【问题描述】:
我在 xml 序列化方面遇到了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:
目前看来
<?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>
但它应该看起来像
<?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>
额外的命名空间 (xmlns:xsi) 和 xsi:schemaLocation / 类型属性应添加到结果中。
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);
它工作得非常好 - 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。
由于是自动生成的,用属性来装饰类是不容易的——我猜?
感谢您的任何提示! (修改了一些信息)
