You are right, you cannot resize an array. You can copy a range of bytes from one array into a new array (see Array.Copy()), but that requires 2x the memory.
Adam may be right - depending on your needs - a MemoryStream may be the best choice for size and perf. The downside of a MemoryStream is that it's a little less direct to read from and write to.
