与XmlSerializer的多个命名空间 [英] Multiple namespaces with XmlSerializer

问题描述

这是该方案：

我有嵌套类，需要在一个XML文档然后串行化

  [XmlRoot（命名空间=htt​​p://www.foo.bar/myschema）
公共类根
{
    [XmlAttribute]
    公共字符串版本{获得;组; }

    [的XmlElement]
    公共孩童{获得;组; }

    ...
}

[XmlRoot（命名空间=htt​​p://www.foo.bar/myschema）
公共类子
{
    [的XmlElement]
    公众诠释elemA {获得;组; }

    [的XmlElement]
    公共字符串elemB {获得;组; }

    ...
}
 

我已经创建了一个基于在另一个例子的方法来消除额外的命名空间，并设置一个自定义的：

 公共静态无效的保存＆LT; T＆GT;（这件T型，字符串路径）
{
    System.Xml.Serialization.XmlSerializer XS =
        新System.Xml.Serialization.XmlSerializer（type.GetType（））;

    System.Xml.Serialization.XmlSerializerNamespaces NS =
        新System.Xml.Serialization.XmlSerializerNamespaces（）;
    ns.Add（，http://www.foo.bar/myschema）;

    使用（XmlWriter的文件= XmlWriter.Create（路径））
    {
        xs.Serialize（文件类型，NS）;
    }
}
 

和我得到这个code的结果是：

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT;根的xmlns =htt​​p://www.foo.bar/myschema版本=2.00＆GT;
    ＆LT;孩子＆GT;
        ＆其中; elemA→1＆其中; / elemA＆GT;
        ...
    ＆LT; /儿童＆GT;
＆LT; /根＆GT;
 

但预计这样的：

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT;根的xmlns =htt​​p://www.foo.bar/myschema版本=2.00＆GT;
    ＆LT;孩子的xmlns =htt​​p://www.foo.bar/myschema＆GT;
        ＆其中; elemA→1＆其中; / elemA＆GT;
        ...
    ＆LT; /儿童＆GT;
＆LT; /根＆GT;
 

我们必须设定自定义命名空间声明在这两个标签。这可能吗？

编辑：

下面是一个真实的例子：

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT; enviNFe的xmlns =htt​​p://www.portalfiscal.inf.br/nfeversao =1.01＆GT;
    ＆LT; idLote＆GT; 200602220000001＆LT; / idLote＆GT;
    ＆LT;非正规教育的xmlns =htt​​p://www.portalfiscal.inf.br/nfe＆GT;
        ＆所述; infNFe标识=NFe31060243816719000108550000000010001234567890versao =1.01＆GT;
        ...
        ＆LT;签名的xmlns =htt​​p://www.w3.org/2000/09/xmldsig#＆GT;
        ...
    ＆LT; / NFE＆GT;

解决方案

从一个XML来看你的例子是相同的，所以第一个是完全正常的。如果你必须使用第二个，有一个与我们的XML的理解或处理管道的一个严重问题。

This is the scenario:

I have nested classes and need to serialize then in an xml document

[XmlRoot(Namespace="http://www.foo.bar/myschema")]
public class root 
{
    [XmlAttribute]
    public string version { get; set; }

    [XmlElement]
    public child child { get; set; }

    ...
}

[XmlRoot(Namespace="http://www.foo.bar/myschema")]
public class child
{
    [XmlElement]
    public int elemA { get; set; }

    [XmlElement]
    public string elemB { get; set; }

    ...
}

I have created an method based in another example to remove additional namespaces and set a custom one:

public static void Save<T>(this T type, string path)
{
    System.Xml.Serialization.XmlSerializer xs = 
        new System.Xml.Serialization.XmlSerializer(type.GetType());

    System.Xml.Serialization.XmlSerializerNamespaces ns = 
        new System.Xml.Serialization.XmlSerializerNamespaces();
    ns.Add("", "http://www.foo.bar/myschema");

    using(XmlWriter file = XmlWriter.Create(path))
    {
        xs.Serialize(file, type, ns);
    }
}

And I get this code as result:

<?xml version="1.0" encoding="utf-8"?>
<root xmlns="http://www.foo.bar/myschema" version="2.00">
    <child>
        <elemA>1</elemA>
        ...
    </child>
</root>

But expected this:

<?xml version="1.0" encoding="utf-8"?>
<root xmlns="http://www.foo.bar/myschema" version="2.00">
    <child xmlns="http://www.foo.bar/myschema">
        <elemA>1</elemA>
        ...
    </child>
</root>

We must set the custom namespace declaration in both tags. Is this possible?

Edit:

Here is a real-world example:

<?xml version="1.0" encoding="UTF-8"?>
<enviNFe xmlns="http://www.portalfiscal.inf.br/nfe" versao="1.01">
    <idLote>200602220000001</idLote>
    <NFe xmlns="http://www.portalfiscal.inf.br/nfe">
        <infNFe Id="NFe31060243816719000108550000000010001234567890" versao="1.01">
        ...
        <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
        ...
    </NFe>
    <NFe xmlns="http://www.portalfiscal.inf.br/nfe">
        <infNFe Id="NFe31060243816719000108550000000010011234567900" versao="1.01">
        ...
        <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
        ...
    </NFe>
    <NFe xmlns="http://www.portalfiscal.inf.br/nfe">
        <infNFe Id="NFe31060243816719000108550000000010021234567916" versao="1.01">
        ...
        <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
        ...
    </NFe>
</enviNFe>

解决方案

From an XML point of view your examples are identical, so the first one is perfectly fine. If you have to use the second one, there is a serious problem with our XML understanding or your processing pipeline.
