Is this modular programming?

Question

I have a question here - in C# - the partial class , and in VB.NET the Module - are they part of modular programming as wiki describes it?
partial class is defined as a class that have multiple implementations across all namespaces that have it, and it "assembles" on execution.
(BTW, part of modular programming are also interfaces - which is maybe the same?)

Answer 1

Modular programming is not language specific and is more of a coding methodology. The modifiers of classes cannot, themselves, make classes modular. I would suggest reading up on SOLID coding principles to get a better idea of what makes code modular.
