具有属性的嵌套列表的反序列化

Question

我目前正试图在C#中反序列化以下XML文件。

问题是，应该包含订单位置的第二个list TraceLinkOrder没有被正确反序列化。

<?xml version="1.0" encoding="UTF-8"?>
<tli:AddTracelinkOrders xmlns:tli="urn:microsoft-dynamics-schemas/codeunit/CarismaIntegration" xmlns:x50="urn:microsoft-dynamics-nav/xmlports/x50020">
 <tli:carismaOrders>
  <x50:TracelinkOrder DocType="0" Annulation="false" TROrderType="1" Department="08">
   <x50:TracelinkOrderLine NetValue="42.00" AccountNo="100206" LineNo="10000"/>
   <x50:TracelinkOrderLine NetValue="259.17" AccountNo="100306" LineNo="20000"/>
   <x50:TracelinkOrderLine NetValue="385.80" AccountNo="100406" LineNo="30000"/>
  </x50:TracelinkOrder>
  <x50:TracelinkOrder DocType="1" Annulation="false" TROrderType="1" Department="08">
   <x50:TracelinkOrderLine NetValue="2.10" AccountNo="100206" LineNo="10000"/>
   <x50:TracelinkOrderLine NetValue="25.92" AccountNo="100306" LineNo="20000"/>
  </x50:TracelinkOrder>
 </tli:carismaOrders>
</tli:AddTracelinkOrders>

父类

[XmlRoot("AddTracelinkOrders", Namespace = "urn:microsoft-dynamics-schemas/codeunit/CarismaIntegration")]
public class TraceLinkOrders
{
    [XmlArray("carismaOrders", Namespace = "urn:microsoft-dynamics-schemas/codeunit/CarismaIntegration")]
    [XmlArrayItem("TracelinkOrder", Namespace = "urn:microsoft-dynamics-nav/xmlports/x50020")]
    public List<TraceLinkOrder> CarismaOrders { get; set; }
}

订单

[XmlRoot("TracelinkOrder")]
public class TraceLinkOrder
{
    [XmlAttribute()]
    public Int16 DocType { get; set; }

    [XmlAttribute()]
    public Boolean Annulation { get; set; }

    [XmlAttribute()]
    public Int16 TROrderType { get; set; }

    [XmlAttribute()]
    public Int16 Department { get; set; }
}

订购线

[XmlRoot("TracelinkOrderLine", Namespace = "urn:microsoft-dynamics-nav/xmlports/x50020")]
public class TraceLinkOrderLine
{
    [XmlAttribute()]
    public Decimal NetValue { get; set; }

    [XmlAttribute()]
    public String AccountNo { get; set; }

    [XmlAttribute()]
    public String LineNo { get; set; }
}

order类应该包含一个订单行列表。

我尝试向order类添加一个属性，如下所示：

[XmlArrayItem("TracelinkOrderLine", Namespace = "urn:microsoft-dynamics-nav/xmlports/x50020")]
public List<TraceLinkOrderLine> OrderLines { get; set; }

不幸的是，这个列表总是空的。

我的另一个想法是让TraceLinkOrder扩展List<TraceLinkOrderLine>，但这也不起作用。

[XmlRoot("TracelinkOrder")]
public class TraceLinkOrder : List<TraceLinkOrderLine>

当我这样做时，CarismaOrders列表是空的。

如何在仍然能够访问元素TraceLinkOrder和TraceLinkOrderLine的所有属性的情况下反序列化这个XML文件？

Answer 1

正如jdweng在我的问题的注释中所指出的，诀窍是使用XmlElement属性而不是XmlArrayItem。这将告诉C#接受该名称的所有元素，并与它们一起形成一个列表。

TraceLinkOrder类的最终代码如下所示：

[XmlRoot("TracelinkOrder")]
public class TraceLinkOrder
{
    [XmlAttribute()]
    public Int16 DocType { get; set; }

    [XmlAttribute()]
    public Boolean Annulation { get; set; }

    [XmlAttribute()]
    public Int16 TROrderType { get; set; }

    [XmlAttribute()]
    public Int16 Department { get; set; }

    [XmlElement("TracelinkOrderLine")]
    public List<TraceLinkOrderLine> OrderLines { get; set; }
}
