The length of the arrays should not cause any problems to Array.Copy; e.g.
the following copies the second 50 bytes of a 100 byte array into (roughly)
the middle of a 500 byte arraym then prints some of the contents to validate
this.
byte[] source = new byte[100];
for (int i = 0; i < 100; i++)
source[i] = (byte) i;
byte[] dest = new byte[500];
Array.Copy(source, 50, dest, 200, 50); // source array, source
start-offset, destination array, destination start-offset, items to copy
for (int i = 195; i < 255; i++)
Console.WriteLine("{0}: {1}", i, dest[i]);
If you are going to copy the entire source array, source.CopyTo(dest,offset)
is an easier option - again, it doesn't need the arrays to be the same size,
as long as there is sufficient space in the destination.
Did I miss something in your question?
