我正在尝试反序列化我从Web服务收到的SoapException消息。 我遇到以下异常:
System.InvalidOperationException was unhandled
Message="There is an error in XML document (2, 2)."
Source="System.Xml"
StackTrace:

InnerException: System.InvalidOperationException
Message="<Fault xmlns='http://idealliance.org/maildat/Specs/md091/mailxml81/mailxml'> was not expected."
Source="gn4ggxxc"
StackTrace:

如何正确地将此XML反序列化为提供的分部类错误?
以下是我如何读取XMLSerializer中的XML字符串:
XmlTextReader xr = new XmlTextReader(new StringReader(soapEx.Detail.FirstChild.InnerText));
XmlSerializer xs = new XmlSerializer(typeof(Fault));
Fault fault = xs.Deserialize(xr) as Fault;
这是soap异常的内部文本.Detail属性的FirstChild
<?xml version="1.0" encoding="UTF-8"?>
<mailxml:Fault xmlns:mailxml="http://idealliance.org/maildat/Specs/md091/mailxml81/mailxml" xmlns:mailxml_base="http://idealliance.org/maildat/Specs/md091/mailxml81/base" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://idealliance.org/maildat/Specs/md091/mailxml81/mailxml mailxml_031910.xsd http://idealliance.org/maildat/Specs/md091/mailxml81/base mailxml_base_031910.xsd">
<mailxml:FaultCode>402</mailxml:FaultCode>
<mailxml:FaultDescription>402 Not Well Formed XML</mailxml:FaultDescription>
</mailxml:Fault>
这是通过WSDL自动生成的部分类。

在RootElement上设置命名空间就可以了解
XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.Namespace = "http://namespacehere";
XmlReader xr = soapEx.Detail.FirstChild.CreateNavigator().ReadSubtree();
XmlSerializer xs = new XmlSerializer(typeof(Fault), xRoot);
Fault fault = xs.Deserialize(xr) as Fault;

首先,除非您没有其他选择,否则请勿使用new XmlTextReader()
。它自.NET 2.0以来就被弃用。
其次,您已经拥有XML - 为什么要将其转换为字符串然后再转换为XML?尝试
XmlReader xr = soapex.Detail.FirstChild.CreateNavigator().ReadSubTree();
Fault fault = xs.Deserialize(xr) as Fault;
