TCPListener and string formatting problems

Hi
I need a TCPListener and a TCPClient to communicate correctly
TCPListener sends this

string strData = "ABC"
byte[] data = Encoding.ASCII.GetBytes(strData)
s.Send(data, data.Length,0)

TCPClient receives
Byte[] read = new Byte[32]
String Data = Encoding.ASCII.GetString(read)

When I print the result in a textBox/messageBox it look like this: ABC
but if I try to test i
if(Data=="ABC"


it never works

I believe it has to do with the string -> charArray -> byte[] -> string formatting, but can't figure it out..
Please help
Thanks

If you are open to using open source comonents, there is a TCP client /
server demo here:

which demonstrates what you are trying to do.

Well, you haven't really shown how you've read the data - you've shown
creating anew byte array, but not how the data gets into it. The
problem may well be that your byte array *is* 32 bytes long, even
though you've only read three bytes of data. You're then decoding all
32 bytes, so you've got a string with ABC and then 29 null characters -
which isn't the same as the string "ABC".
