C#使用基类作为WCF服务的参数我有一个多项目的解决方案。一个项目提供了一个包含多个类的DLL。其中一个类是WorkerTemplate。另外两个类继承自它，即ExecSQLWorker和CopyWorkerclassExecSQLWorker:WorkerTemplate{};类CopyWorker：WorkerTemplate{};在我的WCF服务中，我有我的接口：publicinterfaceIPQWService{[OperationContract]voidEnqueueWorker(WorkerTemplate[]worker);现在，在我的客户端应用程序中，WorkerTemplate[]由ExecSQLWorker和CopyWorker对象组成。当我现在尝试调用EnqueueWorker(worker)方法时，我收到一条错误消息，告诉我序列化工作类时出现问题。所以我猜是因为服务确实序列化基类有问题，而不是获取继承类。但如何轻松解决这个问题？InnerException消息是“类型‘DV_BII30.ExecSQLWorker’，数据协定名称‘ExecSQLWorker：http://schemas.datacontract.org/2004/07/DV_BII30’不是预期的。如果您正在使用DataContractSerializer或将任何静态未知类型添加到已知类型列表中，请考虑使用DataContractResolver-例如，通过使用KnownTypeAttribute属性或将它们添加到传递给序列化程序的已知类型列表中。有关详细信息，请参阅InnerException。--->System.Runtime.Serialization.SerializationException:类型'DV_BII30.ExecSQLWorker'数据协定名称为'ExecSQLWorker:http://schemas.datacontract.org/2004/07/DV_BII30'不是预期的。如果您正在使用DataContractSerializer或添加任何未知类型，请考虑使用DataContractResolver策略地添加到已知类型列表-例如，通过使用KnownTypeAttribute属性或将它们添加到传递给序列化程序的已知类型列表中。在System.Runtime.Serialization.XmlObjectSerializerWriteContext.SerializeAndVerifyType(DataContractdataContract,XmlWriterDelegatorxmlWriter,Objectobj,BooleanverifyKnownType,RuntimeTypeHandledeclaredTypeHandle,TypedeclaredType)在System.Runtime.Serialization.XmlObjectSerializerWriteContext.SerializeWithXsijandleobjectHriterType,ObjectHriterWriterDelegator对象,XMLobjectType,Int32declaredTypeID,RuntimeTypeHandledeclaredTypeHandle,TypedeclaredType)在System.Runtime.Serialization.XmlObjectSerializerWriteContext.InternalSerialize(XmlWriterDelegatorxmlWriter,Objectobj,BooleanisDeclaredType,BooleanwriteXsiType,Int32declaredTypeID,RuntimeTypeHandledeclaredTypeHandle)在WriteArrayOfWorkerTemplateToXml(ObjectDelegatorXml,ObjectDelegatorXmlObjectSerializerWriteContext,CollectionDataContract)在System.Runtime.Serialization.CollectionDataContract.WriteXmlValue(XmlWriterDelegatorxmlWriter,Objectobj,XmlObjectSerializerWriteContextcontext)在System.Runtime.Serialization.XmlObjectSerializerWriteContext.WriteDataContractValue(DataContractdataContractType,XmlWriterDelegatorobjectxmlWriter)声明于System.Runtime.Serialization.XmlObjectSerializerWriteContext.WriteDataContractValueRuntime.Serialization.XmlObjectSerializerWriteContext.SerializeWithoutXsiType（DataContractdataContract，XmlWriterDelegatorxmlWriter，Objectobj，RuntimeTypeHandledeclaredTypeHandle）在System.Runtime.Serialization.DataContractSerializer.InternalWriteObjectContent（XmlWriterDelegator编写器，对象图，DataContractResolverdataContractInterriteResolverData）在System.Runtime。（XmlWriterDelegator编写器、对象图、DataContractResolverdataContractResolver）在System.Runtime.Serialization.XmlObjectSerializer.WriteObjectHandleExceptions（XmlWriterDelegator编写器，对象图，DataContractResolverdataContractResolver）在System.Runtime.Serialization.XmlObjectSerializer.WriteObject（XmlDictionaryWriter编写器，对象图）在System.ServiceModel.Dispatcher.DataContractSerializerOperationFormatter.SerializeParameterPart（XmlDictionaryWriter对象编写器，PartInfo部分）---内部异常堆栈跟踪结束---服务器堆栈跟踪：在System.ServiceModel.Dispatcher.DataContractSerializerOperationFormatter.SerializeParameterPart（XmlDictionaryWriter编写器，PartInfo部分，对象图）在System.ServiceModel.Dispatcher.DataContractSerializerOperationFormatter.SerializeParameter（XmlDictionaryWriter编写器，PartInfo部分，对象图）在System.ServiceModel.Dispatcher.DataContractSerializerOperationFormatter.SerializeParameters（XmlDictionaryWriter编写器，PartInfo[]部分，Object[]参数）在System.ServiceModel.Dispatcher.DataContractSerializerOperationFormatter.SerializeBody（XmlDictionaryWriter编写器，MessageVersion版本，字符串操作，MessageDescriptionmessageDescription，对象returnValue，Object[]参数，BooleanisRequest）在System.ServiceModel.Dispatcher.OperationFormatter.SerializeBodyContents（XmlDictionaryWriter编写器，MessageVersion版本，Object[]参数，ObjectreturnValue，布尔值isRequest）在System.ServiceModel.Dispatcher.OperationFormatter.OperationFormatterMessage.OperationFormatterBodyWriter.OnWriteBodyContents（XmlDictionaryWriter作者）在System.ServiceModel.Channels.BodyWriterMessage.OnWriteBodyContents（XmlDictionaryWriter作者）)在System.ServiceModel.Channels.BufferedMessageWriter.WriteMessage(Messagemessage,BufferManagerbufferManager,Int32initialOffset,Int32maxSizeQuota)在System.ServiceModel.Channels.TextMessageEncoderFactory.TextMessageSystem.ServiceModel.Channels.HttpOutput.SerializeBufferedMessage（消息消息，布尔值shouldRecycleBuffer）在System.ServiceModel.Channels.HttpOutput.Send（TimeSpan超时）处的Encoder.WriteMessage（消息消息，Int32maxMessageSize，BufferManagerbufferManager，Int32messageOffset）。ServiceModel.Channels.HttpChannelFactory`1.HttpRequestChannel.HttpChannelRequest.SendRequest（消息消息，TimeSpan超时）在System.ServiceModel.Channels.RequestChannel.Request（消息消息，TimeSpan超时）在System.ServiceModel.Dispatcher.RequestChannelBinder.Request（消息消息，TimeSpan超时）在System.ServiceModel.Channels.ServiceChannel.Call（字符串操作，布尔单向，ProxyOperationRuntime操作，Object[]ins，Object[]outs，TimeSpan超时）在System.ServiceModel.Channels.ServiceChannelProxy.InvokeService（IMethodCallMessagemethodCall,ProxyOperationRuntime运行）在System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessagemessage)Excep
