I want to add two byte array in window application.
byte[] b1;
byte[] b2;

I want to do:-

How can i do this process with byte array.
I am use this:

for (int i = 0; i <b1.length;>{
b2[posoftotaldata] += b1[i]; // posoftataldata is define globally and static
But in this i don't get exact size of b2 because i also defined b1 and b2 globally how i define dynamically size of b2.
This work properly but confusion in size.

A simple way to achieve this is to use a generic list and use the AddRange method to add the byte arrays together - the list allows you to output the data as an array, so you would get a byte array out. Here's an example:
private byte[] GetBytes(byte[] b1, byte[b2])
  List<byte> data = new List<byte>();
  return data.ToArray();
There are many ways to achieve the same effect, but this is a simple, easy to debug version.

I want to do this process in class file and in class file i don't get List.

You need to add using System.Collections.Generic to get access to the generic list.

What is "in class file"?! What does it mean "I don't get list"? What and how you wanted to "get" it?
