Возможно, вы искали IOperationInvoker
:
public class MyOperationInvoker : IOperationInvoker
{
IOperationInvoker originalInvoker;
public MyOperationInvoker(IOperationInvoker originalInvoker)
{
this.originalInvoker = originalInvoker;
}
public bool IsSynchronous { get { return originalInvoker.IsSynchronous; } }
public object[] AllocateInputs() { return originalInvoker.AllocateInputs(); }
public object Invoke(object instance, object[] inputs, out object[] outputs)
{
//Do stuff before call
var res = this.originalInvoker.Invoke(instance, inputs, out outputs);
//stuff after call
return res;
}
public IAsyncResult InvokeBegin(object instance, object[] inputs,
AsyncCallback callback, object state)
{
//Do stuff before async call
var res = this.originalInvoker.InvokeBegin(instance, inputs, callback, state);
return res;
}
public object InvokeEnd(object instance, out object[] outputs, IAsyncResult result)
{
var res = this.InvokeEnd(instance, out outputs, result);
//Do stuff after async call
return res;
}
}
Реализовано как атрибут для всех операций в службе:
public class MyBehaviorAttribute : Attribute, IServiceBehavior, IOperationBehavior
{
//IOperationBehavior
public void ApplyDispatchBehavior(OperationDescription operationDescription,
DispatchOperation dispatchOperation)
{
dispatchOperation.Invoker = new MyOperationInvoker(dispatchOperation.Invoker);
}
public void AddBindingParameters(OperationDescription operationDescription,
BindingParameterCollection bindingParameters) { /*Do nothing*/ }
public void ApplyClientBehavior(OperationDescription operationDescription,
ClientOperation clientOperation) { /*Do nothing*/ }
public void Validate(OperationDescription operationDescription) { /*Do nothing*/ }
//IServiceBehavior
public void Validate(ServiceDescription serviceDescription,
ServiceHostBase serviceHostBase) { /*Do nothing*/ }
public void AddBindingParameters(ServiceDescription serviceDescription,
ServiceHostBase serviceHostBase,
Collection<ServiceEndpoint> endpoints,
BindingParameterCollection bindingParameters) { /*Do nothing*/ }
public void ApplyDispatchBehavior(ServiceDescription serviceDescription,
ServiceHostBase serviceHostBase)
{
foreach (ServiceEndpoint endpoint in serviceHostBase.Description.Endpoints)
{
foreach (var operation in endpoint.Contract.Operations)
{
operation.Behaviors.Add(this);
}
}
}
А сервис:
[MyBehavior]
public class HelloService : IHelloService
{
...
}
