Should I use int or UInt16?

Question

This may be somewhat trivial, but in C# do you prefer int or UInt16 when storing a network port in a variable? Framework classes use int when dealing with a network port although UInt16 actually represents the valid values.

Answer 1

signed (int / short etc, rather that uint / ushort) have the advantage of being CLS compliant, so that is recommended unless you have a good reason.

Re int vs short - in most cases it is more efficient to compute with int (or uint), since all the operators are optimised for this. If you are only storing and retrieving it then this isn't an issue, of course.
