Use a list and add each array using AddRange then convert back to an array
List<byte> list = new List<byte>();
list.AddRange(a);
list.AddRange(b);
 
byte[] c= list.ToArray();

I am talking about byte[] not byte

That was my understanding of your question ...that's why the solution posted produces a byte[]

Hi Faisalabadians.

about the solution of CHill60 - nice & simple (you got my 5+)

If performance is important and if you can use an IEnumerable<byte>, definitely prefer Linq's Concat<> method.

IEnumerable<byte> Con_A_and_B = a.Concat(b);

Cheers,
Edo

My 5! That's also like I would do it (I would even use var, but that is debatable for many here... ;-)).
Cheers

You're getting my +5 for this as well - about time I did more with Linq. Oh the joy of working with legacy versions of tools ;-p
