arrays - How to convert a sbyte[] to byte[] in C#?

Question

I've got a function which fills an array of type sbyte[], and I need to pass this array to another function which accepts a parameter of type byte[].

Can I convert it nicely and quickly, without copying all the data or using unsafe magic?

Answer 1

Yes, you can. Since both byte and sbyte have the same binary representation there's no need to copy the data. Just do a cast to Array, then cast it to byte[] and it'll be enough.

sbyte[] signed = { -2, -1, 0, 1, 2 };
byte[] unsigned = (byte[]) (Array)signed;
