從多個類生成XML

Question

我想使用xsd.exe工具生成的類生成XML文檔。

所需的結構是這樣的：

<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> 

但我只能夠做到這一點：

<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> 

如何創建根節點的孩子的不同節點的前綴？在我生成的類中，我使用XmlTypeAttribute和XmlRootAttribute添加了名稱空間，但第二個子屬性將忽略它們。我班有屬性如下：

爲什麼第二個孩子（StandardBusinessDocumentMessage）裝修被忽略任何想法？

Answer 1

首先，指定在檢索messageField屬性的映射的命名空間（I假設有一個）：

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

然後，序列化對象時，創建XmlSerializerNamespaces類的實例，添加前綴和名稱空間，並將其用於以XmlSerializerNamespaces對象作爲參數的Serialize（）重載：

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);
