反序列化XML / GPO？

分类：编程问答

如何解决反序列化XML / GPO？

我尝试使用C＃读取GPO。到目前为止，我收到以下XML字符串：

"<?xml version=\"1.0\" encoding=\"utf-16\"?>\r\n<GPO xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"

现在我想阅读它/想读出一些值。例如，如果我想从“ MaxServiceAge”（值是600）中读取值，该怎么办？

最好的问候， 亨德里克

使用Xml Linq：

        static void Main(string[] args)
        {
            string xml = File.ReadAllText(FILENAME);
            XDocument doc = XDocument.Parse(xml);

            List<XElement> xAccounts = doc.Descendants().Where(x => x.Name.LocalName == "Account").ToList();
            XNamespace q1 = xAccounts.FirstOrDefault().GetNamespaceOfPrefix("q1");

            Dictionary<string,Account> accountDict = xAccounts.Select(x => new Account()
