使用.NET XmlSerializer进行反序列化时,请使用多个名称空间

Question

我正在尝试使用两个名称空间反序列化XML,就像这样

<records xmlns="http://www.foo.com/xml/records/1.1">
    <record xmlns="http://www.foo.com/xml/record/1.1">

有时候是旧版本

<records xmlns="http://www.foo.com/xml/records/1.1">
    <record xmlns="http://www.foo.com/xml/record/1.0">

我的Records.cs类有

[XmlRoot(ElementName = "records", Namespace = "http://www.foo.com/xml/records/1.1")]
public class Records
{
    [System.Xml.Serialization.XmlElementAttribute("record")]
    public List<Record> Records { get; set; }
}

我希望记录列表能够包含版本1.0或版本1.1记录

/// <remarks/>
[XmlRoot(IsNullable = false, ElementName = "record", Namespace = "http://www.foo.com/xml/record/1.0")]
public partial class Record
{


    /// <remarks/>

    public Record()
    {

    }
}

/// <remarks/>
[XmlRoot(IsNullable = false, ElementName = "record", Namespace = "http://www.foo.com/xml/record/1.1")]
public partial class Record11 : Record
{
    /// <remarks/>
    public Record11()
    {
    }
}

所以我假设子类化记录会起作用.

反序列化时我得到一个Reflection异常,异常将我指向XmlChoiceIdentifier属性.但是,这似乎与枚举有关.

任何人都知道如何做我想做的事情(支持反序列化同一模式的多个版本？)

谢谢.

[XmlRoot]您Record和Record11示例中的属性都将被忽略.它们只有在元素是树中的根时才有意义.你宁愿做的是:

[XmlRoot(ElementName = "records",
         Namespace = "http://www.foo.com/xml/records/1.1")]
public class Records
{
    [XmlElement(Type = typeof(Record),
                ElementName = "record",
                Namespace = "http://www.foo.com/xml/records/1.0")]
    [XmlElement(Type = typeof(Record11),
                ElementName = "record",
                Namespace = "http://www.foo.com/xml/records/1.1")]
    public List<Record> Records { get; set; }
}
