I'm pretty sure you can't do this. You have to be able to translate the C++ code directly to a C# class, so you would at least have to replicate the internals of the vector class to marshall it correctly. I'm also pretty sure you won't be able to move references across the boundary, you'll have to use IntPtr (raw pointers). The approach that i know works is to marshall a raw array of the structs.
