Interception Attributes are not supported on interfaces about ninject.extensions.interception

[remogloor]

Implemented in 6182460

Interface procies allow now interception attributes. They must be declared on the implementation type not on the interface due to a limitation of .NET.

Remo, can you please explain what you mean by, 'They must be declared on the implementation type not on the interface due to a limitation of .NET'? I am currently struggling with the issue of how to get the parameters from attributes applied to methods, from inside the interceptor. I gather fromt he context of this bug when it was logged that this might be the answer but when I do:

var attrs = invocation.Request.Method.GetCustomAttributes(typeof(AuthorizeAttribute), true);

..attrs is empty.

My Attribute is simple:

public class AuthorizeAttribute : InterceptAttribute
{
    public string[] AttributeParameters { get; private set; }

    public AuthorizeAttribute(params string[] parameters) {
        AttributeParameters = parameters;
    }

    public override IInterceptor CreateInterceptor(IProxyRequest request) {
        return request.Context.Kernel.Get<AuthorizationInterceptor>();
    }
}

Being applied in its most simplistic form possible at the moment:

    [Authorize("Test")]
    public virtual Result<Vault> Vault(DateTime date, bool LiveMode = true, int? SnapshotId = null)
    {
         ...
    }

I had tried doing the following at first. and adding a constructor in my IInterceptor implementation but it doesnt work:

    public override IInterceptor CreateInterceptor(IProxyRequest request) {
        var param = new List<Parameter>();
        int index = 0;
        foreach(string p in AttributeParameters) {
            param.Add(new ConstructorArgument(index++.ToString(), p));
        }
        return request.Context.Kernel.Get<AuthorizationInterceptor>(param.ToArray());
    }

when on my interceptor I had this:

    public AuthorizationInterceptor(IParameter[] parameters) {
        AttributeParameters = parameters;
    }

It actually calls into the constructor, but parameters has no values.
