OK nigger, don't use a fucking Hashtable. You want Dictionary<byte, List<byte>>
Dictionary implements a hashtable for lookups. Hashtable is for fags because it boxes and unboxes everything as object, which will add conciderable overhead for your fucking bytes (this isn't Java you faggot [even Java generics box and unbox everything as object because it was made by idiots]).
var fagtionary = new Dictionary<byte, List<byte>>();
fagtionary.Add(255, new List<byte>() { 1, 2, 3, 4, 5 });
fagtionary[255].Add(6);
Console.WriteLine(fagtionary[255][fagtionary[255].Count - 1].ToString());
Outputs: 6

For fucks sake nigger. char is not a byte, if it was they would call it byte and not char. A char is 2 bytes.
