Assuming 32bit ints

So I read somewhere that int equals int32 in c#. Is it true also on 64-bit machines? Should I use int32 just to make sure no one at microsoft decides to change the size of int?

Answer 1

int is an alias for Int32

long is an alias for Int64

Their sizes will not change, at all, just use whichever one you need to use.

The use of them in your code is in no way related to 32bit and 64bit machines

EDIT: In reference to the comments about Thread Safety. Here is a good question and answers that detail any issues you need to be aware of. Under C# is Int64 use on a 32 bit processor dangerous
