C#反序列化XML到对象

Question

在将某些 xml 反序列化为 C# 中的对象时出现问题。

我收到的错误是...

xmlns=''> was not expected.

我收到的用于生成我的类的 XSD 如下...

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="xml.AAAAAAA.com/commerce/apres-vente_technique/assistance" xmlns:pgp="xml.AAAAAAA.com/commerce/apres-vente_technique/assistance" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
    <xs:element name="ListeAvisRemboursements">
        <xs:annotation>
            <xs:documentation>Liste des avis de remboursements</xs:documentation>
        </xs:annotation>
        <xs:complexType>
            <xs:sequence maxOccurs="unbounded">
                <xs:element name="AvisRemboursement" type="pgp:AvisRemboursementType"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
    <xs:complexType name="AvisRemboursementType">
        <xs:annotation>
            <xs:documentation>Avis de remboursement lié à une DC</xs:documentation>
        </xs:annotation>
        <xs:sequence>

(截断)

我尝试导入的文件如下:

<?xml version="1.0" encoding="UTF-8"?>
<ListeAvisRemboursements xmlns:ast="xml.AAAAAAA.com/commerce/apres-vente_technique/assistance">
    <ast:AvisRemboursement NumeroDT="3826961" CodeRA="020545G01" NumeroDC="1">
        <ast:DateTraitement>2010-06-22</ast:DateTraitement>
        <ast:MontantDC>25.0</ast:MontantDC>
        <ast:MontantMO>0.0</ast:MontantMO>
        <ast:SommeAD>25.0</ast:SommeAD>
        <ast:MontantPR>0.0</ast:MontantPR>
        <ast:SommePR>0.0</ast:SommePR>
        <ast:FraisGestion>0.0</ast:FraisGestion>
        <ast:NombreHeuresTotalRemboursees>0</ast:NombreHeuresTotalRemboursees>
        <ast:Etat>C</ast:Etat>
        <ast:NoteCredit>319984</ast:NoteCredit>
        <ast:Imputation>030</ast:Imputation>
        <ast:ListInterventionsPR/>
        <ast:ListInterventionsMO/>
    </ast:AvisRemboursement>

我认为 发生的事情是，当 .Net 尝试反序列化 xml 时，它会命中包含“xmlns:ast”的第一行并对其进行投诉。据我了解，.Net 将尝试将属性映射到目标类中的公共(public)属性(它不会找到一个名为 xmlns 的属性。或者我处理 namespace 的方式有问题。

我的反序列化代码如下所示:

    XmlDocument _Doc = new XmlDocument();
    _Doc.Load(@"C:\inputfile.xml");

    XmlSerializer _XMLSer = new XmlSerializer(typeof(ListeAvisRemboursements));
    ListeAvisRemboursements _X = (ListeAvisRemboursements)_XMLSer.Deserialize(new StringReader(_Doc.OuterXml));

我还尝试了将命名空间管理器添加到 XML 文档的各种组合。

XmlNamespaceManager _Ns = new XmlNamespaceManager(_Doc.NameTable);
_Ns.AddNamespace("ast", "xml.AAAAAAA.com/commerce/apres-vente_technique/assistance");

我知道有一种方法可以使用它来告诉 .Net 接受哪些命名空间。

如果能在这个问题上提供一些帮助，我们将不胜感激。

没有完整的 xsd/xml，或者(或者)您的 C# 类，我们无法重现。但是从 xml 向上工作，这对我来说很好；意思是:错误不在(据我所知)您发布的代码/数据中。您能否发布一个更完整(可重现)的示例？

public class ListeAvisRemboursements
{
    private readonly List<AvisRemboursement> items = new List<AvisRemboursement>();
    [XmlElement("AvisRemboursement", Namespace = "xml.AAAAAAA.com/commerce/apres-vente_technique/assistance")]
    public List<AvisRemboursement> Items { get { return items; } }
}
public class AvisRemboursement
{
    [XmlAttribute] public string NumeroDT {get;set;}
    [XmlAttribute] public string CodeRA {get;set;}
    [XmlAttribute] public string NumeroDC {get;set;}
    public DateTime DateTraitement { get; set; }
    public decimal MontantDC { get; set; }
    public decimal MontantMO { get; set; }
    public decimal SommeAD { get; set; }
    public decimal MontantPR { get; set; }
    public decimal SommePR { get; set; }
    public decimal FraisGestion { get; set; }
    public int NombreHeuresTotalRemboursees { get; set; }
    public string Etat { get; set; }
    public string NoteCredit { get; set; }
    public string Imputation { get; set; }
}
static void Main()
{
    var ser = new XmlSerializer(typeof(ListeAvisRemboursements));
    var wrapper = (ListeAvisRemboursements)ser.Deserialize(new StringReader(xml));
    // inspect wrapper.Items etc
}

也适用于:

var ser = new XmlSerializer(typeof(ListeAvisRemboursements));
using (var reader = XmlReader.Create("inputfile.xml"))
{
    var wrapper = (ListeAvisRemboursements)ser.Deserialize(reader);
}

和:

XmlDocument _Doc = new XmlDocument();
_Doc.Load("inputfile.xml");
var ser = new XmlSerializer(typeof(ListeAvisRemboursements));
var wrapper = (ListeAvisRemboursements)ser.Deserialize(new StringReader(_Doc.OuterXml));

和

XmlDocument _Doc = new XmlDocument();
_Doc.Load("inputfile.xml");
var ser = new XmlSerializer(typeof(ListeAvisRemboursements));
var wrapper = (ListeAvisRemboursements)ser.Deserialize(new XmlNodeReader(_Doc.DocumentElement));
