Add reference ?

Unity Engine
1

I am trying to add System.Drawing reference to my project. I found that System.Drawing.dll is used.
So I dragged this dll to assets of my project, sync and used it.
In game view everything works, but when I am building my project it does not work. Is there any correct ways of adding references?

Thank you in advance.

You must copy the assembly into the project before building it. Unity won’t copy non-standard assemblies for you
