How to pass a c++/CLI ref class as a function parameter

Question

I have a c++/CLI ref class called LFSparams in my visual c++ code. I want to pass an object of this class as a function parameter: (I get the LFSparameters object as a function parameter from c# code)

lfsparms actual_lfsparms = Convert2lfs(LFSparameters);

but VS says: " "Nbis::LFSparams" has no suitable copy constructor"

The problem is, there is no way to create a copy constructor for a reference class, also I can not pass the object by reference, because it is already a reference.

So how can I pass this object as a parameter?
