I have all the data for my application loaded into memory already so holding the DateTime object in memory is not up for debate
I disagree, and not to be rude, but I truly think it is up for debate , unless you're absolutely willing to reject any evidence and advice given by others in this thread, I have a hard time believing that you're storing more than 70 000-100 000K in memory just for your one program... If you do, then there's something you're doing which is seriously wrong. Either way, storing ONE DateTime object in memory as a reference will NOT hurt anything.
You seem to be worried about memory usage for your application. I can honestly say that storing a DateTime object vs. instantiating a whole FileStream will be less of a burden on memory here.
You misunderstood the data I was saving and how I was saving it.
Good thing C# has garbage collection right?
Check out the app I am making here
No, I understood how you were saving it, but I misunderstood what data you were saving other than a DateTime object because you did not clearly specify the full scope of your program. Yes C# has GC, but understanding when and what it cleans up is important. If you assume it'll do everything for you, you'll have a heck of a time optimizing programs when managing unmanaged resources... This is what i'm trying to explain to you. You need to also make sure that you're properly disposing of your objects which implement the IDisposable interface. (Specifically from what I can assume about your program; objects that use FileStreams. Don't forget!)
lol, read what i've posted!
I'm not here to battle you, the reason why I joined the discussion in this thread was to help you. Please do not misinterpret that. If you take my advice for what it is, I have good reason and intention for why I say what I do. Those who keep a closed mind, won't learn much more than they already know. It's good to learn from others, and I do have some experience that I enjoy sharing with others, if they so choose to accept my words; suggestions, recommendations, and other advice.
