EndpointDispatcher上带有Action ... ContractFilter不匹配的消息. [英] The message with Action ... ContractFilter mismatch at the EndpointDispatcher.

问题描述

当尝试在现有服务上执行所有其他方法正常运行的新方法时，出现以下错误.我没有接到我的服务的电话，因此不会产生任何内部错误，我可以捕捉到任何有关导致此错误的原因?:

I get the following error when attempting to execute a new method on an existing service where all other methods work without error.  I don't get a call to my service so no internal error is generated that I can catch, any ideas as to what is causing this?:

{System.ServiceModel.ActionNotSupportedException:由于EndpointDispatcher的ContractFilter不匹配，因此无法在接收方处理带有操作'DASvc/IScenarioDataService/ScenarioCloseService'的消息.这可能是由于合同不匹配(发送方和接收方之间的操作不匹配)或发送方和接收方之间的绑定/安全不匹配造成的.检查发送方和接收方是否具有相同的合同和相同的绑定(包括安全性要求，例如消息，传输，无).

{System.ServiceModel.ActionNotSupportedException: The message with Action 'DASvc/IScenarioDataService/ScenarioCloseService' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver.  Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).

新方法的代码:

[ ServiceContract (Namespace = " DASvc" )]

[ServiceContract(Namespace = "DASvc")]

公共 界面 IScenarioDataService

public interface IScenarioDataService

{

[ FaultContract ( typeof ( dasvcErrorFault ))]//新方法签名定义

[FaultContract(typeof(dasvcErrorFault))] // New Method signature definition

[ OperationContract ]

[OperationContract]

布尔型 ScenarioCloseService();

bool ScenarioCloseService();

...}

[ 操作行为 ]

[OperationBehavior]

公共 布尔型 ScenarioCloseService()

public bool ScenarioCloseService()

{

尝试

try

{

返回 true ;

return true;

}

捕获 ( 例外 ex)

catch (Exception ex)

{

字符串 userName = Thread .CurrentPrincipal.Identity.Name;

string userName = Thread.CurrentPrincipal.Identity.Name;

dasvcErrorFault fe = errHandlerObj.HandleError(例如， " CloseService用户:" + userName，loggerObj， LoggingUtility . callEventID .EconomicScenarioDataService);

dasvcErrorFault fe = errHandlerObj.HandleError(ex, "CloseService User: " + userName, loggerObj, LoggingUtility.callEventID.EconomicScenarioDataService);

投掷 新 FaultException < dasvcErrorFault >(fe);

throw new FaultException<dasvcErrorFault>(fe);

}

}

推荐答案

就像您尝试使用为新服务实例创建的代理来调用服务的旧实例一样.

如果您100％确定要调用的服务已安装并正在运行新方法，则应该可以通过打开服务的跟踪来进一步诊断此问题.

If you are 100% sure that the service you are calling has the new method installed and running, then you should be able to diagnose this further by turning on tracing on the service.
