.9");

                writer.WriteStartElement("url");
                writer.WriteElementString("loc", "http://www.monkeys.co.uk");
                writer.WriteStartElement("news:news");
                writer.WriteEndElement();
                writer.WriteEndElement();

                writer.WriteEndElement();
                writer.WriteEndDocument();
            }

您需要使用采用两个参数的重载WriteStartElement：

writer.WriteStartElement("news", "http://www.google.com/schemas/sitemap-news/0.9");
//               Tag   ----^       ^--- Namespace
