Question

Given these integers:

public uint ServerSequenceNumber;
public uint Reserved1;
public uint Reserved2;
public byte Reserved3;
public byte TotalPlayers;

What’s the best way to create a byte[] array from them? If all their values are 1 the resulting array would be:

00000000000000000000000000000001 00000000000000000000000000000001 00000000000000000000000000000001 00000001 00000001

Answer 1

This should do what your looking for. BitConverter returns a byte array in the order of endianness of the processor being used. For x86 processors it is little-endian. This places the least significant byte first.

 int value;
 byte[] byte = BitConverter.GetBytes(value);
 Array.Reverse(byte);
 byte[] result = byte;

If you don’t know the processor your going to be using the app on I suggest using:

int value;
byte[] bytes = BitConverter.GetBytes(value);
if (BitConverter.IsLittleEndian){
Array.Reverse(bytes);
}
byte[] result = bytes;
