将cXML反序列化为C＃类

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了将cXML反序列化为C＃类相关的知识，希望对你有一定的参考价值。

我正在尝试将cXML字符串反序列化为C＃类。但是，在反序列化时，除了根元素之外，我似乎什么也无法得到。 How to Deserialize XML document似乎提供了最大的帮助，在该示例中，我设法对根cXML标记进行反序列化，但这不适用于嵌套对象PunchOutSetupRequest，这是我真正需要反序列化的对象。

我的问题，在向您展示代码墙之前，如何在不更改cXML.cs文件的情况下，将这些对象正确地反序列化为下面定义的cXML类？由于这是一个标准，除非绝对必要，否则我不想编辑它。我的代码是公平的游戏。预先感谢您的任何帮助，因为我知道该主题在SO的各个角落都有涉及。

我有用于cXML的XSD文件，我已经使用xsd.exe工具将其转换为C＃类。为了避免稀释问题，我不会在此处粘贴整个架构，但是如果需要更完整的图片，可以转到cxml.org。

我的cXML代码仅反序列化属性，不包含cXML中定义的Header或Request对象：

using (TextReader reader = new StringReader(text))
            {
                try
                {
                    XmlRootAttribute xRoot = new XmlRootAttribute();
                    xRoot.ElementName = "cXML";
                    xRoot.IsNullable = true;
                    var serializer = new XmlSerializer(typeof(cXML), xRoot);
                    cxml = (cXML)serializer.Deserialize(reader);
                }
                catch (Exception ex)
                {
                    string r = "";
                }
            }

我的PunchOutSetupRequest反序列化代码。尽管我将xRoot元素设置为PunchOutSetupRequest，但当将cXML视为根节点时，这将引发错误。

using (TextReader reader = new StringReader(text))
            {
                try
                {
                    XmlRootAttribute xRoot = new XmlRootAttribute();
                    xRoot.ElementName = "PunchOutSetupRequest";
                    xRoot.IsNullable = true;
                    var serializer = new XmlSerializer(typeof(PunchOutSetupRequest), xRoot);
                    PunchOutSetupRequest request;
                    request = (PunchOutSetupRequest)serializer.Deserialize(reader);
                }
                catch (Exception ex)
                {
                    string r = "";
                }
            }

我正在尝试将cXML字符串反序列化为C＃类。但是，在反序列化时，除了根元素之外，我似乎什么也无法得到。似乎如何反序列化XML文档...
