How to convert int array to byte array?

Question

C++ / C#

array int[]? Whether it is possible to transform in one action, instead of each element to read. An array is just a region in memory. Changing the type, I don’t change anything, the same 4 bytes remain in the same place.

Answer 1

Maybe something like.

var array = new[] {1, 2, 3, 4};
var span = new Span<int>(array);
var bytes = MemoryMarshal.AsBytes(span);
var byteArray = bytes.ToArray(); //тут будет копирование.

If copying is undesirable, then you can try using pointers and unsafe.

Answer 2

I'm certainly a noob but maybe this will help
