当名称空间前缀和xmlns前缀不等于

Question

您好我完全卡住了，我可以通过远程service.svc wsdl以某种方式获得响应。抱歉英语不好。 有我的工作样本，感谢 stackoverflow ：

using System;
using System.Xml;


namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {

            string responseXml =
                "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
                "<Envelope" +
                    " xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\"" +
                    " xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"" +
                    " xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">" +
                    "<soap:Body>" +
                       "<Company xmlns:b=\"http://www.someurl.com/Report/Company\">" +
                                "<b:LoginResult>" +
                                "<b:CookieName>FedAuth</b:CookieName>" +
                                "<b:ErrorCode>NoError</b:ErrorCode>" +
                                "<b:TimeoutSeconds>1800</b:TimeoutSeconds>" +
                                "<b:Parametrs>Zoroo 100</b:Parametrs>" +
                                "</b:LoginResult>" +
                        "</Company>" +
                    "</soap:Body>" +
                "</Envelope>";


            XmlDocument document = new XmlDocument();
            document.LoadXml(responseXml);  //loading soap message as string 
            XmlNamespaceManager manager = new XmlNamespaceManager(document.NameTable);


            manager.AddNamespace("b", "http://www.someurl.com/Report/Company");



            XmlNodeList xnList = document.SelectNodes("//b:LoginResult", manager);
            int nodes = xnList.Count;

            foreach (XmlNode xn in xnList)
            {
                string CookieName = xn["b:CookieName"].InnerText;
                string ErrorCode = xn["b:ErrorCode"].InnerText;
                string TimeoutSeconds = xn["b:TimeoutSeconds"].InnerText;
                string Parametrs = xn["b:Parametrs"].InnerText;

                Console.WriteLine();
                Console.WriteLine(CookieName + ErrorCode + TimeoutSeconds + Parametrs);
                Console.WriteLine();


            }


        }
    }

}

我的问题是，当我收到这样的消息时，我无法理解肥皂响应消息：

如果我的命名空间具有不同的前缀（a，b）而不是xmlns前缀，例如此处

，那么如何访问值

<a:Company xmlns:b="http://www.someurl.com/Company"> 

在manager.AddNamespace a:Company xmlns:b时，我无法弄清楚如何使用a,b,c 如何访问所有值root？
