I tried to send this question earlier, but it did not appear to go through.
Shortly after I tried to send it the first time, the "Consuming DynamicObjects
in IronRuby" thread popped up. It seems likely that the two issues are related,
but as my situation is a bit different and results in a different error
message, I thought it would be a good idea to resend this question. Note: I am
using .Net 4.0 RC and the "CTP for .Net 4.0 RC" release of IronRuby...
So I'm finally getting around to testing IronRuby/C# integration and hit a
stumbling block. Let's say I have the following class in Ruby:
class HandleMoveRequested
def handle(msg)
System::Console.WriteLine "Moving character to
" + msg.x.to_s + "," + msg.y.to_s + "."
end
end
As you can see it is a simple message handler that expects an object that has
an "x" and a "y" property. Now say I have the following C# code:
dynamic handler = ruby.handlemoverequest...@new();
dynamic msg = new ExpandoObject();
msg.x = 1;
msg.y = 2;
handler.handle(msg);
Creating the handler instance works fine, so I won't bore you with the details
of that, but for some reason the last line throws an InvalidOperationException
with the message "unbound variable: value". Everything works if the message is
a Ruby class that I create manually, but I'd love to be able to just create a
fully dynamic object (such as the ExpandoObject) here and pass it in. Is this
just not possible?
