[Mono-list] how to "register" a c++ class to c#?

[=?GB2312?B?0rG+p7XL?=]

hi,dear all:
  i'm an absolutely newbie to mono. when i'm working with lua and python, i
often write many c++ classes to implement some core logic, then "register"
them to script. in lua, its metatable can be used for simulating the class
mechanism. in python, there's a builtin type system and corressponding c api
for this. then what should i do if i want this to work in mono c#? where can
i find some samples or tutorials? thanks very much!
