Receive multiple response from client error using TCP in C#

Question

So I was trying to make a code where TCP will accept all client which involves the repeat accept client but when I use that, I cant receive any response from the client so how do I solve this?

The messagebox won't even pop up on the server

code for the buffer location (Background worker):

while (true)
{
            try
            {
                client = network.AcceptTcpClient();
                streamer = client.GetStream();
                buffer = new byte[client.ReceiveBufferSize];
            } catch(Exception ex)
            {
                MessageBox.Show(ex.Message,"Client Connection Error");
                client.Close();
                streamer.Close();
                Close();
            }
        }

Code where ill show messagebox when client send a response back to the server (Background worker):

private void backgroundWorker2_DoWork(object sender, DoWorkEventArgs e)
    {
        BackgroundWorker worker = sender as BackgroundWorker;
        while (true)
        {
            string data = Encoding.Unicode.GetString(buffer, 0, 
streamer.Read(buffer, 0, client.ReceiveBufferSize));
            if (data == "Response_Command_329873123709123")
            {
                int slowdown = streamer.Read(buffer, 0, 
client.ReceiveBufferSize);
                var message = Encoding.Unicode.GetString(buffer, 
0,slowdown);
                worker.ReportProgress(0, message);
            }
        }
    }
    private void backgroundWorker2_ProgressChanged(object sender, 
 ProgressChangedEventArgs e)
    {
        MessageBox.Show((string)e.UserState, "Client Response");
    }

Here is part of the code where client receives a response from server then send a server a message (Part of the code but mainly focus on this):

else if (data == "Messagebox_Command_2837190092703817203")
            {
                int txtbox = streamer.Read(buffer, 0, 
client.ReceiveBufferSize);
                string txt = Encoding.Unicode.GetString(buffer, 0, txtbox);
                MessageBox.Show(txt, "Message From Server");
                byte[] database = 
Encoding.Unicode.GetBytes("Response_Command_329873123709123");
                streamer.Write(database,0,database.Length);
                byte[] databases = Encoding.Unicode.GetBytes("test");
                streamer.Write(databases, 0, databases.Length);

Answer 1

I think my buffer part error but i fixed it

int databases = streamer.Read(buffers, 0, buffers.Length);
                string data = Encoding.Unicode.GetString(buffers, 0, databases);
                if (data == "Response_Command_329873123709123")
                {
                    byte[] datacen = new byte[client.ReceiveBufferSize];
                    int main = streamer.Read(datacen, 0, datacen.Length);
                    var message = Encoding.Unicode.GetString(datacen, 0, main);
                    MessageBox.Show(message, "Client Response");
                }
