Hmm, so I have:

class MyClass
     List<int> a;

I iterate through it from c code and use mono_class_get_fields,  

Then i do mono_object_new and call mono_runtime_object_init on it.

Are you sure this should work? It generates an invalid object for me.  
Is it possible that using System.Activator.CreateInstance  will  work  
better or does this internally do the exact same thing?
