Paul,

If you implement a custom dynamic object you can do that (I think). I think even then you have to do a bit of work to make sure you publish the appropriate metadata when Reflection requests it. If you use ExpandoObject then no - there's no type information at all and no Reflection. So this:

            dynamic expando = new ExpandoObject();
            expando.Name = "Rick Strahl";
            expando.Company = "West Wind Technologies";

            // fails
            string name = ReflectionUtils.GetProperty(expando, "Name") as string;

fails because the property definition doesn't exist on dynamic. This makes binding a bit difficult (for example with my custom Web data binder)

Underneath the covers the properties are stored in a dictionary and I don't think Reflection actually works against Expando objects so I kind of doubt it works but I'm not sure... interesting to try out (don't have time this second tho :-))
