生成的 WCF 代理为列表返回 null

Question

我们正在尝试为 PHP SOAP 服务实现 WCF 代理/客户端。 我们检索了 WSDL 并在命令行应用程序中创建了一个服务引用。 我们能够检索 SOAP 操作的结果，但事实证明，返回的列表总是以 null 结尾，当使用 fiddler 敲击线路或在 SoapUI 中对其进行测试时，我们可以清楚地看到正在返回的数据。

我在类似的问题帖子中遵循了一些建议，并提出了一个似乎存在相同问题的简约反序列化示例。

Message m = Message.CreateMessage(XmlReader.Create("response.xml"), int.MaxValue, MessageVersion.Soap11);
SoapReflectionImporter importer = new SoapReflectionImporter(new SoapAttributeOverrides(), "http://brokenns");
XmlTypeMapping mapping = importer.ImportTypeMapping(typeof(getDeviceListResponse));
XmlSerializer serializer = new XmlSerializer(mapping);
getDeviceListResponse response = (getDeviceListResponse)serializer.Deserialize(m.GetReaderAtBodyContents());
Console.WriteLine(response.@return.deviceList == null  ? "List is null" : "List is not null");

< List is null

任何人都可以发现服务 wsdl 中的错误会在反序列化后使我的列表为空吗？

我尝试对生成的合约进行简单的来回序列化，但无法在其中发现问题，这让我相信它与命名空间有关，但省略它们并没有帮助。

<?xml version="1.0" encoding="utf-16"?>
<getDeviceListResponse xmlns:ns1="http://brokenns">
  <return>
    <message>sd</message>
    <deviceList>
      <id>2323</id>
    </deviceList>
    <deviceList>
      <id>67</id>
    </deviceList>
  </return>
</getDeviceListResponse>

以下适用于序列化：

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

namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XmlReader reader = XmlReader.Create(FILENAME);
            XmlSerializer serializer = new XmlSerializer(typeof(Envelope));
            Envelope envelope = (Envelope)serializer.Deserialize(reader);

        }
    }
    [XmlRoot(ElementName = "Envelope", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
    public class Envelope
    {
        [XmlElement(ElementName = "Body", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
        public Body Body { get; set; }
    }
    public class Body
    {
        [XmlElement(ElementName = "getDeviceListResponse", Namespace = "http://brokenns")]
        public getDeviceListResponse getDeviceListResponse { get; set; }
    }
    public class getDeviceListResponse
    {
        [XmlElement(ElementName = "return", Namespace = "")]
        public Return Return { get; set; }
    }
    public class Return
    {
        public string message { get; set; }
        [XmlElement()]
        public List<deviceList> deviceList { get; set; }
    }
    public class deviceList
    {
        public int id { get; set; }
    }
}
