WCF学习笔记三：使用自定义行为扩展WCF总结

服务站: 使用自定义行为扩展 WCF文中详细的描述了自定义行为扩展点，下面对这些扩展点的扩展方法进行总结

调度程序扩展点
1、消息检查：EndpointDispatcher.DispatchRuntime.MessageInspectors.Add(IDispatchMessageInspector);
2、操作选择器：EndpointDispatcher.DispatchRuntime.OperationSelector = IDispatchOperationSelector;
3、消息格式化（反序列化）：DispatchOperation.Formatter = IDispatchMessageFormatter;
4、参数检查：DispatchOperation.ParameterInspectors.Add(IparameterInspector);
5、操作调用程序：DispatchOperation.Invoker = IOperationInvoker;

获取DispatchRuntime实例的几种方式【DispatchRuntime 类】

a、在ServiceHost中

            foreach (ChannelDispatcher cDispatcher in host.ChannelDispatchers)
                foreach (EndpointDispatcher endpointDispatcher in cDispatcher.Endpoints)
                    endpointDispatcher.DispatchRuntime...

b、在IServiceBehavior接口的ApplyDispatchBehavior中

        public void ApplyDispatchBehavior(ServiceDescription serviceDescription, 

System.ServiceModel.ServiceHostBase serviceHostBase)
        {
            foreach (ChannelDispatcher cDispatcher in serviceHostBase.ChannelDispatchers)
                foreach (EndpointDispatcher endpointDispatcher in cDispatcher.Endpoints)
                    endpointDispatcher.DispatchRuntime...
        }

c、在IEndpointBehavior接口的ApplyDispatchBehavior中

        public void ApplyDispatchBehavior(ServiceEndpoint endpoint, 

System.ServiceModel.Dispatcher.EndpointDispatcher endpointDispatcher)
        {
            endpointDispatcher.DispatchRuntime...
        }

 
d、在IContractBehavior接口的ApplyDispatchBehavior中

        public void ApplyDispatchBehavior(ContractDescription contractDescription, 

ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.DispatchRuntime dispatchRuntime)
        {
            dispatchRuntime...
        }

 获取DispatchOperation实例的几种方式【DispatchOperation类】
a、在IOperationBehavior接口的ApplyDispatchBehavior中

        public void ApplyDispatchBehavior(OperationDescription operationDescription, 

System.ServiceModel.Dispatcher.DispatchOperation dispatchOperation)
        {
            dispatchOperation...
        }

 
b、在DispatchRuntime实例中

            foreach (DispatchOperation dispatchOperation in DispatchRuntime.Operations)
                dispatchOperation...

代理（客户端）扩展点
1、参数检查：ClientOperation.ParameterInspectors.Add(IparameterInspector);
2、消息格式化（序列化）：ClientOperation.Formatter = IClientMessageFormatter;
?、操作选择器：ClientRuntime.OperationSelector = IClientOperationSelector;
3、消息检查：ClientRuntime.MessageInspectors.Add(IClientMessageInspector);

获取ClientRuntime实例的几种方式【ClientRuntime类】
a、在IEndpointBehavior接口的ApplyClientBehavior中

        public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
        {
            clientRuntime...
        }

 
b、在IContractBehavior接口的ApplyClientBehavior中

        public void ApplyClientBehavior(ContractDescription contractDescription, ServiceEndpoint 

endpoint, System.ServiceModel.Dispatcher.ClientRuntime clientRuntime)
        {
            clientRuntime...
        }

获取ClientOperation实例的几种方式【ClientOperation类】
a、在IOperationBehavior接口的ApplyClientBehavior中

        public void ApplyClientBehavior(OperationDescription operationDescription, 

System.ServiceModel.Dispatcher.ClientOperation clientOperation)
        {
            clientOperation...  
        }

b、在ClientRuntime实例中

            foreach(ClientOperation clientOperation in ClientRuntime.Operations)
                clientOperation...

将I...Behavior添加到ServiceHost中的方法
1、IServiceBehavior

            ServiceHost.Description.Behaviors.Add(IServiceBehavior);

2、IEndpointBehavior

            foreach (ServiceEndpoint endpoint in ServiceHost.Description.Endpoints)
            {
                endpoint.Behaviors.Add(IEndpointBehavior);
            }

3、IContractBehavior

            foreach (ServiceEndpoint endpoint in ServiceHost.Description.Endpoints)
            {
                endpoint.Contract.Behaviors.Add(IContractBehavior);
            }

4、IOperationBehavior

            foreach (ServiceEndpoint endpoint in ServiceHost.Description.Endpoints)
            {
                foreach (OperationDescription operationDescription in endpoint.Contract.Operations)
                {
                    operationDescription.Behaviors.Add(IOperationBehavior);
                }
            }

将I...Behavior添加到Client的Endpoint中的方法

            Endpoint.Behaviors.Add(IEndpointBehavior);

2、IContractBehavior

            Endpoint.Contract.Behaviors.Add(IContractBehavior);
