Ok, this is probably highly subjective but here it comes:

Let’s assume I’m writing a method that will take a printscreen of some region of the screen. Which method signature would you prefer and why?

  1. Bitmap DoPrintScreen(int x, int y, int width, int height);
  2. Bitmap DoPrintScreen(Rectangle rect);
  3. Bitmap DoPrintScreen(Point point, Size size);
  4. Other

Why?

I keep seeing myself repeatedly implementing both 1) and 2) (redirecting one of them to the other) but I end up usually just using one of them, so there really is no point in having both. I can’t decide which would be better. Maybe I should use the signature that looks the most with the method I’ll be calling to make the printscreen?

    The best one is

    Bitmap DoPrintScreen(Rectangle screenArea);

    If you think about the method parameters as being part of a “concept”, in this case the concept of a screen area, then the other options don’t abstract that concept nicely enough.

    Also, use a good name for the parameter, because it might make calling code even more clear by the use of named parameters in C# 4.0.
