The C# wrapper could be as simple as:
public static class MyWrapper {
public static void IServerInterfaceMethod(object o) {
((IServerInterface)o).IServerInterfaceMethod();
}
}
Used like:
MyWrapper.IServerInterfaceMethod(TransparentProxy)
If you just want to call all static methods, or you can make an instance
wrapper:
public class MyWrapper {
private readonly IServerInterface _wrapped;
public MyWrapper(object wrapped) {
_wrapped = (IServerInterface)wrapped;
}
public void IServerInterfaceMethod(object o) {
_wrapped.IServerInterfaceMethod();
}
}
Used like:
MyWrapper(TransparentProxy).IServerInterfaceMethod()
Then you can pass around the wrapper object and just use it like a normal
object. If you need to get back to the transparent proxy for some reason you
could add a property which returns it.

The clr.Convert(TransparentProxy, IServerInterface) is failing with same
exception
I will code a C# wrapper but what does it mean? A client side assembly that
will get the transparent proxy and convert it to the Interface type I need?

Hurm, maybe this is a different problem then... Does:
import clr
clr.Convert(TransparentProxy, IServerInterface).IServerInterfaceMethod()
work?
If not then my guess is you might need a C# wrapper :(

Subject: RE: .NET Remoting and Interface based objects
I tried using typedproxy class
Not sure I am using it the right way
This is what I did
test = typedproxy(TransparentProxy, IServerInterface)
test.IServerInterfaceMethod()
This call is failing with "Expected IServerInterface, got MarshalByRefObject"
I debugged the code to find out where it is failing, it is in typedproxy (I
marked the line)
class typedproxy(object):
__slots__ = ['obj', 'proxyType']
def __init__(self, obj, proxyType):
self.proxyType = proxyType
self.obj = obj
def __getattribute__(self, attr):
proxyType = object.__getattribute__(self, 'proxyType')
obj = object.__getattribute__(self, 'obj')
att = getattr(proxyType, attr)
att2 = att.__get__(obj, proxyType) #This line is throwing the exception
return att2
Any idea?
Thank you very much;

I'm not quite certain this is the same issue but you should try using the
wrapper from this thread:
http://lists.ironpython.com/pipermail/users-ironpython.com/2006-September/003549.html
The transparent proxies always succeed when casting them to an interface type
so it's hard for us to work w/ the objects when we need to check for certain
interfaces ourselves.

Subject: [Ironpython-users] .NET Remoting and Interface based objects
Hi,
I am trying to call our .NET service via remoting using IronPython
I have the transparent proxy object but I don't know how to cast it to the
interfaces (that are implemented by the server side object)
I tried IServerInterface.SomeMethod(transparent-proxy-object) but it is failing
with "expected IServerInterface, got MarshalByRefObject"
How can I cast it to an interface?
I am using 2.7
Thanks in advance,
Tsahi Muyal
