在 C# 中将 Soap XML 转换为 Json 对象

背景信息

我有两个 .net 服务(比如 A 和 B).服务 B 使用服务 A 的服务引用.这里使用的是basicHttpBinding".

I have two .net services (say A and B). Service B uses a service reference of Service A. Here, 'basicHttpBinding' is being used.

服务 A 中存在 global.asax.cs，我计划在将调用发送到服务 A.svc.cs 之前执行一些操作

There is a global.asax.cs present in Service A where I plan to perform some operations before the call is sent to Service A.svc.cs

我可以使用以下代码读取 global.asax.cs 中的请求正文.

I'm able to read request body in global.asax.cs using the following code.

StreamReader streamReader = new StreamReader(HttpContext.Current.Request.InputStream);
streamReader.BaseStream.Position = 0;
string message = streamReader.ReadToEnd();

'message' 字符串变量保存请求正文，即 xml 格式的有效负载.我可以使用以下代码读取 xml.

The 'message' string variable holds the request body i.e. payload in xml format. I'm able to read the xml using the following code.

XmlDocument doc = new XmlDocument();
doc.LoadXml(message);

xml 看起来像这样

<?xml version="1.0" encoding="UTF-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
   <s:Body>
      <FunctionName xmlns="http://tempuri.org/">
         <sampleString>value</sampleString>
         <sampleObject xmlns:a="http://schemas.datacontract.org/2004/07/contract" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
            <a:sampleProperty1>value1</a:sampleProperty1>
            <a:sampleProperty2>value2</a:sampleProperty2>
         </sampleObject>
      </FunctionName>
   </s:Body>
</s:Envelope>

问题

有没有办法把这个xml转换成json?我只对xml里面的数据感兴趣.

Is there any way to convert this xml to json? I'm only interested in the data inside in the xml.

额外问题

a:sampleProperty"中的a:"是什么意思/代表什么?

What does 'a:' in 'a:sampleProperty' mean / stand for?

期望输出

最终的json应该是这样的

The final json should like this

{
  "sampleString": "value",
  "sampleObject": {
    "sampleProperty1": "value1",
    "sampleProperty2": "value2"
  }
}

我尝试过的事情

我尝试使用代码删除顶级父节点及其属性.然后，我用 JsonConvert 将 xml 转换为 json

I have tried removing top parent nodes and their attributes using code. Then, I used to JsonConvert to convert xml to json

JsonConvert.SerializeXmlNode(doc.ChildNodes[0].ChildNodes[0].ChildNodes[0], Newtonsoft.Json.Formatting.None, true);

这样做只能部分帮助我，我以以下 json 输出结束

Doing this only helped me partially and I ended with the following json output

{
  "sampleString": "value",
  "sampleObject": {
    "@xmlns:a":"http://schemas.datacontract.org/2004/07/contract",
    "@xmlns:i":"http://www.w3.org/2001/XMLSchema-instance",
    "a:sampleProperty1": "value1",
    "a:sampleProperty2": "value2"
  }
}
