My guess is that something like this must exist in the framework but I can't find it where I expect it to be:)
I would like a function to return a subset of a byte array (similar to what Substring() does for a string).

Something like this:

byte[] ba = new byte[100];
byte[] subba = ba.Subbytearray(3, 10); // starting at index 3 and returning 10 elements

Since I can't find Subbytearray, I use the following code:

byte[] ba = new byte[100];
byte[] subba = new byte[100];
subba = Array.Copy(ba, 3, subba, 0, 10);

Thanks,
Einar
