Question

i have this code

public interface Interfcae1
    {
        void OP1();
    }

    public interface Interfcae2
    {
        void OP2();
    }

    public interface Interfcae3
    {
        void OP3();
    }

    public class Multi : Interfcae1, Interfcae2, Interfcae3
    {
        public void OP1()
        {
            System.Threading.Thread.Sleep(500);
        }

        public void OP2()
        {
            System.Threading.Thread.Sleep(1500);
        }

        public void OP3()
        {
            System.Threading.Thread.Sleep(2500);
        }
    }

i want to use unity to intercept all the function calls to test how much time it take for each call.

my main code is

IUnityContainer container = new UnityContainer();
container.AddNewExtension<Interception>();
container.RegisterType<Interfcae1, Multi>(
                        // new InjectionConstructor(typeof(string)),
                         new Interceptor<TransparentProxyInterceptor>(),
                         new InterceptionBehavior<InterceptBehavior>());
container.RegisterType<Interfcae2, Multi>(
                // new InjectionConstructor(typeof(string)),
                         new Interceptor<TransparentProxyInterceptor>(),
                         new InterceptionBehavior<InterceptBehavior>());
container.RegisterType<Interfcae2, Multi>(
                // new InjectionConstructor(typeof(string)),
                         new Interceptor<TransparentProxyInterceptor>(),
                         new InterceptionBehavior<InterceptBehavior>());

var proxy = container.Resolve<Multi>();

but at the resolve i am getting exception that the type is not interceptable

Did you remember to Configure?

var intp = container.Configure<Interception>()
    .SetInterceptorFor(qualifiedType, new TransparentProxyInterceptor());

After that, do an AddPolicy and you should be good to go… Remember to specify the type info for the interface to intercept, and the interception handler.

var policy = intp.AddPolicy("myFirstInterception");
policy.AddMatchingRule<TypeMatchingRule>(
    new InjectionConstructor(
        new InjectionParameter(typeof(Interface1))))
            .AddCallHandler(typeof(MyInterceptionHandler), 
                new ContainerControlledLifetimeManager());

Also try modifying the Multi class definition as:

public class Multi : MarshalByRefObject, Interfcae1, Interfcae2, Interfcae3
