C#: How do I instantiate a class in C#, like showin this C++ example -
i've translated following c++ code c#, cant determine , how put class instance. if using:
customanalysis test = new customanalysis(); it receive errormessage, telling me class instantiated rhino3d, , therefore i'm not supposed it. need create reference class can it's static member m_am_id variable created base-class.
this line im having trouble with:
static class czanalysisvam thezanalysisvam; thanks in advance.
c++ code:

if need static member of customanalysis class in c#, can access customanalysis.m_am_id. since member static, access using class itself, not object of class.
