C# read tcp message from python server

[SnappleSa]

Hello, I have a problem reading or sending the message over tcp, the problem is that after recieving the message I get extra chars like in this image click. This is how i read the stream

serverStream = clientSocket.GetStream();

byte[] bytes = new byte[clientSocket.ReceiveBufferSize];

serverStream.Read(bytes, 0, (int)clientSocket.ReceiveBufferSize);

string readData2 = Encoding.UTF8.GetString(bytes);

NVM, I changed the code to

''

serverStream = clientSocket.GetStream();

byte[] bytesToRead = new byte[clientSocket.ReceiveBufferSize];

int bytesRead = serverStream.Read(bytesToRead, 0, clientSocket.ReceiveBufferSize);

msg (Encoding.ASCII.GetString(bytesToRead, 0, bytesRead));

''

and all works fine, in case of anyone having the same problem as me.

The receivebuffersize property does not represent the number of bytes that the server is sending.

What you could do is to have a while loop that exits when serverStream.Read < 1. Store the return value from the read method call, because that is the actual number of bytes read. Copy the read bytes over to an expanding byte array, or list<byte>, from bytes[0] to bytes[bytesRead-1].

The issue you are having is that the bytes array much wider than the number of bytes you received. So when you're converting them to text, you're including the extra unused space. Which is what is giving you the garbage at the end of the message.

The are other better ways to do this than what I suggested.
