Question

I got an array which contains signed int data, i need to convert each value in the array to 2 bytes. I am using C# and i tried using BitConverter.GetBytes(int) but it returns a 4 byte array.

Answer 1

A signed 16-bit value is best represented as a short rather than int – so use BitConverter.GetBytes(short).

However, as an alternative:

byte lowByte = (byte) (value & 0xff);
byte highByte = (byte) ((value >> 8) & 0xff);
