[2.0] Remove null bytes from an array?

[high6]

I have

byte[] buf = new bytes[256];
                bytesrec = TCP.Client.Receive(buf,System.Net.Sockets.SocketFlags.None);

But the problem is when there is a packet sent with less then 256 bytes it has empty bytes on the end. How do i format it to remove those bytes?

Hi, I had an old project that used Byte arrays alot, I seem to remember something like you can prefix bytes with a *, ie.

*bytes

And it will create the array members as you need them.

I don't know if it was that exactly, and I don't know if you're using 256 for a reason (limit size)?

Either way, hope that helps, I'll try to find that project to show you better, more usefull code.

You don't remove them. A byte array with 256 elements has 256 bytes in it. The idea is that the 'bytesrec' variable contains the number of btes that were actually received. You use that number to know how many elements of the array to actually use. If 'bytesrec' is 256 you know the array is full, otherwise you only use the first 'bytesrec' elements. If you need a full array for some reason then you have to create a new byte array with 'bytesrec' elements and then copy the first 'bytesrec' elements from the original array.
