Question

I have an array, i don’t know the length but i do know it will be >=48bytes. The first 48bytes are the header and i need to split the header into two.

Whats the easiest way? I am hoping something as simple as header.split(32); would work ([0] is 32 bytes [1] being 16 assuming header is an array of 48bytes)

using .NET

I decided to write something. It could be nicer like a extended function but it is good now.

    Byte[][] SplitArray(byte[] main, params int[] size)
    {
        List<Byte[]> ls = new List<byte[]>();
        int offset = 0;
        foreach (var v in size)
        {
            var b = new Byte[v];
            Array.Copy(main, offset, b, 0, v);
            ls.Add(b);
            offset += v;
        }
        {
            var b = new Byte[main.Length-offset];
            Array.Copy(main, offset, b, 0, b.Length);
            ls.Add(b);
        }
        return ls.ToArray();
    }
