c# - 使用命名空间和多个嵌套元素反序列化 XML

Question

我正在尝试反序列化以下 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>

用这些类

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; }
}

使用这个方法

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);
    }
}

但不知何故我不断收到此错误。

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

正确的做法是什么？该方法适用于没有命名空间的反序列化。

问题是 myrootNS 类的命名空间不正确，因为它与 XML 中预期的命名空间不匹配。

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

请注意，Namespace 属性值有一个尾随 /。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);
        }
    }
}
