RE: [Rubydotnet-developer] System.Reflection.Binder

[Ben S. <bsc...@pr...>]

Hi Thomas,

We had similar feelings about the default binder, its functionality, and =
its private-ness.

What we've done is to delegate to the default binder instead of inherit =
from its class.  We do parameter conversions when necessary - almost =
exactly like your pseudocode! - and then ask the default binder if it =
can find a match.  The binder interface provides us with a list of =
possible matches, so we do loop over all of them looking for a =
conversion set that allows the default binder to bind something (if that =
makes sense).

If you have any questions about the above or other aspects of the =
binding - please ask!

Regards,
Ben

Hi guys,

I've been doing things a little backwards and I've now got interface
implementation from ruby running. I've also got the code ready for =
creating
a delegate from a proc, but I'm still missing the plumming to use it. =
I'm
wondering how to automatically convert proc objects into the appropriate
Delegate type. Type.InvokeMember uses a System.Reflection.Binder object =
to
do the actual binding, so I could subclass Binder and have it do it.
Unfortunately you cannot subclass the default binder and I'm not keen on
having to replicate whatever functionality is in it, especially as I =
don't
really know all of what it does.

How have you gone about this problem?

I wish there was a way to add specific parameter conversions that would =
be
allowed during member resolution and binding, without having to =
sacrifice
the properties of the default binder. All I really want is that during
parameter matching, the following would be considered (pseudo code)

if (requiredParameterType is a delegateType && actualParameter is IProc)
    convertedParameter =3D =
TypedDelegateFactory.create(requiredParameterType,
actualParameter, "call')

(Type TypedDelegateFactory.create(Type delegateType, IObject obj, string
methodName) is the bit I've already got)

Suggestions?

Cheers,

Thomas
