WCF同一IParameterInspector用于服务上的所有操作

多亏了 this 随后 this ,我找到了我要找的东西。

IParameterInspector IOperationBehavior 水平。他们可以在 IServiceBehavior 水平。在服务级别 ApplyDispatchBehavior

全班同学。。。

[AttributeUsage(AttributeTargets.Class)]
public class ServiceLevelParameterInspectorAttribute : Attribute, IParameterInspector, IServiceBehavior
{
    public object BeforeCall(string operationName, object[] inputs)
    {
       // Inspect the parameters.
        return null;
    }

    public void AfterCall(string operationName, object[] outputs, object returnValue, object correlationState)
    {
    }

    public void Validate(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
    {
    }

    public void AddBindingParameters(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase, Collection<ServiceEndpoint> endpoints, BindingParameterCollection bindingParameters)
    {
    }

    public void ApplyDispatchBehavior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
    {
        foreach (ChannelDispatcher channelDispatcher in serviceHostBase.ChannelDispatchers)
        {
            if (channelDispatcher == null)
            {
                continue;
            }

            foreach(var endPoint in channelDispatcher.Endpoints)
            {
                if (endPoint == null)
                {
                    continue;
                }

                foreach(var opertaion in endPoint.DispatchRuntime.Operations)
                {
                    opertaion.ParameterInspectors.Add(this);
                }
            }
        }
    }
}
