MCR .Net using Native Dll, data type unsupported by matlab

Hi there.

i have a MATLAB function that returns a struct (Instace) and a string (Json)

function [Instance,Json] = Process(path)    
% Some Work
end

i am compiling this function into .Net dll and taking the native.dll file.

then i run this function from c#, and i get this error

"Data type unsupported by MATLAB .NET Assembly for conversion to array"

which means that the MCR can't convert the struct (Insrance) into a .Net object.

if i remove the struct (Instace), it works fine.

Q:

is there a way to ignore this parameter?, without returning just the Json.

it need to return both of them.

i don't need it just the json.

Thanks!

@Daniel,

I found in the documentation that MATLAB Compiler SDK supports converting MATLAB structures to managed .NET types using MWStructArray.

I think you are able to compile the MATLAB function into .NET DLL successfully, but getting an error while running it from C#. Can you share the code snippet of the MATLAB and C# so that I can try reproducing it?
