How do I concatenate 2 bytes?

Question

I have 2 bytes:

byte b1 = 0x5a;  
byte b2 = 0x25;

How do I get 0x5a25 ?

Answer 1

The question is a little ambiguous.

If a byte array you could simply: byte[] myarray = new byte[2]; myarray[0] = b1; myarray[1] = b2; and you could serialize the byearray...

or if you're attempting to do something like stuffing these 16 bits into a int or similar you could learn your bitwise operators in c#... http://en.wikipedia.org/wiki/Bitwise_operation#Bit_shifts

do something similar to:

byte b1 = 0x5a; byte b2 = 0x25; int foo = ((int) b1 << 8) + (int) b2;

now your int foo = 0x00005a25.
