[RESOLVED] Datatype size on 64-bit systems.

I'm still using ye ancient 32-bit machine with ye olde XP.

Currently I'm writing some code to add binary content to files, and I need to know, if the same code can be applied on 64-bit systems.
For example an integer variable added to a binary file with:

Code:

---

BinaryStream.Write(SomeNumberDeclaredAsInteger)

---

can be safely loaded with

Code:

---

MyInteger = BinaryStream.ReadInt32

---

on my system, but is this also the case on 64-bit systems or should I truncate it to Int32 before writing it to file?

Thanks in advance for any help with this

According to MSDN, the Integer datatype is equivalent to System.Int32. And as the name implies, System.Int32 will be 32 bit on both 32-bit and 64-bit systems.
This would mean that your code will work alright on a 64-bit system aswell.

The thing that changes size between 32-bit and 64-bit systems is an IntPtr. It basically represents a memory address, so it will be as wide as that needs.

Big thanks to both.

Thread resolved!
