我目前正在开发一种生成 XML 文件的服务，该服务遵循发票的 UBL 标准，因此我需要使用一些提供的 XSD 模式。
我正在使用 .NET C# 进行开发，并找到了一种可以将 XSD 映射到 C# 类的方法——通过使用 XSD.exe——这看起来可以吗？
我面临的问题是，xsd 文件中还有其他命名空间，这似乎给我生成的类（xsd：imports）带来了一些问题：
<!-- ===== xsd:schema Element With Namespaces Declarations ===== -->
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
targetNamespace="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2"
xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2"
xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"
xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2"
xmlns:udt="urn:un:unece:uncefact:data:specification:UnqualifiedDataTypesSchemaModule:2"
xmlns:ccts="urn:un:unece:uncefact:documentation:2"
xmlns:ext="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2"
xmlns:qdt="urn:oasis:names:specification:ubl:schema:xsd:QualifiedDatatypes-2"
elementFormDefault="qualified"
attributeFormDefault="unqualified"
version="2.0">
<!-- ===== Imports ===== -->
<xsd:import namespace="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" schemaLocation="../common/UBL-CommonAggregateComponents-2.0.xsd"/>
<xsd:import namespace="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2" schemaLocation="../common/UBL-CommonBasicComponents-2.0.xsd"/>

<xsd:import namespace="urn:oasis:names:specification:ubl:schema:xsd:QualifiedDatatypes-2" schemaLocation="../common/UBL-QualifiedDatatypes-2.0.xsd"/>
<!-- ===== Root Element ===== -->
<xsd:element name="Invoice" type="InvoiceType">

我使用以下命令运行 xsd.exe：
xsd.exe /c C:\Users\tn\Downloads\os-UBL-2.0\os-UBL-2.0\xsd\maindoc\UBL-Invoice-2.0.xsd C:\Users\tn\Downloads\os-UBL-2.0\os-UBL-2.0\xsd\common\UBL-CommonAggregateComponents-2.0.xsd C:\Users\tn\Downloads\os-UBL-2.0\os-UBL-2.0\xsd\common\UBL-CommonBasicComponents-2.0.xsd C:\Users\tn\Downloads\os-UBL-2.0\os-UBL-2.0\xsd\common\UnqualifiedDataTypeSchemaModule-2.0.xsd C:\Users\tn\Downloads\os-UBL-2.0\os-UBL-2.0\xsd\common\UBL-CommonExtensionComponents-2.0.xsd C:\Users\tn\Downloads\os-UBL-2.0\os-UBL-2.0\xsd\common\UBL-QualifiedDatatypes-2.0.xsd C:\Users\tn\Downloads\os-UBL-2.0\os-UBL-2.0\xsd\common\CodeList_UnitCode_UNECE_7_04.xsd C:\Users\tn\Downloads\os-UBL-2.0\os-UBL-2.0\xsd\common\CodeList_MIMEMediaTypeCode_IANA_7_04.xsd C:\Users\tn\Downloads\os-UBL-2.0\os-UBL-2.0\xsd\common\CodeList_LanguageCode_ISO_7_04.xsd C:\Users\tn\Downloads\os-UBL-2.0\os-UBL-2.0\xsd\common\CodeList_CurrencyCode_ISO_7_04.xsd
当我尝试使用生成的代码来制作 XML 文件时，输出看起来像这样，其中缺少导入和命名空间前缀，并且最终导致验证失败。
<?xml version="1.0" encoding="utf-8"?>
<Invoice xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2">
<UBLVersionID xmlns="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">2.0</UBLVersionID>
<LegalMonetaryTotal xmlns="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2">
<LineExtensionAmount currencyID="DKK" xmlns="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">200</LineExtensionAmount>
<PayableAmount currencyID="DKK" xmlns="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">300</PayableAmount>
</LegalMonetaryTotal>
</Invoice>
这里是 som 示例代码，我通过 xmlserializer 从生成的类生成 XML
XmlSerializer mySerializer = new XmlSerializer(typeof(InvoiceType));
InvoiceType invoice = new InvoiceType();
UBLVersionIDType UVer = new UBLVersionIDType();
UVer.Value = "2.0";
invoice.UBLVersionID = UVer;
MonetaryTotalType mtt = new MonetaryTotalType();
LineExtensionAmountType lep = new LineExtensionAmountType();
lep.currencyID = CurrencyCodeContentType.DKK;
lep.Value = 200;
PayableAmountType pat = new PayableAmountType();
pat.currencyID = CurrencyCodeContentType.DKK;
pat.Value = 300;
mtt.LineExtensionAmount = lep;
mtt.PayableAmount = pat;
invoice.LegalMonetaryTotal = mtt;
StreamWriter sw = new StreamWriter(@"C:\New folder\test2.xml");
mySerializer.Serialize(sw, invoice);
sw.Close();
我该如何解决这个问题，这是在 .NET 中制作遵循 xsd 模式的 XML 的正确（最佳/最简单）方法吗？
