How to generate Code 128B in C# .NET 4.5?

Question

C++ / C#

Good evening, dear colleagues.
Please help me with some C# code.
I am writing a small program for the needs of my organization, the task was to generate Code 128B, third-party DLLs are all paid, so I decided to look for a C # generation option, and found an example on Habré. the problem is that neither I nor my compiler understands the line:
Draw(ref g, code.output);
and
Draw(ref h, code.output);
no experience with graphics.
Tell me how to generate Code 128?
