Answer 1

You may take a look at the GetBytes method:

int i = 2200;
byte[] bytes = BitConverter.GetBytes(i);
Console.WriteLine(bytes[0].ToString("x"));
Console.WriteLine(bytes[1].ToString("x"));

Also make sure you have taken endianness into consideration in your definition of first byte.

Answer 2

byte[] bytes = BitConverter.GetBytes(2200);
Console.WriteLine(bytes[0]);
