问题是您为 XmlDocument 使用了错误的命名空间(System.Xml).请使用 Windows.Data.Xml.Dom 命名空间.有关更多信息，您可以参考 XmlDocument 类官方文档.

The problem is that you have used wrong namespace(System.Xml) for XmlDocument. Please use Windows.Data.Xml.Dom namespace. For more you could refer to XmlDocument class official documentation.

using Windows.Data.Xml.Dom;

......

XmlDocument responseXML = new XmlDocument();
responseXML.LoadXml(response);
string innerText = responseXML.SelectNodes("//maininfo").Item(0).InnerText;

这是官方 XML DOM 示例，请检查.
