Hi,
I'd like to call a managed method from c which returns a GLib.List.
I seem to be unable to do this, however..
my managed code looks like:
public GLib.List Test()
{
GLib.List list = new GLib.List(typeof(string));
list.Append(eins);
list.Append(zwei);

What you are getting back is not a pointer to the C GList, but a pointer to
the managed GList; What you need to do is return the unmanaged pointer
that is wrapped by the C# GList, that would be the
Print out the value of the 'Handle' property in your c# code before the
method returns and then print the value you get in native after you unbox.
If they're not the same value you're done something wrong. Give that a shot
and see what happens. Maybe it'll help you diagnose the issue.

You must unbox the returned object. See mono_object_unbox().

Yes, I tried that, too.
The code looks like this:
MonoObject *o = mono_runtime_invoke (method, instance, NULL,ex);
GList *list = (GList

mono_object_unbox() returns a pointer to your intptr, so you
have to dereference it:
GList *list = *(GList**)mono_object_unbox (o);
Thank you, Robert - you are amazing!!
And I definitively have to read up on the usage of pointers - and on
how many
