使用命名空间和多个嵌套元素反序列化 XML [英] Deserializing XML with namespace and multiple nested elements

问题描述

我正在尝试反序列化以下 xml

I am trying to deserialize the following 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>

使用这些类

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);
    }
}

但不知何故我一直收到这个错误.

but somehow I keep getting this error.

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.

What is the correct way of doing it ? The method works for deserializing without the namespace.

推荐答案

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.

The problem is that the namespace of myrootNS class is incorrect because it doesn't match the expected namespace in the XML.

[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:

Notice that the Namespace property value has a trailing /. This is my deserialize method:

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);
        }
    }
}
