[RESOLVED] TCP client issue

[Krotcha87]

Hello. I am using a TCP client to send and receive data, but for some reason the data it receives has a bunch of white spaces at the end of each message.

    System.Text.StringBuilder income_message_client = new System.Text.StringBuilder();

    void Manage_Connection_Client()
    {
        do
        {
            int read;
            do
            {
                byte[] bytes = new byte[client.ReceiveBufferSize];
                read = client.GetStream().Read(bytes, 0, bytes.Length);
                income_message_client.Append(System.Text.Encoding.UTF8.GetString(bytes));
            }
            while (read == 0);
            //do things based on data received
        }
        while (true);
    }

The data I receive is: "Blablablabla123 (space) (space) (space) (space) (space) (space) (space) (space) (space)", while the data I send truly is "Blablablabla123"
(space) = " "

You are creating a buffer of a particular size and then writing the data received into that buffer, but the data received is not necessarily enough to fill that buffer. You then convert the entire buffer to a String, so you're also converting the portion of the buffer that wasn't filled. The Read method returns a number that represents the number of Bytes read. The whole point of that value is so that you know how many Bytes of the buffer to use. You have used a variable named 'read' to store that value. When you convert the data received to a String you need to use that value to specify how much of the buffer to convert.

Thanks a lot, jmcilhinney.
You were right, it turns out all I had to do was change this line:

income_message_client.Append(System.Text.Encoding.UTF8.GetString(bytes, 0, read));

Thanks very much again!
