  1. POC# Deserialization problem
    text
    copied!<p>I have the following class:</p> <pre><code>/// &lt;remarks/&gt; [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.1")] [System.SerializableAttribute()] [System.Diagnostics.DebuggerStepThroughAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] [System.Xml.Serialization.XmlTypeAttribute(Namespace="urn:eu.emsa.ssn")] public partial class SSN_ReceiptType { private Header1Type headerField; /// &lt;remarks/&gt; [System.Xml.Serialization.XmlElementAttribute(Order=0)] public Header1Type Header { get { return this.headerField; } set { this.headerField = value; } } } </code></pre> <p>And the following XML:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&gt; &lt;SSN_Receipt xmlns="urn:eu.emsa.ssn"&gt; &lt;Header StatusMessage="SomethingSomething" StatusCode="Blabla" SSNRefId="N/A" MSRefId="2674762" Version="2.0" To="NCANOHAU1" SentAt="2010-11-12T14:48:44Z" From="SSN"/&gt; &lt;/SSN_Receipt&gt; </code></pre> <p>And I use this typed method to deserialize (by calling Deserialize&lt;SSN_ReceiptType&gt;(xmlGoesHere)):</p> <pre><code> /// &lt;summary&gt; /// Deserialize xml string to object of type T /// &lt;/summary&gt; /// &lt;typeparam name="T"&gt;&lt;/typeparam&gt; /// &lt;param name="xml"&gt;&lt;/param&gt; /// &lt;returns&gt;&lt;/returns&gt; public static T Deserialize&lt;T&gt;(string xml) { try { // Create serializer var xs = new XmlSerializer(typeof(T)); // Deserialize T t = (T)xs.Deserialize(new StringReader(xml)); return t; } catch (Exception e) { log.Error(string.Format("Unable to deserialize XML: {0}", xml), e); return default(T); } } </code></pre> <p>Now here's the kicker. This used to work. But recently we received a new version of the XSD used to generate the classes, and after generating the new code (which is unchanged for this class, and seen above) I receive the following exception when trying to deserialize:</p> <blockquote> <p>System.SystemException: "There is an error in XML document (1, 57)"</p> </blockquote> <p>And furthermore:</p> <blockquote> <p>System.InnerException: &lt;SSN_Receipt xmlns='urn:eu.emsa.ssn'&gt; was not expected.</p> </blockquote> <p>What the hell? :S I tried adding an XmlRootAttribute specifying "SSN_Receipt", that did not help one bit. Anyone know what's going on?</p> <p>Update: relevant sections from the XSD:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ssn="urn:eu.emsa.ssn" attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="urn:eu.emsa.ssn"&gt; [...] &lt;xsd:element name="SSN_Receipt" type="ssn:SSN_ReceiptType"/&gt; [...] &lt;xsd:complexType name="SSN_ReceiptType"&gt; &lt;xsd:annotation&gt; &lt;xsd:documentation xml:lang="en"/&gt; &lt;/xsd:annotation&gt; &lt;xsd:sequence&gt; &lt;xsd:element name="Header" type="ssn:Header1Type"/&gt; &lt;/xsd:sequence&gt; &lt;/xsd:complexType&gt; </code></pre>
