Hi @Shuhua
Perhaps we could merge some of our work together?
Here is my interop library: Interoperability with .NET - #21 by HyperSphereStudio
It provides interop from C# to Julia and Julia to C# (Julia → C# is far more primitive atm though).
I see you have some C interface backend, I have been working on the frontend as well if you want to take a look. Mind if I use some of your work for my JLArray etc?
