我正在使用XmlSerializer创建一个用于ebay大型商家服务的xml文档。
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<BulkDataExchangeRequests xmlns="urn:ebay:apis:eBLBaseComponents">
<Header>
<SiteID>0</SiteID>
<Version>775</Version>
</Header>
<AddFixedPriceItemRequest xmlns="urn:ebay:apis:eBLBaseComponents">
<Version>775</Version>
<Item>
<AutoPay>false</AutoPay>
<BuyerProtection>ItemIneligible</BuyerProtection>
<BuyItNowPrice currencyID="USD">0.0</BuyItNowPrice>
<Country>US</Country>
<Currency>USD</Currency>
<Description>test</Description>
<GiftIcon>0</GiftIcon>
</Item>
</AddFixedPriceItemRequest>
</BulkDataExchangeRequests>
我遇到的问题是让序列化程序生成的AddFixedPriceItemRequest实际包含像BulkDataExchangeRequests元素那样的xmlns。这似乎是一个要求,以使其工作。我使用以下方法生成批量标记:
writer.WriteStartElement("BulkDataExchangeRequests", "urn:ebay:apis:eBLBaseComponents");
我创建了一个序列化程序。
serializer = new XmlSerializer(typeof(AddFixedPriceItemRequestType));//, "urn:ebay:apis:eBLBaseComponents");
并使用命名空间序列化
request = new AddFixedPriceItemRequestType()
{
//populate data.
};
XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
namespaces.Add("", "urn:ebay:apis:eBLBaseComponents");
serializer.Serialize(writer, request, namespaces);
这是具有xml属性的类型:
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.5420")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="urn:ebay:apis:eBLBaseComponents",TypeName="AddFixedPriceItemRequest")]
public partial class AddFixedPriceItemRequestType : AbstractRequestType {
//filled in class
}
我的输出结果如下:
<AddFixedPriceItemRequest xmlns="">
<ErrorLanguage xmlns="urn:ebay:apis:eBLBaseComponents">en_US</ErrorLanguage>
<Version xmlns="urn:ebay:apis:eBLBaseComponents">837</Version>
<Item p4:type="Item" xmlns:p4="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:ebay:apis:eBLBaseComponents">
有人可以帮忙解决如何设置addfixedpriceitemrequest的xmlns以通过序列化程序匹配批量xmlns。或者推荐另一种方法。我试图避免使用createelement / writeelement写出每个属性。

这对我有用
ItemType itemType = new ItemType()
{
//populate data.
};
ApiCall apiCall = new AddItemCall() { Item = itemType };
AddItemRequestType addFixedPriceItemRequestType = ((AddItemCall)apiCall).ApiRequest;
XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces(new XmlQualifiedName[] {
new XmlQualifiedName(string.Empty, "urn:ebay:apis:eBLBaseComponents")});
XmlSerializer xmlSerializer = new XmlSerializer(
addFixedPriceItemRequestType.GetType(), "urn:ebay:apis:eBLBaseComponents");
MemoryStream memoryStream = new MemoryStream();
xmlSerializer.Serialize(memoryStream, addFixedPriceItemRequestType , namespaces);
memoryStream.Seek((long)0, SeekOrigin.Begin);
XmlDocument xmlDocument = new XmlDocument();
xmlDocument.Load(memoryStream);
memoryStream.Close();
string addItemRequestTypeXML = xmlDocument.OuterXml;
输出将是:
<AddItemRequestType xmlns="urn:ebay:apis:eBLBaseComponents">
<Item>
<ApplicationData></ApplicationData>
<AutoPay>false</AutoPay>
<CategoryMappingAllowed>true</CategoryMappingAllowed>
<Country>US</Country>
<Currency>EUR</Currency>
<Description>
....
<AddItemRequestType>

问题最有可能在于XmlTypeAttribute
- 您似乎将自己的类用作顶级容器 - 您应该使用XmlRootAttribute
insted。这样,您就可以将urn:ebay:apis:eBLBaseComponents
放置在正确的位置。
样品:
void Main()
{
var t = new A {FieldOfB = new B {C = 5}};
var serializer = new XmlSerializer(typeof(A));
using (var writer = new StringWriter())
{
serializer.Serialize(writer, t);
writer.ToString().Dump();
}
}
与此类定义一起使用时:
[System.Xml.Serialization.XmlTypeAttribute(Namespace="urn:ebay:apis:eBLBaseComponents")]
public class A
{
public B FieldOfB {get;set;}
}
public class B
{
public int C {get;set;}
}
得出这个结果:
<?xml version="1.0" encoding="utf-16"?>
<A xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<FieldOfB xmlns="urn:ebay:apis:eBLBaseComponents">
<C>5</C>
</FieldOfB>
</A>
如果你修复了属性:
[System.Xml.Serialization.XmlRootAttribute(Namespace="urn:ebay:apis:eBLBaseComponents")]
public class A
{
public B FieldOfB {get;set;}
}
public class B
{
public int C {get;set;}
}
你明白了:
<?xml version="1.0" encoding="utf-16"?>
<A xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="urn:ebay:apis:eBLBaseComponents">
<FieldOfB>
<C>5</C>
</FieldOfB>
</A>

eBay仅需要在Trade API中设置名称空间。一种解决方案是删除BulkDataExchange对象中的命名空间设置,并仅在Trade API对象中添加命名空间设置。这不是标准的XML格式,但eBay只接受这一点。
在你的情况下,这可能会成为eBay的伎俩:
writer.WriteStartElement("BulkDataExchangeRequests", "");
