c# - 为 xml 反序列化自动创建的 C# 类不起作用

Question

我正在努力为这个 xml 创建反序列化类:

<?xml version="1.0" encoding="ISO-8859-1"?>
<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:stn="urn:response">
    <SOAP-ENV:Body>
        <Response>
            <Records xsi:type="SOAP-ENC:Array" SOAP-ENC:arrayType="stn:Record[1]">
                <item xsi:type="stn:Record">
                    <person xsi:type="xsd:string">John Johnos</person>
                    <address xsi:type="xsd:string">Some Street 1</address>
                    <age xsi:type="xsd:string">24</age>
                </item>
            </Records>
            <status xsi:type="SOAP-ENC:Array" SOAP-ENC:arrayType="stn:status[1]">
                <item xsi:type="stn:status">
                    <status xsi:type="xsd:string">success</status>
                    <message xsi:type="xsd:string"/>
                </item>
            </status>
        </Response>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

我尝试使用自动创建的代码(在 VisualStudio 12 中:编辑 -> 选择性粘贴 -> 将 XML 粘贴为类):

我尝试在 XMLSerializer 的帮助下反序列化:

var serializer = new XmlSerializer(typeof(Envelope));
var reader = new StringReader(response);
var flResponse = (Envelope)serializer.Deserialize(reader);

我得到的错误信息:

Message=The specified type was not recognized: name='Array', namespace='http://schemas.xmlsoap.org/soap/encoding/', at <Records xmlns=''>.

你能帮我为这个 xml 创建反序列化类吗？

Answer 1

我试了很多东西，终于弄明白了。您发布的 Xml 无效，因为 xsi:type 在反序列化中不起作用。

有效的 XML 应该如下所示:

<?xml version="1.0" encoding="ISO-8859-1"?>
<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:stn="urn:response">
    <SOAP-ENV:Body>
        <Response>
            <Records>
                <item>
                    <person >John Johnos</person>
                    <address >Some Street 1</address>
                    <age >24</age>
                </item>
            </Records>
            <status>
                <item>
                    <status >success</status>
                    <message/>
                </item>
            </status>
        </Response>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

代码应该是这样的:

XDocument xml = XDocument.Parse(xmlInput);

XmlSerializer serializer = new XmlSerializer(typeof(Response));

using (StringReader stream = new StringReader(items[0].ToString()))
{
    var output = (Response)serializer.Deserialize(stream);
}

自动生成类将来自:

<Response>
  <Records  xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <item>
      <person>John Johnos</person>
      <address >Some Street 1</address>
      <age>24</age>
    </item>
  </Records>
  <status xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <item >
      <status >success</status>
      <message />
    </item>
  </status>
</Response>

希望这已经足够清楚了。不确定如何从 Envelope 中删除类型，所以这可能不是您想要的解决方案。

我用于从 Envelope 获取内容的方法是 XDocument.Descendants(elemmentName)，它返回数组或该名称的元素列表，然后您可以填充对象。它的工作更多，但我认为它比转换 xml 以进行反序列化更好。
