Thread: integer type in C#

1: Correct
2: int is int32 http://msdn2.microsoft.com/en-us/lib...5w(VS.80).aspx

The difference between int and int32 is that int32 is GUARANTEED to be 32 bits, whilst for example a future compiler may decide that int is better off being a 64-bit integer (for example because those are handled FASTER than 32-bit integers in that model of machine).

So if you have a situation where you want the size to be precise, use int32 or int64. If you just need "some integer that works for 32-bit or larger numbers", then use int.

The situations where you need defined sizes are when you communicate outside your own unit, for example in sockets, files and such, or talking to hardware registers [unlikely in C#, but as a general rule it applies], modules that are outside of your source control (DLL's for example).

Not in the Net environment, as I understand - there the type lengths are fixed across all compilers, languages and OSes that support Net - ensure that all remote procedure calls (around language, comps, OSes boundaries) will succeded
