使用温莎城堡时如何注入属性

Question

I am new to IOC.

I've MethodProfilerAspectAttribute attribute which has to be applied on any method like this

[MethodProfilerAspectAttribute(5)]
public void MethodName(){}

Here is the implementation of MethodProfilerAspectAttribute

[Serializable]
[AttributeUsage(AttributeTargets.Method, AllowMultiple = false)]
public sealed class MethodProfilerAspectAttribute : OnMethodBoundaryAspect
{
        public ILogger logger { get; set; }
        public int x{get;set;}
        public MethodProfilerAspectAttribute(int x)
        {
            this.x=x;
        }
    public override void OnSuccess(MethodExecutionArgs args)
        {
            logger.CustomLogging("logMe");
            base.OnSuccess(args);
        }
}

I want to resolve my ILogger dependency using Log4NetLogger which is registered and resolving constructor dependencies properly by using following :

container.Register(Component.For<ILogger>().ImplementedBy(typeof(Log4NetLogger)));

but unfortunately whatever I've tried for resolving property dependency, is not working.

Any help would be greatly appreciated.

The link you provided just describes property injection for components resolved from the container. Attributes are not resolved from the container, but instead are created by the CLR. You might be able to jigger a way to set attribute properties by providing a custom IContributeComponentModelConstruction implementation, but I'm not so sure. See answers for similar questions here , here , and here (from the creator of Windsor).

In any case, attributes is not where you want to put functionality. They should be minimal, just providing metadata. I see here you're trying to provide some sort of functionality across all method invocations. You may want to consider Windsor's interceptors to provide similar behavior.
