我正在开发Windows应用商店。
我有以下手动创建的Fault类:
[XmlRoot(Namespace = "http://schemas.xmlsoap.org/soap/envelope/", ElementName = "Fault")]
public partial class SoapFault
{
[XmlElement(Form = XmlSchemaForm.Unqualified, ElementName = "faultcode")]
public String FaultCode { get; set; }
[XmlElement(Form = XmlSchemaForm.Unqualified, ElementName = "faultstring")]
public String FaultDescription { get; set; }
[XmlElement(Form = XmlSchemaForm.Unqualified, ElementName = "detail")]
public InnerException[] Detail { get; set; }
}
[XmlType(Namespace = "http://my.namespace.com", TypeName = "InnerException")]
public partial class InnerException
{
[XmlElement(Form = XmlSchemaForm.Unqualified, ElementName = "message")]
public String Message { get; set; }
}
这是我试图阅读的服务器的回复:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><env:Body><env:Fault><faultcode>env:Server</faultcode><faultstring>internal error</faultstring><detail><ns2:InnerException xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://ns1.my.namespace.com" xmlns:ns2="http://my.namespace.com" xmlns:ns3="http://ns3.my.namespace.com"><message>internal error</message></ns2:InnerException ></detail></env:Fault></env:Body></env:Envelope>
我试图阅读它的方式如下:
using (XmlReader reader = XmlReader.Create(await response.Content.ReadAsStreamAsync()))
{
string SoapNamespace = "http://schemas.xmlsoap.org/soap/envelope/";
try
{
var serializer = new XmlSerializer(typeof(SoapFault));
reader.ReadStartElement("Envelope", SoapNamespace);
reader.ReadStartElement("Body", SoapNamespace);
var fault = serializer.Deserialize(reader) as SoapFault;
reader.ReadEndElement();
reader.ReadEndElement();
}
catch(Exception ex)
{
throw new Exception("Exception was thrown:" + ex.Message);
}
}
我尝试添加名称空间,更改XmlElement属性,但我总是以SoapFault中的Detail属性为NULL。当我将类型更改为对象时,我至少得到一个包含数据的XmlNode集。
我必须在此代码中更改什么才能在序列化上实例化正确的类?
请注意:我不幸被迫手动创建电话,不能使用自动生成的代码。
答案 0 :(得分:6)
受到How to Deserialize XML document的极大启发,我认为这应该可以解决问题。
我按如下方式生成了这个类:
这导致:

是的,它是自动生成的,但我认为这是创建一个可以反序列化的类的最简单方法。您可以这样做:
XmlDocument document = new XmlDocument();
document.Load(Server.MapPath("~/Data/reply.xml"));
System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(Envelope));
Envelope envelope = (Envelope)serializer.Deserialize(new StringReader(document.OuterXml));
正确选择了Detail
属性。在您的情况下,您需要像以前一样使用XmlReader
而不是我的new StringReader(document.OuterXml)
,并将其包装在使用块等中。
请记住,反序列化对象的某些属性名称与您在SoapFault
类中的属性名称不完全匹配(例如,它现在称为Envelope
),有些属性表示为数组而不是单个对象,但如果需要,您可以调整Xsd以适应。
