我对xml序列化有一个非常讨厌的问题 - 我需要在生成的xml文件中添加一些特殊信息:
目前,它看起来像
<?xml version="1.0" encoding="iso-8859-1"?>
<ORDER_LIST>
<ORDER version="1.0" xmlns="http://www.opentrans.org/XMLSchema/1.0">... shortened ...</ORDER>
<ORDER version="1.0" xmlns="http://www.opentrans.org/XMLSchema/1.0">... shortened ...</ORDER>
<ORDER version="1.0" xmlns="http://www.opentrans.org/XMLSchema/1.0">... shortened ...</ORDER>
</ORDER_LIST>
但它看起来应该是
<?xml version="1.0" encoding="iso-8859-1"?>
<ORDER_LIST>
<ORDER xmlns="http://www.opentrans.org/XMLSchema/1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opentrans.org/XMLSchema/1.0 openTRANS_ORDER_1_0_all_in_one.xsd" version="1.0" type="standard">... shortened ...</ORDER>
<ORDER xmlns="http://www.opentrans.org/XMLSchema/1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opentrans.org/XMLSchema/1.0 openTRANS_ORDER_1_0_all_in_one.xsd" version="1.0" type="standard">... shortened ...</ORDER>
<ORDER xmlns="http://www.opentrans.org/XMLSchema/1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opentrans.org/XMLSchema/1.0 openTRANS_ORDER_1_0_all_in_one.xsd" version="1.0" type="standard">... shortened ...</ORDER>
</ORDER_LIST>
应将额外的命名空间(xmlns:xsi)和xsi:schemaLocation / type属性添加到结果中。
其实我的代码是:
[XmlTypeAttribute(Namespace="http://www.opentrans.org/XMLSchema/1.0")]
public class OrderContainer
{
[XmlElementAttribute("ORDER")]
public List<ORDER> orderList;
}
---- snip ----
string xmlString;
XmlWriterSettings settings = new XmlWriterSettings()
{
Encoding = Encoding.GetEncoding("ISO-8859-1"),
Indent = true,
IndentChars = "\t",
NewLineChars = Environment.NewLine,
ConformanceLevel = ConformanceLevel.Document,
};
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");
var testOrder = new ORDER();
var orderContainer = new OrderContainer();
orderContainer.orderList = new List<ORDER>();
orderContainer.orderList.Add(testOrder);
XmlSerializer serializer = new XmlSerializer(typeof(List<ORDER>), new XmlRootAttribute("ORDER_LIST"));
using (MemoryStream ms = new MemoryStream())
{
using (XmlWriter writer = XmlTextWriter.Create(ms, settings))
serializer.Serialize(writer, orderList, ns);
xmlString = Encoding.ASCII.GetString(ms.ToArray());
}
Console.WriteLine(xmlString);
它的工作原理非常好 - 除了ORDER元素上的命名空间和属性 背景信息:ORDER类是从openTrans定义(opentrans_order_1_0_all_in_one.xsd)创建的 它已使用Xsd2Code(Xsd2Code)翻译成C#类 由于自动生成,使用属性装饰类是不容易的 - 我猜?

我知道回答这个问题的时间有点迟了,但我仍在回答,以防万一有需要的人偶然发现这个问题。
我要添加使用此类所需的命名空间:System.Xml.Serialization。 XmlSerializerNamespaces,我在问题代码中看到它已被定义。
以下是我在处理xCBL Xml架构时用于添加命名空间的语法:
[XmlNamespaceDeclarations]
public XmlSerializerNamespaces xmlns; //Defined as the Field of the class you want to serialize
//Defined in the Constructor
xmlns = new XmlSerializerNamespaces();
xmlns.Add("core", "rrn:org.xcbl:schemas/xcbl/v4_0/core/core.xsd");
这将在生成的Xml中添加命名空间,如下所示:
xmlns:core="rrn:org.xcbl:schemas/xcbl/v4_0/core/core.xsd"

它应该是什么样的:
<?xml version="1.0" encoding="iso-8859-1"?>
<ORDER_LIST xmlns:trans="http://www.opentrans.org/XMLSchema/1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opentrans.org/XMLSchema/1.0 http://www.opentrans.org/XMLSchema/1.0 openTRANS_ORDER_1_0_all_in_one.xsd" version="1.0" >
<trans:ORDER type="standard" >... shortened ...</ORDER>
<trans:ORDER type="standard" >... shortened ...</ORDER>
<trans:ORDER type="standard" >... shortened ...</ORDER>
</ORDER_LIST>
我不熟悉xsd2code,但如果你是手动编码,你需要放置属性。
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://www.opentrans.org/XMLSchema/1.0")]
[System.Xml.Serialization.XmlElementAttribute("Order")]
public class Order() {
String Type
}
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://www.opentrans.org/XMLSchema/1.0")]
[System.Xml.Serialization.XmlRootAttribute("OrderList", Namespace="http://www.opentrans.org/XMLSchema/1.0", IsNullable=false)]
public class OrderList() {
List<Orders>
}

试试这个。它是一个创建或读取opentrans文档的库! http://opentrans.wordpress.com/
