问题序列化类XML和包括CDATA节 [英] Problems serializing a class to XML and including a CDATA section
问题描述
我有一个是通过Web服务序列化为XML消费类。在这一类实例的XML必须包含CDATA部分Web服务读它，但我就如何实现这一损失。
XML的需要看这样的：
< UpdateOrderStatus>
<作用> 2'; /作用>
< VALUE>
<！[CDATA [
<装运>
<页眉和GT;
< SellerID>
...
]]≥
< /价值与GT;
< / UpdateOrderStatus>
我能够生成相应的XML，除了CDATA部分。
我的阶级结构是这样的：
公共类UpdateOrderStatus
{
公众诠释行动{搞定;组; }
公共ValueInfo值{搞定;组; }
公共UpdateOrderStatus（）
{
值=新ValueInfo（）;
}
公共类ValueInfo
{
公共ShipmentInfo出货{搞定;组; }
公共ValueInfo（）
{
出货=新ShipmentInfo（）;
}
公共类ShipmentInfo
{
公共PackageListInfo PackageList {搞定;组; }
公共HeaderInfo头{搞定;组; }
公共ShipmentInfo（）
{
PackageList =新PackageListInfo（）;
=头新HeaderInfo（）;
}
....
我已经看到了一些使用建议：
[的XmlElement（节点的typeof（XmlCDataSection））]
但导致异常
我也试过
[的XmlElement（值+<！[CDATA [）]
但生成的XML是不正确的表现。
< Value_x003C__x0021__x005B_CDATA_x005B_>
....
< / Value_x003C__x0021__x005B_CDATA_x005B_>
谁能告诉我什么我做错了，或者我需要去与此？
- Edit--
使得每carlosfigueira shipmentInfo序列工作的大部分，但我得到额外？在生成的XML字符（看帖子编写使用XmlWriterSettings和XmlSerializer的是给了细节的额外字符）
XML片段
因此，我改变了写XML的方法：
公共无效中WriteXML（XmlWriter的作家）使用
{
（MemoryStream的毫秒=新的MemoryStream（））
{
XmlSerializerNamespaces NS =新XmlSerializerNamespaces（）;
ns.Add（，）;
XmlWriterSettings设置=新XmlWriterSettings（）;
settings.OmitXmlDeclaration = TRUE;
settings.Encoding =新UnicodeEncoding（大尾端：假的，byteOrderMark：假）;
settings.Indent = TRUE;使用（XmlWriter的innerWriter = XmlWriter.Create（MS，设置））
{
shipmentInfoSerializer.Serialize（innerWriter，this.Shipment，NS）
;
innerWriter.Flush（）;
writer.WriteCData（Encoding.UTF8.GetString（ms.ToArray（）））;
}
}
}
不过我没有得到一个例外：
System.InvalidOperationException：有一个错误生成XML文档。 ---> System.ArgumentException：''，十六进制
值为0x00，是一个无效字符。

的
例外被列入我以前serializeToString方法造成的。由于去掉了CDATA输出是正确的，除了间距的问题，但我也越来越应由指定的XML设置中删除一个命名空间和XML声明。输出是：
< XML版本=1.0>？

使用新的类避免了BOM的任何想法？

建议
我已经实现变化的成功 - 编辑3！以下，现在有以下Writer类和测试方法：
UpdateOrderStatus的obj =新UpdateOrderStatus（）;
obj.Action = 1;
obj.Value =新UpdateOrderStatus.ValueInfo（）;
obj.Value.Shipment =新UpdateOrderStatus.ValueInfo.ShipmentInfo（）;
obj.Value.Shipment.Header.SellerId =装运头;
obj.Value.Shipment.PackageList =新UpdateOrderStatus.ValueInfo.ShipmentInfo.PackageListInfo（）;
obj.Value.Shipment.PackageList.Package =新UpdateOrderStatus.ValueInfo.ShipmentInfo.PackageListInfo.PackageInfo（）;
obj.Value.Shipment.PackageList.Package.ShipDate = DateTime.Now;
XmlSerializerNamespaces NS =新XmlSerializerNamespaces（）;
ns.Add（，）;
XmlWriterSettings设置=新XmlWriterSettings（）;
settings.OmitXmlDeclaration = TRUE;
settings.Encoding =新的UTF8Encoding（假）;
settings.Indent = TRUE;
XmlSerializer的XS =新的XmlSerializer（typeof运算（UpdateOrderStatus））;
的MemoryStream毫秒=新的MemoryStream（）;
XmlWriter的作家= XmlWriter.Create（MS，设置）;
xs.Serialize（作家，OBJ，NS）;
Console.WriteLine（Encoding.UTF8.GetString（ms.ToArray（）））;
}
公共无效中WriteXML（XmlWriter的作家）
{
XmlSerializerNamespaces NS =新XmlSerializerNamespaces（）;
ns.Add（，）;
XmlWriterSettings设置=新XmlWriterSettings（）;
settings.OmitXmlDeclaration = TRUE;
settings.Indent = TRUE;
StringBuilder的SB =新的StringBuilder（）;
使用（XmlWriter的innerWriter = XmlWriter.Create（SB，设置））
{
shipmentInfoSerializer.Serialize（innerWriter，this.Shipment，NS）;
innerWriter.Flush（）;
writer.WriteCData（sb.ToString（））;
}
}
这将产生以下XML：
< UpdateOrderStatus>
<作用> 1 LT; /作用>
< VALUE><！[CDATA [< ShipmentInfo>
< PackageList>
<包装及GT;
