XML 转换为 Json 和 DeserializeObject 问题 - InfoPath 命名空间？

Question

我正在考虑将大量 InfoPath XML 文件作为 Json 文件加载到 Cosmos DB 中，以测试可能的项目。但我正在努力将 XML 文件转换为 Json，然后加载回 c# 类。我认为这与 InfoPath 放入 XML 的命名空间有关，但我不确定。起初我想我应该尝试从 XML 中删除所有命名空间引用，但现在我想知道我是否只需要在类文件的定义上做更多工作。为了生成类文件，我使用了 Visual Studio“粘贴为 Json”。我假设在加载 XML 后，保存到 Json，然后使用它作为新类文件的基础，我可以直接加载回对象，但是当我调用 DeserializeObject 时，它总是以 null 结束。

这是因为类文件定义需要更改，还是我应该在转换为 Json 之前尝试清理 XML？

控制台测试代码

namespace xml_to_json
{
    class Program
    {
        static void Main(string[] args)
        {
            XmlDocument myDoc = new XmlDocument();
            string sourcedir = @"C:\Users\mystuff\Downloads\test-clean\";
            string xmlfilein = @"test";
            string xmlfile = string.Concat(sourcedir, xmlfilein, ".xml");
            string jsonfileout = string.Concat(sourcedir, xmlfilein, ".json");
            myDoc.Load(xmlfile);
            string jsonText = JsonConvert.SerializeXmlNode(myDoc.LastChild);
            File.WriteAllText(jsonfileout, jsonText);

            Rootobject obj = new Rootobject();
            obj = JsonConvert.DeserializeObject<Rootobject>(jsonText);
            Console.WriteLine(obj.mymyFields.myRequest_Status);   
        }   
    }

使用 xml linq 试试下面的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XDocument doc = XDocument.Load(FILENAME);

            XElement routingOrder = doc.Descendants().Where(x => x.Name.LocalName == "Routing_Order").FirstOrDefault();

            Dictionary<string, string> orders = routingOrder.Elements()
                .GroupBy(x => x.Name.LocalName, y => (string)y)
                .ToDictionary(x => x.Key, y => y.FirstOrDefault());

            string status = (string)doc.Descendants().Where(x => x.Name.LocalName == "Request_Status").FirstOrDefault();
            string requestType = (string)doc.Descendants().Where(x => x.Name.LocalName == "Request_Type").FirstOrDefault();
        }
    }
}

使用 jdweng 和 XDocument 的建议有助于清理 XML 文件，以便更轻松地过渡到 Json。下面是我用来清理文档的代码示例。

    XDocument newxdoc = XDocument.Load(xmlfile);
    newxdoc.DescendantNodes().Where(e => e.NodeType.ToString().StartsWith("ProcessingInstruction")).Remove();          
    string newstringdoc = RemoveAllNamespaces(newxdoc.ToString());
    newxdoc = XDocument.Parse(newstringdoc);
