反序列化XML命名空间没有,但一类期待的命名空间 [英] Deserialize XML without namespaces but in a class expecting namespaces
问题描述
重复:?结果
序列化对象
不一样的。我想在其他方式:反序列化

我有一个C#类波纹管:
I have a C# class as bellow:
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.42")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://www.portalfiscal.inf.br/nfe")]
[System.Xml.Serialization.XmlRootAttribute("NFe", Namespace = "http://www.portalfiscal.inf.br/nfe", IsNullable = false)]
public partial class TNFe
{
private TNFeInfNFe infNFeField;
private SignatureType signatureField;
/// <remarks/>
public TNFeInfNFe infNFe
{ ...
我使用这个类来序列按用户要求/反序列化的XML文件。
,但我有一个问题:命名空间定义了这个软件的新版本中添加。
中的XML仍然是一样的,只是添加命名空间定义。
I use this class to serialize/deserialize XML files by user request. But I've got a problem: namespaces definition were added on the new version of this software. The XML is still the same, only adding namespaces definition.
例如,去年的版本...
Eg., last version...
<?xml version="1.0" encoding="utf-8" ?>
<NFe>
<infNFe version="1.10">
...
和新版本...
<?xml version="1.0" encoding="utf-8" ?>
<NFe xmlns="http://www.portalfiscal.inf.br/nfe">
<infNFe version="2.10">
...
我需要加载使用和不使用这些命名空间的XML文件。
我有很多嵌套类和每个它有自己的命名空间定义。
I need to load XML files with and without these namespaces. I have a lot of nested classes and each of it has its own namespaces definition.
我想用相同的类为XML ,有和没有命名空间。
我试图创建一个XmlTextReader并覆盖的namespaceURI方法,但我仍收到没有太多的信息异常。我认为.NET引擎试图迫使对XML类的命名空间定义。
I tried to create an XmlTextReader and overwrite the NamespaceURI method, but I still receives an exception with no much info. I think .NET engine is trying to force the class namespace definition against the XML.
推荐答案
我已经碰到了类似的挑战,代理类。对于我不会进入的原因,我需要手动序列化类使用Web服务器上的XmlSerializer和反序列化的客户端。我没能在网上找到一个完美的解决方案,所以我只是通过从Visual Studio中后,手动我自动生成它的代理类删除XmlTypeAttribute回避的问题。
I had run into a similar challenge with a proxy class. For reasons that I won't go into, I needed to serialize the class manually using the XmlSerializer on web server and deserialize on client. I was not able to find an elegant solution online, so I just avoided the issue by removing the XmlTypeAttribute from the proxy class manually after I auto-generated it in Visual Studio.
我一直回来看看是否有一种方式来获得命名空间来锻炼。这是我如何得到它,而不需要修改自动生成的类的工作。最后我用一个XmlTextReader返回匹配属性名称节点所需的命名空间。还有改进的余地,但我希望它可以帮助别人。
I kept coming back to see if there was a way to get the namespace to workout. Here is how I got it working without the need to modify the auto-generated classes. I ended up using an XmlTextReader to return the desired namespace on nodes matching a property name. There is room for improvement, but i hope it helps someone.
class Program
{
static void Main(string[] args)
{
//create list to serialize
Person personA = new Person() { Name = "Bob", Age = 10, StartDate = DateTime.Parse("1/1/1960"), Money = 123456m };
List<Person> listA = new List<Person>();
for (int i = 0; i < 10; i++)
{
listA.Add(personA);
}
//serialize list to file
XmlSerializer serializer = new XmlSerializer(typeof(List<Person>));
XmlTextWriter writer = new XmlTextWriter("Test.xml", Encoding.UTF8);
serializer.Serialize(writer, listA);
writer.Close();
//deserialize list from file
serializer = new XmlSerializer(typeof(List<ProxysNamespace.Person>));
List<ProxysNamespace.Person> listB;
using (FileStream file = new FileStream("Test.xml", FileMode.Open))
{
//configure proxy reader
XmlSoapProxyReader reader = new XmlSoapProxyReader(file);
reader.ProxyNamespace = "http://myappns.com/"; //the namespace of the XmlTypeAttribute
reader.ProxyType = typeof(ProxysNamespace.Person); //the type with the XmlTypeAttribute
//deserialize
listB = (List<ProxysNamespace.Person>)serializer.Deserialize(reader);
}
//display list
foreach (ProxysNamespace.Person p in listB)
{
Console.WriteLine(p.ToString());
}
Console.ReadLine();
}
}
public class Person
{
public string Name { get; set; }
public int Age { get; set; }
public DateTime StartDate { get; set; }
public decimal Money { get; set; }
}
namespace ProxysNamespace
{
[XmlTypeAttribute(Namespace = "http://myappns.com/")]
public class Person
{
public string Name { get; set; }
public int Age { get; set; }
public DateTime Birthday { get; set; }
public decimal Money { get; set; }
public override string ToString()
{
return string.Format("{0}:{1},{2:d}:{3:c2}", Name, Age, Birthday, Money);
}
}
}
public class XmlSoapProxyReader : XmlTextReader
{
List<object> propNames;
public XmlSoapProxyReader(Stream input)
: base(input)
{
propNames = new List<object>();
}
public string ProxyNamespace { get; set; }
private Type proxyType;
public Type ProxyType
{
get { return proxyType; }
set
{
proxyType = value;
PropertyInfo[] properties = proxyType.GetProperties();
foreach (PropertyInfo p in properties)
{
propNames.Add(p.Name);
}
}
}
public override string NamespaceURI
{
get
{
object localname = LocalName;
if (propNames.Contains(localname))
return ProxyNamespace;
else
return string.Empty;
}
}
}
