xmlserializernamespaces將命名空間添加到特定元素

Question

我有一個對象，我想序列化它。我想將名稱空間添加到xml文檔的特定元素。我從1個默認的xml創建了幾個.xsd文件。我使用XmlSerializer。

命名空間應該在中描述。這就是我想要的：

<env:root 
    xmls:env ="httpenv" 
    xmlns:sos="httpsos"> 
    <env:body> 
    <sos:element 
     xmlns:abc="" <--------------my namespaces are located in <sos:element 
     ... 

如果我使用類似

XmlSerializerNamespaces ns = new XmlSerializerNamespaces(); 
ns.Add("abc", "httpabc"); 
ns.add.... 
StringWriter stringWriter = new StringWriter(); 
serializer.Serialize(stringWriter, ObjectToSerialize, ns); 

我會得到下面的

<env:root 
    xmls:env ="httpenv" 
    xmlns:sos="httpsos" 
    xmlns:abc="" <-------------I do not want it here; I want it in <sos:element 
    <env:body> 
    <sos:element> 
     ... 

是否有指定的方式（以哪個元素）我想要聲明我的名稱空間還是全部在根元素中聲明？

從XML的角度來看，定義XML名稱空間的位置並不重要。如果您需要在特定位置使用XML名稱空間聲明，那麼解析XML的組件可能有問題。

好了，反正這是我想出了：

using System; 
using System.IO; 
using System.Xml; 
using System.Xml.Serialization; 

namespace XMLNamespaceChangeSerialization 
{ 
    internal class Program 
    { 
     private static void Main(string[] args) 
     { 
      var serialize = Serialize(); 
      Console.WriteLine(serialize); 
      Console.ReadLine(); 
     } 

     private static string Serialize() 
     { 
      var ns = new XmlSerializerNamespaces(); 
      ns.Add("env", "httpenv"); 
      // Don't add it here, otherwise it will be defined at the root element 
      // ns.Add("sos", "httpsos"); 
      var stringWriter = new StringWriter(); 
      var serializer = new XmlSerializer(typeof (RootClass), "httpenv"); 
      serializer.Serialize(stringWriter, new RootClass(), ns); 
      return stringWriter.ToString(); 
     } 
    } 


    [Serializable] 
    [XmlRoot(ElementName = "root")] 
    public class RootClass 
    { 
     [XmlElement(ElementName = "body", Namespace = "httpenv")] 
     public BodyClass body = new BodyClass(); 
    } 

    [Serializable] 
    public class BodyClass 
    { 
     [XmlElement(ElementName = "element", Namespace = "httpsos")] 
     public SOSClass element = new SOSClass(); 
    } 

    [Serializable] 
    public class SOSClass 
    { 
     // This will be used by XML serializer to determine the namespaces 
     [XmlNamespaceDeclarations] 
     public XmlSerializerNamespaces xmlns = new XmlSerializerNamespaces(
        new[] { new XmlQualifiedName("sos", "httpsos"), }); 
    } 
}
