Does it really matter to distinct between short, int, long?

Question

In my C# app, I would like to know whether it is really important to use short for smaller numbers, int for bigger etc. Does the memory consumption really matter?

Answer 1

Only you can be the judge of whether the memory consumption really matters to you. In most situations it won't make any discernible difference.

In general, I would recommend using int/Int32 where you can get away with it. If you really need to use short, long, byte, uint etc in a particular situation then do so.