<&并按ShipDate GT; 2012-07-13T14：05：36.6170802-04：00< /并按ShipDate>
<&ITEMLIST GT;
<项目>
将; ShippedQty大于0&下; / ShippedQty>
< /项目>
< / ITEMLIST>
< /包装及GT;
< / PackageList>
<页眉和GT;
< SellerId>装运头< / SellerId>
将; SONumber大于0&下; / SONumber>
< /页眉和GT;
< / ShipmentInfo>]]>< /价值与GT;
< / UpdateOrderStatus>
在回应'空间'你以后看到您的编辑，这是因为编码您使用的是（Unicode中，每个字符2个字节）。
尝试：
settings.Encoding =新Utf8Encoding（假） ;
编辑：
另外，还要注意的是格式的MemoryStream 是的不的一定是有效的UTF-8编码的字符串！您可以使用的StringBuilder 而不是的MemoryStream 以创建你内心的作家。
公共无效中WriteXML（XmlWriter的作家）
{
XmlSerializerNamespaces NS =新XmlSerializerNamespaces（）;
ns.Add（，）;
XmlWriterSettings设置=新XmlWriterSettings（）;
settings.OmitXmlDeclaration = TRUE;
settings.Indent = TRUE;
StringBuilder的SB =新的StringBuilder（）;
使用（XmlWriter的innerWriter = XmlWriter.Create（SB，设置））
{
shipmentInfoSerializer.Serialize（innerWriter，this.Shipment，NS）;
innerWriter.Flush（）;
writer.WriteCData（sb.ToString（））;
}
}
I have a class that is serialized into XML for consumption by a web service. In this classes instance the XML must include a CDATA section for the web service to read it but I am at a loss on how to implement this.
The XML needs to look like:
<UpdateOrderStatus>
<Action>2</Action>
<Value>
<![CDATA[
<Shipment>
<Header>
<SellerID>
...
]]>
</Value>
</UpdateOrderStatus>
I am able to generate the appropriate XML, except for the CDATA part.
My class structure looks like:
public class UpdateOrderStatus
{
public int Action { get; set; }
public ValueInfo Value { get; set; }
public UpdateOrderStatus()
{
Value = new ValueInfo();
}
public class ValueInfo
{
public ShipmentInfo Shipment { get; set; }
public ValueInfo()
{
Shipment = new ShipmentInfo();
}
public class ShipmentInfo
{
public PackageListInfo PackageList { get; set; }
public HeaderInfo Header { get; set; }
public ShipmentInfo()
{
PackageList = new PackageListInfo();
Header = new HeaderInfo();
}
....
I have seen some suggestions on using:
[XmlElement("node", typeof(XmlCDataSection))]
but that causes an exception
I have also tried
[XmlElement("Value" + "<![CDATA[")]
but the resulting XML is incorrect showing
<Value_x003C__x0021__x005B_CDATA_x005B_>
....
</Value_x003C__x0021__x005B_CDATA_x005B_>
Can anyone show me what I am doing wrong, or where I need to go with this?
--Edit--
making shipmentInfo serializable per carlosfigueira works for the most part, however I get extra ? characters in the resulting XML ( see post Writing an XML fragment using XmlWriterSettings and XmlSerializer is giving an extra character for details )
As such I changed the Write XML method to:
public void WriteXml(XmlWriter writer)
{
using (MemoryStream ms = new MemoryStream())
{
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");
XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
settings.Encoding = new UnicodeEncoding(bigEndian: false, byteOrderMark: false);
settings.Indent = true;
using (XmlWriter innerWriter = XmlWriter.Create(ms, settings))
{
shipmentInfoSerializer.Serialize(innerWriter, this.Shipment,ns);
innerWriter.Flush();
writer.WriteCData(Encoding.UTF8.GetString(ms.ToArray()));
}
}
}
However I am not getting an exception:
System.InvalidOperationException: There was an error generating the XML document. ---> System.ArgumentException: '.', hexadecimal
value 0x00, is an invalid character.
