WebJun 12, 2012 · No, in 64-bit / C#, an int is still 4 bytes. In C#, int is always merely an alias to global::System.Int32 What will change is the reference size and pointer size, but that is all abstracted by the IL anyway - nothing needs to change. Note, though, that the CLI is only going to be 32 bit xor (nand?) 64 bit. WebJan 3, 2012 · @MatthewLock You should use UTF16 (or majidgeek's Length * sizeof (Char), which should give the same result since each Char is UTF16/2-bytes) if you want the same number of bytes as the internal representation of a string.

WebItems are stored in files as a sequence of bytes, so if you're worried about disk space you should use bytes. Items are processed by your CPU in 32- or 64-bit integers (depending on your processor) so any item that's less than that amount will be "upgraded" to a 32- or 64-bit representation for runtime computation. – Jake Feb 27, 2010 at 7:33 1 WebApr 7, 2024 · And that is true, a byte string is an array of 8 bits byte. There is not problems for bytes 0 to 127, but for example unsigned byte 255 and signed byte -1 have the exact same representation 0xFF in hexa. And there is no mean to guess whether that 0xFF is intended to be a 255 or a -1. signed_byte = signed.to_bytes (1, "little", signed=True ...
