Question

First: Excuse me if the question is wrong, I don’t really know how to describe it since I’m not a pro on coding terms.

So I have written this line in the main class:

    public Log log = new Log("program.log");

Which starts a session of my logger. I then use that session to write to the log everywhere in my main class code.
But I am doing the dirty work in another class, so I want to log there too. How do I access the same “log session” from that class?

Writing MainClassName.log doesn’t work.

No, MainClassName.log won’t work because your variable is an instance variable. It would need to be a static variable… or you’d have to have an instance of MainClassName through which to access the instance variable.

However, personally I’d advise you not to use public variables at all. I would suggest using private variables for everything other than “constants” (where that can be a readonly variable of an immutable type, not just something that .NET considers a constant) – and even then in many cases.

I would also suggest the use of something like log4net – and you’re likely to benefit from using a separate logging object per class, so that you can easily switch logs from different classes on or off (or use even more fine-grained control with severities).
