我有这样的父母xsd

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           targetNamespace="http://tempuri.org/"
           xmlns:ns2="http://schemas.datacontract.org/2004/07/Lia.Core.Models.Masterdata"
           elementFormDefault="qualified" attributeFormDefault="qualified">
    <xs:import namespace="http://schemas.datacontract.org/2004/07/Lia.Core.Models.Masterdata" schemaLocation="masterdataelements.xsd" />
    <xs:element name="UploadCostCentres">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="costcentres" minOccurs="0">
                    <xs:complexType>
                        <xs:sequence>
                            <xs:element name="CostCentre" type="ns2:CostCentre" minOccurs="0" maxOccurs="unbounded"/>
                        </xs:sequence>
                    </xs:complexType>
                </xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
    <xs:element name="UploadCostCentresResponse">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="status" type="xs:string" minOccurs="0"></xs:element>
                <xs:element name="message" type="xs:string" minOccurs="0"></xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>

并且还有如下类型的导入xsd

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           targetNamespace="http://schemas.datacontract.org/2004/07/Lia.Core.Models.Masterdata"
           xmlns:tns="http://schemas.datacontract.org/2004/07/Lia.Core.Models.Masterdata"
           elementFormDefault="qualified">
    <xs:complexType name="CostCentre">
        <xs:sequence>
            <xs:element name="CompanyCode" type="xs:string" minOccurs="0"></xs:element>
            <xs:element name="CostCentreName" type="xs:string" minOccurs="0"></xs:element>
            <xs:element name="CostCentreNo" type="xs:string" minOccurs="0"></xs:element>
            <xs:element name="Division" type="xs:string" minOccurs="0"></xs:element>
        </xs:sequence>
    </xs:complexType>
    <xs:element name="CostCentre" nillable="true" type="tns:CostCentre"/>
</xs:schema>

当我发送这样的soap请求时

<SOAP-ENV:Body>
      <ns1:UploadCostCentres xmlns:ns1="http://tempuri.org/">
        <ns1:costcentres>
            <ns2:CostCentre xmlns:ns2="http://schemas.datacontract.org/2004/07/Lia.Core.Models.Masterdata">
                <ns2:CompanyCode>6200</ns2:CompanyCode>
                <ns2:CostCentreName>Med Trsf Ingst VD(SS</ns2:CostCentreName>
                <ns2:CostCentreNo>0000063190</ns2:CostCentreNo>
                <ns2:Division>SuperSport International</ns2:Division>
            </ns2:CostCentre>
        </ns1:costcentres>
      </ns1:UploadCostCentres>
   </SOAP-ENV:Body>

已解析上面的soap主体，但ns1:此列表元素具有空值
但如果我通过这样的请求

<SOAP-ENV:Body>
      <ns1:UploadCostCentres xmlns:ns1="http://tempuri.org/">
        <ns1:costcentres>
            <ns1:CostCentre xmlns="http://schemas.datacontract.org/2004/07/Lia.Core.Models.Masterdata">
                <CompanyCode>6200</CompanyCode>
                <CostCentreName>Med Trsf Ingst VD(SS</CostCentreName>
                <CostCentreNo>0000063190</CostCentreNo>
                <Division>SuperSport International</Division>
            </ns1:CostCentre>
        </ns1:costcentres>
      </ns1:UploadCostCentres>
   </SOAP-ENV:Body>

然后它工作并传递正确的值。有人能告诉我如何使用嵌套的名称空间前缀。
