在C#WCF数据成员集合上构建SOAP消息时出现问题

我正在创建一个简单的WCF服务来接受下面的SOAP消息

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:jvm="http://siph.com/JVM">
   <soapenv:Header/>
   <soapenv:Body>
      <jvm:MT_MedicationOrder>
         <Patientid>?</Patientid>
         <Case_number>?</Case_number>
         <DateTime>?</DateTime>
         <Order>
            <MedicationOrder_id>?</MedicationOrder_id>
            <Descr_of_order>?</Descr_of_order>
            <!--Optional:-->
            <Medication_req_type>?</Medication_req_type>
            <!--Zero or more repetitions:-->
            <Infusion_ingredient>
               <Order_Id>?</Order_Id>
               <DrugID>?</DrugID>
               <DrugType>?</DrugType>
            </Infusion_ingredient>
         </Order>
      </jvm:MT_MedicationOrder>
   </soapenv:Body>
</soapenv:Envelope>

药品订单交易服务合同

[ServiceContract(Namespace = "http://siph.com/JVM")]
    public interface IMedicationOrder
    {
        [OperationContract]
        MedicationOrderResponse ProcessOrder(MedicationOrderRequest req);
    }

    [MessageContract(WrapperName = "MT_MedicationOrder")]
    public class MedicationOrderRequest
    {
        //[MessageHeader]
        //public string Dummy;

        #region Message Body
        [MessageBodyMember(Namespace = "", Name = "Patientid", Order = 1)]
        public string PatientId;

        [MessageBodyMember(Namespace = "", Name = "Case_number", Order = 2)]
        public string CaseNumber;

        [MessageBodyMember(Namespace = "", Name = "DateTime", Order = 3)]
        public string RequestDateTime;

        [MessageBodyMember(Namespace = "", Name = "Order", Order = 4)]
        public MedicationOrderTransaction OrderTransaction;
        #endregion
    }

[DataContract(Namespace = "")]
    public class MedicationOrderTransaction
    {
        [DataMember(Name = "MedicationOrder_id", Order = 1, IsRequired = true)]
        public string MedicationOrderID;
        [DataMember(Name = "Descr_of_order", Order = 2)]
        public string DescriptionOfOrder;
        
        [DataMember(Name = "Medication_req_type", Order = 55)]
        public string MedicationReqType;
        [DataMember(Name = "Infusion_ingredient", Order = 56)]
        public List<InfusionIngredientTransactionList> infusionIngredient;
    }

[DataContract]
    public class InfusionIngredientTransactionList
    {
        [DataMember(Name = "Order_Id", Order = 1)]
        public string OrderID;
        [DataMember(Name = "Drug_Id", Order = 2)]
        public string DrugID;
        [DataMember(Name = "DrugType", Order = 3)]
        public string DrugType;
    }

结果：请注意，siph:InfusionCreditionTransactionList的集合是在Infusion\u配料节点内创建的，而不是应该作为集合的Infusion\u配料本身。

   <soapenv:Header/>
   <soapenv:Body>
      <jvm:MT_MedicationOrder>
         <Patientid>?</Patientid>
         <Case_number>?</Case_number>
         <DateTime>?</DateTime>
         <Order>
            <MedicationOrder_id>?</MedicationOrder_id>
            <Descr_of_order>?</Descr_of_order>
            <Medication_req_type>?</Medication_req_type>
            <!--Optional:-->
            <Infusion_ingredient>
             <!--Zero or more repetitions:-->
             <siph:InfusionIngredientTransactionList>
              <!--Optional:-->
              <siph:Order_Id>?</siph:Order_Id>
              <!--Optional:-->
              <siph:Drug_Id>?</siph:Drug_Id>

              <siph:DrugType>?</siph:DrugType>
             </siph:InfusionIngredientTransactionList>
           </Infusion_ingredient>
         </Order>
      </jvm:MT_MedicationOrder>
   </soapenv:Body>
</soapenv:Envelope>

请告诉我我做错了什么。谢谢。

我还不能“评论”，所以请尝试回答。因此，这个建议可能有点离题，但这是否有助于：

    [DataMember(Name = "Infusion_ingredient", Order = 56)]
    public List<InfusionIngredientTransactionList> infusionIngredient { get; set; } = new List<InfusionIngredientTransactionList>();

[DataMember（Name=“Infusion\u component”，Order=56）]
公共列表输入元素{get；set；}=new List（）；

我还同意C#类应该位于List属性之上，因为类的对象被添加到List集合中。如果不是关于主题或没有帮助，我深表歉意。

列表的Xml序列化会自动创建两个Xml元素。两个防止两个xml元素需要放入list属性上方的c#类：[XmlElement（）]声明一个元素只会创建一个标记。我认为您可以使用消息约定，它允许您指定所需SOAP消息的精确结构。有关message contract的更多信息，请参阅以下链接：
