Naming convention - underscore in C++ and C# variables

Question

It\'s common to see a _var variable name in a class field. What does the underscore mean? Is there a reference for all these special naming conventions?

Answer 1

You can create your own coding guidelines. Just write a clear documentation for the rest of the team.

Using _field helps the Intelilsense to filter all class variables just typing _.

I usually follow the Brad Adams Guidelines, but it recommends to not use underscore.
