WCF服务中的奇怪序列化

Question

我在C＃上遇到了WCF服务的问题。

我尝试定义小服务：

using System.ServiceModel;

namespace TestApp
{
    [ServiceContractAttribute(Namespace = "http://testApp.ru/LittleService", Name = "ILittleService", ConfigurationName = "ILittleService")]
    public interface ILittleService
    {
        [OperationContract(Action = "urn:GetArrayOfCars")]
        [TransactionFlow(TransactionFlowOption.Allowed)]
        [XmlSerializerFormat]
        GetArrayOfCarsResponse GetArrayOfCars(GetArrayOfCarsRequest request);

        [OperationContract(Action = "urn:GetArrayOfTrains")]
        [TransactionFlow(TransactionFlowOption.Allowed)]
        [XmlSerializerFormat]
        GetArrayOfTrainsResponse GetArrayOfTrains(GetArrayOfTrainsRequest request);
    }
}

每个回复都会列出一系列汽车/火车：

namespace TestApp.ResponseWrappers
{
    [System.ServiceModel.MessageContractAttribute(WrapperName = "GetArrayOfCarsResponse", WrapperNamespace = "http://testApp.ru/LittleService", IsWrapped = true)]
    public class GetArrayOfCarsResponse
    {

        [System.ServiceModel.MessageBodyMemberAttribute(Namespace = "", Order = 0)]
        [System.Xml.Serialization.XmlArrayAttribute()]
        [System.Xml.Serialization.XmlArrayItemAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        public CarResult[] result { get; set; }

        public GetArrayOfCarsResponse()
        {
        }

        public GetArrayOfCarsResponse(CarResult[] result)
        {
            this.result = result;
        }
    }
}

和

namespace TestApp.ResponseWrappers
{
    [System.ServiceModel.MessageContractAttribute(WrapperName = "GetArrayOfTrainsResponse", WrapperNamespace = "http://testApp.ru/LittleService", IsWrapped = true)]
    public class GetArrayOfTrainsResponse
    {

        [System.ServiceModel.MessageBodyMemberAttribute(Namespace = "", Order = 0)]
        [System.Xml.Serialization.XmlArrayAttribute()]
        [System.Xml.Serialization.XmlArrayItemAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        public TrainResult[] result { get; set; }

        public GetArrayOfTrainsResponse()
        {
        }

        public GetArrayOfTrainsResponse(TrainResult[] result)
        {
            this.result = result;
        }
    }
}

当我尝试通过SoupUI使用此服务时：

GetArrayOfCars方法正常

对于GetArrayOfTrains方法，我遇到了一个奇怪的错误：

    ... 16 more

但服务方法运行正常（我调试它们）。在结果序列化阶段检测错误（通过SvcTraceViewer）：

Massage: Unable to cast object of type 'TestApp.Data.TrainResult[]' to type 'TestApp.Data.CarResult[]'.
StackTrace: Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationWriterIProductCatalogV2Part1.Write89_GetRegionalCatalogInfoResponse(Object[] p)
    System.Xml.Serialization.XmlSerializer.Serialize(XmlWriter xmlWriter, Object o, XmlSerializerNamespaces namespaces, String encodingStyle, String id)

在研究了这个问题后，我获得了服务的WSDL，并在其中找到了非常有趣的行：

<xs:complexType name="ArrayOfCarResult">
    <xs:sequence>
        <xs:element minOccurs="0" maxOccurs="unbounded" form="unqualified" name="CarResult" nillable="true" type="CarResult"/>
    </xs:sequence>
</xs:complexType>

<xs:element name="result" type="ArrayOfCarResult"/>

<xs:element name="GetArrayOfCarsResponse">
    <xs:complexType>
        <xs:sequence>
            <xs:element minOccurs="0" maxOccurs="1" ref="result"/>
        </xs:sequence>
    </xs:complexType>
</xs:element>

<xs:element name="GetArrayOfTrainsResponse">
    <xs:complexType>
        <xs:sequence>
            <xs:element minOccurs="0" maxOccurs="1" ref="result"/>
        </xs:sequence>
    </xs:complexType>
</xs:element>

如果我在响应中对数组使用不同的名称，则所有方法都可以正常工作。但我需要使用相似的名字。

对XmlArrayAttribute使用ElementName属性对我没有帮助（如果我使用＆＃34;结果＆＃34;字符串）。

有没有人遇到过这样的问题？
