Reading from an SystemArray into an ArrayList???

HI im trying to read from an array into an arraylist but it keeps on throwing an outofbounds exception,

Numbytes= 1
byte[] BufBytes;
ArrayList allBytes = new ArrayList();

while(count != 0)

                              ReadFile(hComm, BufBytes,NumBytes,ref BytesRead, zero);
                              count = BytesRead;
                        allBytes[i++] = BufBytes[0];

Well the most obvious things is you need to use allBytes.Add - you've created an ArrayList but not actually made any space within the ArrayList

Hope this helps
Also why do you assigne only the first (with index 0) byte to the ArrayList. And why do you assign the BytesRead to the count variable - just use the BytesRead.
