使用命名空间和多个嵌套元素反序列化XML

Question

我试图反序列化以下的xml

<?xml version="1.0" encoding="utf-8"?>
<ns2:myroot xmlns:ns2="http://jeson.com/">
  <item>
    <name>uno</name>
    <price>1.25</price>
  </item>
  <item>
    <name>dos</name>
    <price>2.30</price>
  </item>
</ns2:myroot>

与这些课程

public class item
{
    [XmlElement(Namespace="")]
    public string name { get; set; }

    [XmlElement(Namespace = "")]
    public double price { get; set; }
}

[XmlRoot("myroot", Namespace="http://jeson.com/")]  //This was http://jeson.com, no slash at the end.
public class myrootNS
{
    [XmlElement(Namespace = "")]
    public item[] item { get; set; }
}

使用这种方法

XmlSerializer serializer = new XmlSerializer(typeof(T), "http://jeson.com/");
XmlReaderSettings settings = new XmlReaderSettings();
using (StringReader textReader = new StringReader(xml))
{
    using (XmlReader xmlReader = XmlReader.Create(textReader, settings))
    {
        return (T)serializer.Deserialize(xmlReader);
    }
}

但不知怎的,我不断收到这个错误.

System.InvalidOperationException: There is an error in XML document (2, 2). ---> 
System.InvalidOperationException: <myroot xmlns='http://jeson.com/'> was not expected.

这样做的正确方法是什么？该方法适用于没有命名空间的反序列化.

Answer 1

问题是myrootNS类的命名空间不正确,因为它与XML中的预期命名空间不匹配.

[XmlRoot("myroot", Namespace = "http://jeson.com/")]
public class myrootNS
{
    [XmlElement(Namespace = "")]
    public item[] item { get; set; }
}

请注意,Namespace属性值具有尾随/.这是我的反序列化方法:

static T Deserialize<T>(string xml)
{
    XmlSerializer serializer = new XmlSerializer(typeof(T));
    XmlReaderSettings settings = new XmlReaderSettings();
    using (StringReader textReader = new StringReader(xml))
    {
        using (XmlReader xmlReader = XmlReader.Create(textReader, settings))
        {
            return (T)serializer.Deserialize(xmlReader);
        }
    }
}
