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
