反序列化相对路径 XML [英] Deserializing relative path XML

问题描述

在 C# 中，我想反序列化一些相对位置很重要的 Xml.以下 XML 来自名为 Onix 的书籍标准:

In C# I would like to deserialize some Xml where the relative location is important. The following Xml is from a book standard called Onix:

<Stock>
  <OnHand>1</OnHand>
  <Proximity>xx</Proximity>
  <Reserved>2</Reserved>
  <Proximity>yy</Proximity>
  <OnOrder>3</OnOrder>
  <Proximity>zz</Proximity>
  <Cbo>4</Cbo>
  <Proximity>zz</Proximity>
</Stock>

如您所见，每 2 行都称为接近度".这些字段与上面的字段一致.

As you can see every 2nd line is called "Proximity". These fields goes with the field above.

如果所有字段都是必填的，那就没问题了，代码看起来像这样:

If all fields were mandatory then it would be no problem, and the code would look like this:

[XmlElement("OnHand", Order = 0)]public int OnHand { get; set; }
[XmlElement("Proximity", Order = 1)] public string OnHandProximity { get; set; }

[XmlElement("Reserved", Order = 2)] public int Reserved { get; set; }
[XmlElement("Proximity", Order = 3)] public string ReservedProximity { get; set; }

[XmlElement("OnOrder", Order = 4)] public int OnOrder { get; set; }
[XmlElement("Proximity", Order = 5)] public string OnOrderProximity { get; set; }

[XmlElement("CBO", Order = 6)] public int Cbo { get; set; }
[XmlElement("Proximity", Order = 7)] public string CboProximity { get; set; }

但是4个邻近字段与之前的字段紧密绑定，每对字段都不是强制性的.例如.您可以获得缺少前两行的 xml.

But the 4 proximity fields are tightly bound to the field before, and each pair of fields are not mandatory. E.g. you can get xml where the first 2 lines are missing.

是否有针对此类问题的属性?

Are there any Attributes intended for for these kinds of problems?

推荐答案

您正在使用 Order 属性.
将 int 标记为 int? 并将所有字段标记为 Nullable:

You were on your way with the Order attributes.
Mark the ints as int? and all fields as Nullable:

    [XmlElement("OnHand", Order = 0, IsNullable = true)]
    public int? OnHand { get; set; }

    [XmlElement("Proximity", Order = 1, IsNullable = true)]
    public string OnHandProximity { get; set; }

XmlSerializer 应该能够处理这个问题.

XmlSerializer should be able to deal with this.
