Selecting part of an array to write into

Question

I'm building up a composite of a number of byte arrays. I'd like to do this quickly but looking for a smart way of doing this:

uint A = 1000;
uint B = 2000;

Key[0:3] = BitConverter.GetBytes(A);
Key[4:7] = BitConverter.GetBytes(B);

I cannot see an easy way to do this. I do not want to use LINQ. Where BitConverter.GetBytes(A) returns 4 bytes. Of course I can do 16 assignments but this is messy. Is there any good looking syntax that is fast?

That's not the exact duplicate. This one possibly asks for list(array) manipulation in range-based manner, and not just about how to copy array parts. — Eugene Podskal, Jun 27 '14 at 16:04

Use the Array.Copy method for each of the GetBytes() result.
