使用.NET XmlSerializer的反序列化时,使用多个命名空间 [英] Use multiple namespaces when deserializing with .NET XmlSerializer
问题描述
我试图反序列化XML与两个命名空间,这样
I'm trying to deserialize XML with two namespaces, like this
<records xmlns="http://www.foo.com/xml/records/1.1">
<record xmlns="http://www.foo.com/xml/record/1.1">
有时旧版本的
and sometimes an older version
<records xmlns="http://www.foo.com/xml/records/1.1">
<record xmlns="http://www.foo.com/xml/record/1.0">
我Records.cs类有
My Records.cs class has
[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; }
}
我要记录列出要能包含一个版本1.0或1.1版记录
I want the Records list to be able to contain either a version 1.0 or version 1.1 Record
/// <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()
{
}
}
所以我认为继承记录会工作。
so I assumed subclassing the record would work.
反序列化时,我得到一个反射异常,异常点我到XmlChoiceIdentifier属性。然而,这似乎与枚举。
I get a Reflection exception when deserializing and the exception points me to the XmlChoiceIdentifier attribute. However, that seems related to enums.
任何人都知道该怎么做我想做的事情(支持反序列化同一模式的多个版本?)
Anyone know how to do what I want to do (support deserializing multiple versions of the same schema?)
感谢。
推荐答案
[XmlRoot]
属性上都录制
和 Record11
将被忽略。他们只有当元素是树中的本质的含义。什么你更需要做的是这样的:
[XmlRoot]
attributes on both Record
and Record11
in your example will be ignored. They only have meaning when element is a root in the tree. What you rather need to do is this:
[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; }
}
