无法以编程方式反序列化 SOAP 消息

Question

当我尝试反序列化肥皂消息时，出现以下异常。我这样做是因为我有想要在测试中重用的响应文件。我无法使用真正的服务等，因为它不适合我们拥有的测试框架的架构。

    Test 'MyUnitTestMethod' failed: System.InvalidOperationException : There is an error in XML document (1, 2).
----> System.InvalidOperationException : <MySpecialResponse xmlns='http://xsd.com/msgs/v1'> was not expected. 
at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle, XmlDeserializationEvents events) 
at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle) 
at System.Xml.Serialization.XmlSerializer.Deserialize(Stream stream)


private const string _content =
@"<soapenv:Envelope xmlns:soapenv=""http://schemas.xmlsoap.org/soap/envelope/"">
  <soapenv:Body>
    <ns3:MySpecialResponse xmlns:ns3=""http://xsd.com/msgs/v1"" >
      <header>
        <status>0</status>
      </header>
      <ns3:Payload>
        <ns3:CustomerName>name</ns3:CustomerName>
        <ns3:EmailAddress>[email protected]</ns3:EmailAddress>
      </ns3:Payload>
    </ns3:MySpecialResponse>
  </soapenv:Body>
</soapenv:Envelope>";

            this.customerNameField = value;
        }
    }

    /// <remarks/>
    public string EmailAddress {
        get {
            return this.emailAddressField;
        }
        set {
            this.emailAddressField = value;
        }
    } 
}

//The code I am using - might not be right?
  var serialiser = new System.Xml.Serialization.XmlSerializer(typeof(MySpecialResponse));


  using (var stream = new MemoryStream(Encoding.ASCII.GetBytes(_content))
  { 
      var doc = new System.Xml.XmlDocument();
      doc.Load(stream);

      var nsManager = new System.Xml.XmlNamespaceManager(doc.NameTable);
      nsManager.AddNamespace("soapenv", "http://schemas.xmlsoap.org/soap/envelope/");

      //so I can get the actual response and not the soap body
      var node = doc.SelectSingleNode("//soapenv:Body", nsManager);

      if (node != null)
      {
           byte[] xml = Encoding.UTF8.GetBytes(node.InnerXml);
           using (var memStream = new System.IO.MemoryStream(xml))
           {
                memStream.Position = 0;
                var resp = (MySpecialResponse)serialiser.Deserialize(memStream);  //Throws exception here
            }
      }
  }

（BaseResponse 具有标头字段）

我的异常发生的任何想法以及如何获取肥皂消息以将消息反序列化到对象中，无论是修复我的代码还是应用其他技术。

注意：我有很多文件想要使用通用方法进行反序列化，因此我不会提前知道所有 xml 命名空间，只知道根响应类型。

谢谢

好的，我已经自己解决了。

我需要为 XmlSerializer 添加 XmlRootAttribute

var xRoot = new System.Xml.Serialization.XmlRootAttribute();
xRoot.ElementName = "MySpecialResponse";
xRoot.IsNullable = true;
xRoot.Namespace = rootResponseNamespace;

var serialiser = new System.Xml.Serialization.XmlSerializer(typeof(MySpecialResponse), xRoot);
