DataContractSerializer-不反序列化子列表-List <t>

Question

我正在尝试使用DataContractSerializer反序列化以下XML。

<?xml version="1.0" encoding="utf-8"?>
<order>
  <header>
    <cust>1</cust>
    <bill>2</bill>
    <ship>3</ship>
    <nbr>123456</nbr>
  </header>
  <details>
    <detail>
      <nbr>123456</nbr>
      <part>1227</part>
      <qty>2</qty>
    </detail>
  </details>
</order>

我很难反序列化始终为<detail></detail>的子null段。我的课程结构如下：

[DataContract(Name = "order", Namespace ="")]
public class Order
{
    [DataMember(Name = "header", Order = 0)]
    public Head head { get; set; }
    [DataMember(Name = "details", Order = 1)]
    public Details details { get; set; }

    public Order()
    {
    }
}

[DataContract(Name = "header", Namespace ="")]
public class Head
{
    [DataMember(Name = "cust", Order = 0)]
    public string customerNbr { get; set; }
    [DataMember(Name = "bill", Order = 1)]
    public string billNbr { get; set; }
    [DataMember(Name = "ship", Order = 2)]
    public string shipmentNbr { get; set; }
    [DataMember(Name = "nbr", Order = 3)]
    public string orderNbr { get; set; }

    public Head()
    {

    }
}

[DataContract(Name = "details")]
public class Details
{
    [DataMember(Name = "detail", Order = 0)]
    public List<Detail> DetailList { get; set; }

    public Details()
    {
        this.DetailList = new List<Detail>();
    }
}

[DataContract(Name = "detail")]
public class Detail
{
    [DataMember(Name = "nbr", Order = 0)]
    public string orderNbr { get; set; }
    [DataMember(Name = "part", Order = 1)]
    public string partNbr { get; set; }
    [DataMember(Name = "qty", Order = 2)]
    public decimal orderQty { get; set; }

    public Detail()
    {

    }
}

在我的主程序中，我正在阅读XML文档，并使用以下内容对其进行反序列化：

XDocument readDoc = XDocument.Load(fileName);
Order createOrder = null;
DataContractSerializer ser = new DataContractSerializer(typeof(Order));
createOrder = (Order)ser.ReadObject(readDoc.CreateReader());

如何使明细段正确反序列化？

Answer 1

问题在于您的数据协定类不同于实际xml结构所需的类。

您可以通过对模型进行少量修改来解决此问题。

设置Detail类的命名空间以匹配其他类中的命名空间，即：空白值。

[DataContract(Name = "detail", Namespace = "")]
public class Detail
{
    //same stuff here...
}

使您的Details类成为数据合同的集合。

[CollectionDataContract(Name = "details", Namespace = "")]
public class Details : Collection<Detail> { }

您可以检查this以获得有关收集和数据合同序列化的更多详细信息。

希望这会有所帮助！
