Question

I have a custom attribute that I want to apply to each methods in my WCF service.

I proceed like this:

[MyAttribute]
void MyMethod()
{

}

The problem is that my service contains hundreds of methods and I don’t want to write [Attribute] above all of them. Is there a way to apply the attribute to all my methods in my service?

Here’s my attribute’s signature:

//[AttributeUsage(AttributeTargets.Class)]
public class SendReceiveBehaviorAttribute : Attribute, /*IServiceBehavior,*/ IOperationBehavior

EDIT after Aliostad’s answer:

I tried this:

public void ApplyDispatchBehavior(ServiceDescription desc, ServiceHostBase host)
{
    foreach (ChannelDispatcher cDispatcher in host.ChannelDispatchers)
    {
        foreach (EndpointDispatcher eDispatcher in cDispatcher.Endpoints)
        {
            foreach (DispatchOperation op in eDispatcher.DispatchRuntime.Operations)
            {
                op.Invoker = new OperationInvoker(op.Invoker);
            }
        }
    }
}

And that:

public void AddBindingParameters(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase, Collection<ServiceEndpoint> endpoints, BindingParameterCollection bindingParameters)
{
    foreach (ChannelDispatcher cDispatcher in serviceHostBase.ChannelDispatchers)
    {
        foreach (EndpointDispatcher eDispatcher in cDispatcher.Endpoints)
        {
            foreach (DispatchOperation op in eDispatcher.DispatchRuntime.Operations)
            {
                op.Invoker = new OperationInvoker(op.Invoker);
            }
        }
    }
}

But it still don’t work.

Answer 1

According to IServiceBehaviour documentation, if you implement this interface and create an attribute and put it at the class level, it will be applied to all operations:

Create a custom attribute that
implements IServiceBehavior and use it
to mark service classes that are to be
modified. When a ServiceHost object is
constructed, uses reflection to
discover the attributes on the service
type. If any attributes implement
IServiceBehavior, they are added to
the behaviors collection on
ServiceDescription.

UPDATE

Instead of implementing IOperationBehaviour, add required behaviour in the IServiceBehaviour by looping through all operations:

foreach (EndpointDispatcher epDisp in chDisp.Endpoints)
{
    epDisp.DispatchRuntime.MessageInspectors.Add(this);
    foreach (DispatchOperation op in epDisp.DispatchRuntime.Operations)
    {
        op.ParameterInspectors.Add(this); // JUST AS AN EXAMPLE 
    }                        
}
