我有XSD.exe工具生成的XSD。我要从Excel工作表加载数据并填充数据表，然后将其保存到XML文件中。如何序列化嵌套元素？
在我的模式中：（在提供者下可以有多个提供者，在ProviderSite下可以有多个ProviderSite）
<xs:element name="Providers">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" name="Provider">
<xs:complexType>
<xs:all>
<xs:element minOccurs="0" name="FederalTaxIdentifier" type="xs:string" />
<xs:element minOccurs="0" name="ProviderName" type="xs:string" />
<xs:element minOccurs="0" name="ContractualRelationshipCode" type="xs:string" />
<xs:element minOccurs="0" name="ProviderSites">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" name="ProviderSite">
<xs:complexType>
<xs:all>
<xs:element minOccurs="0" name="SiteIdentifier" type="xs:string" />
<xs:element minOccurs="0" name="SiteName" type="xs:string" />
<xs:element minOccurs="0" name="LicenseTypeCode" type="xs:string" />
<xs:element minOccurs="0" name="OpenDate" type="xs:string" />
<xs:element minOccurs="0" name="CloseDate" type="xs:string" />
<xs:element minOccurs="0" name="DirectorPrefixName" type="xs:string" />
<xs:element minOccurs="0" name="DirectorFirstName" type="xs:string" />
<xs:element minOccurs="0" name="DirectorMiddleInitial" type="xs:string" />
<xs:element minOccurs="0" name="DirectorLastName" type="xs:string" />
<xs:element minOccurs="0" name="DirectorPhoneNumber" type="xs:string" />
<xs:element minOccurs="0" name="NationalProviderIdentifier" type="xs:string" />
<xs:element minOccurs="0" name="WebAddress" type="xs:string" />
</xs:all>
</xs:complexType>
</xs: element>
</xs:complexType>
</xs:all>
</xs:element>
</xs:sequence>
在我的C＃中，我创建了Providers-> Provider
元素的新实例。ProvidersProvider prov = new ProvidersProvider();
然后我访问一个对象并将其设置为数据表中的单元格
prov.FederalTaxIdentifier = DtRow.ItemArray[0].ToString();
然后将其序列化为xml
serializer.Serialize(writer, prov);
试图弄清楚如何访问和添加其他元素，例如Providers-> Provider-> ProviderSites-> ProviderSite-> SiteIdentifier
更新 我在xsd中添加了xs：choice元素，并重新生成了该类。 我该如何设置这些元素？
<xs:element minOccurs="0" name="ProviderSitePhones">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" name="ProviderSitePhone">
<xs:complexType>
<xs:sequence>
<xs:choice maxOccurs="unbounded">
<xs:element minOccurs="0" name="TypeCode" type="xs:string" />
<xs:element minOccurs="0" name="PhoneNumber" type="xs:string" />
</xs:choice>
</xs:sequence>
<xs:attribute name="action" type="xs:string" use="optional" />
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>

在我的Program.cs中，我有：
ProviderSitePhones = provider.Value.Select(ProviderSitePhone => new ProvidersProviderProviderSiteProviderSitePhone()
{
