问题描述
我正在为此XML创建反序列化类：
I am struggling to create deserialization classes for this xml:
<?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Visual Studio 12中：编辑->选择性粘贴->粘贴XML作为类）：

我试图在帮助下进行反序列化的XMLSerializer：
I tried to deserialize with help of XMLSerializer:
var serializer = new XmlSerializer(typeof(Envelope));
var reader = new StringReader(response);
var flResponse = (Envelope)serializer.Deserialize(reader);
我收到的错误消息：
Message=The specified type was not recognized: name='Array', namespace='http://schemas.xmlsoap.org/soap/encoding/', at <Records xmlns=''>.
您能帮我为该xml扩展反序列化类吗？
Could you please help me to greate deserialization classes for this xml?
推荐答案
我尝试了很多事情，最后弄清楚了。您发布的xml无效，因为xsi：type不能在反序列化中使用。
I tried a lot of thing and finaly figured it out. Xml you posted is invalid because xsi:type doesn't work in deserialization.
有效的XML应该如下所示：
Valid XML should look like:
<?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>
代码应如下所示：
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>
希望这很清楚。不知道如何摆脱信封的类型，所以，这可能不是您想要的解决方案。
Hope this is clear enough. Not sure how to get rid of types from Envelope so, this is probably not the solution you want.
我用来从信封中获取东西的方法是 XDocument.Descendants（elemmentName）返回该名称的数组或元素列表，然后可以填充对象。它的工作更多，但我认为它比转换xml进行反序列化更好。
Method i use for getting things from Envelope is XDocument.Descendants(elemmentName) which return array or List of elements of that name and then you can fill objects. Its more work, but i think its better than transforming xml for deserialization.
