My understand was that int was just a language keywrod and when a compiler in a 32-bit OS sees int, it actually uses System.Int32, and a 64-bit OS actually uses System.Int64.
Oh and for that
vs
Code:
int a;
int b;
int c;
Those are the same, the only time this might make a difference is when you are compiling, but the same IL code should be generate.
And it looks like the first two replies to that post are correct in what they say...