--Edit --
The exception was caused by the inclusion of my previous serializeToString method. Since removing that the CDATA output is correct, except for a spacing issue, but I am also getting a namespace and xml declaration that should be removed by the XML settings specified. Output is:
<?xml version="1.0"?>
<UpdateOrderStatus xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Action>1</Action>
<Value><![CDATA[< S h i p m e n t I n f o >
< P a c k a g e L i s t >
< P a c k a g e >
< S h i p D a t e > 2 0 1 2 - 0 7 - 1 3 T 1 1 : 5 8 : 5 1 . 0 9 2 5 6 1 5 - 0 4 : 0 0 < / S h i p D a t e >
< I t e m L i s t >
< I t e m >
< S h i p p e d Q t y > 0 < / S h i p p e d Q t y >
< / I t e m >
< / I t e m L i s t >
< / P a c k a g e >
< / P a c k a g e L i s t >
< H e a d e r >
< S e l l e r I d > S h i p m e n t h e a d e r < / S e l l e r I d >
< S O N u m b e r > 0 < / S O N u m b e r >
< / H e a d e r >
< / S h i p m e n t I n f o > ]]></Value>
</UpdateOrderStatus>
Any ideas of avoiding the BOM using the new class?
--Edit 3 -- SUCCESS!
I have implemented changes suggested below and now have the following writer class and test methods:
UpdateOrderStatus obj = new UpdateOrderStatus();
obj.Action = 1;
obj.Value = new UpdateOrderStatus.ValueInfo();
obj.Value.Shipment = new UpdateOrderStatus.ValueInfo.ShipmentInfo();
obj.Value.Shipment.Header.SellerId = "Shipment header";
obj.Value.Shipment.PackageList = new UpdateOrderStatus.ValueInfo.ShipmentInfo.PackageListInfo();
obj.Value.Shipment.PackageList.Package = new UpdateOrderStatus.ValueInfo.ShipmentInfo.PackageListInfo.PackageInfo();
obj.Value.Shipment.PackageList.Package.ShipDate = DateTime.Now;
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");
XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
settings.Encoding = new UTF8Encoding(false);
settings.Indent = true;
XmlSerializer xs = new XmlSerializer(typeof(UpdateOrderStatus));
MemoryStream ms = new MemoryStream();
XmlWriter writer = XmlWriter.Create(ms, settings);
xs.Serialize(writer, obj, ns);
Console.WriteLine(Encoding.UTF8.GetString(ms.ToArray()));
}
public void WriteXml(XmlWriter writer)
{
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");
XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
settings.Indent = true;
StringBuilder sb = new StringBuilder();
using (XmlWriter innerWriter = XmlWriter.Create(sb, settings))
{
shipmentInfoSerializer.Serialize(innerWriter, this.Shipment, ns);
innerWriter.Flush();
writer.WriteCData(sb.ToString());
}
}
This produces the following XML:
<UpdateOrderStatus>
<Action>1</Action>
<Value><![CDATA[<ShipmentInfo>
<PackageList>
<Package>
<ShipDate>2012-07-13T14:05:36.6170802-04:00</ShipDate>
<ItemList>
<Item>
<ShippedQty>0</ShippedQty>
</Item>
</ItemList>
</Package>
</PackageList>
<Header>
<SellerId>Shipment header</SellerId>
<SONumber>0</SONumber>
</Header>
</ShipmentInfo>]]></Value>
</UpdateOrderStatus>
In response to the 'spaces' you are seeing after your edit, it is because of the encoding you are using (Unicode, 2 bytes per character).
Try:
settings.Encoding = new Utf8Encoding(false);
EDIT:
Also, note that format of the MemoryStream is not necessarily a valid UTF-8 encoded string! You can use a StringBuilder instead of MemoryStream to create your inner writer.
public void WriteXml(XmlWriter writer)
{
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");
XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
settings.Indent = true;
StringBuilder sb = new StringBuilder();
using (XmlWriter innerWriter = XmlWriter.Create(sb, settings))
{
shipmentInfoSerializer.Serialize(innerWriter, this.Shipment,ns);
innerWriter.Flush();
writer.WriteCData(sb.ToString());
}
}
