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
1、IEndpointBehavior
Endpoint.Behaviors.Add(IEndpointBehavior);
2、IContractBehavior
Endpoint.Contract.Behaviors.Add(IContractBehavior);
3、IOperationBehavior
foreach
(OperationDescription operationDescription
in
Endpoint.Contract.Operations)
{
operationDescription.Behaviors.Add(IOperationBehavior);
}
获取Client的Endpoint的方法：
1、ClientBase.Endpoint
2、ChannelFactory.Endpoint
