XML 转换为 Json 和 DeserializeObject 问题 - InfoPath 名称空间？

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，然后重新加载到 c# class。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 class 文件的定义上做更多的工作。为了生成 class 文件，我使用了 Visual Studio "paste as Json"。我假设在加载 XML、保存到 Json 之后，然后将其用作新 class 文件的基础，我可以直接加载回对象，但是当我调用 DeserializeObject 时，它总是最终为空。

这是因为 class 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？

    class Program
    {
        static void Main(string[] args)
        {
            XmlDocument myDoc = new XmlDocument();

            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);

Answer 1

使用 xml linq 尝试下面的代码：

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();
        }
    }
}

Answer 2

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);
