从多个类生成XML

Question

我想使用xsd.exe工具生成的类生成XML文档。

所需的结构是这样的：

<sh:StandardBusinessDocument xmlns:eanucc="urn:ean.ucc:2" xmlns:order="urn:ean.ucc:order:2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" schemaLocation="http://www.unece.org/cefact/namespaces/StandardBusinessDocumentHeader ../Schemas/sbdh/StandardBusinessDocumentHeader.xsd urn:ean.ucc:2 ../Schemas/OrderProxy.xsd" xmlns:sh="http://www.unece.org/cefact/namespaces/StandardBusinessDocumentHeader"> 
    <sh:StandardBusinessDocumentHeader> 
    <sh:HeaderVersion>2.2</sh:HeaderVersion>  
    </sh:StandardBusinessDocumentHeader> 
    <eanucc:message> 
    <entityIdentification> 
     <uniqueCreatorIdentification>2222</uniqueCreatorIdentification> 
    </entityIdentification> 
    </eanucc:message> 
</sh:StandardBusinessDocument> 

但我只能够做到这一点：

<sh:StandardBusinessDocument xmlns:eanucc="urn:ean.ucc:2" xmlns:order="urn:ean.ucc:order:2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" schemaLocation="http://www.unece.org/cefact/namespaces/StandardBusinessDocumentHeader ../Schemas/sbdh/StandardBusinessDocumentHeader.xsd urn:ean.ucc:2 ../Schemas/OrderProxy.xsd" xmlns:sh="http://www.unece.org/cefact/namespaces/StandardBusinessDocumentHeader"> 
    <sh:StandardBusinessDocumentHeader> 
    <sh:HeaderVersion>2.2</sh:HeaderVersion>  
    </sh:StandardBusinessDocumentHeader> 
    <sh:message> 
    <entityIdentification> 
     <uniqueCreatorIdentification>2222</uniqueCreatorIdentification> 
    </entityIdentification> 
    </sh:message> 
</sh:StandardBusinessDocument> 

如何创建根节点的孩子的不同节点的前缀？在我生成的类中，我使用XmlTypeAttribute和XmlRootAttribute添加了名称空间，但第二个子属性将忽略它们。我班有属性如下：

为什么第二个孩子（StandardBusinessDocumentMessage）装修被忽略任何想法？

Answer 1

首先，指定在检索messageField属性的映射的命名空间（I假设有一个）：

[XmlElement(Namespace = "urn:ean.ucc:2")] 
public StandardBusinessDocumentMessage Message { get; set; } 

然后，序列化对象时，创建XmlSerializerNamespaces类的实例，添加前缀和名称空间，并将其用于以XmlSerializerNamespaces对象作为参数的Serialize（）重载：

XmlSerializerNamespaces ns = new XmlSerializerNamespaces(); 
    ns.Add("eanucc", "urn:ean.ucc:2"); 
    ns.Add("sh", "http://www.unece.org/cefact/namespaces/StandardBusinessDocumentHeader"); 
    XmlSerializer xs = new XmlSerializer(typeof(StandardBusinessDocument)); 
    xs.Serialize(someStream, someInstance, ns);
