tcp - Synchronization in C# networking -

i have simple tcp server class

 class server {     private tcplistener tcplistener;     private thread listenthread;      public server()     {         this.tcplistener = new tcplistener(ipaddress.parse("127.0.0.1"), 3000);         this.listenthread = new thread(new threadstart(listenforclients));         this.listenthread.start();         console.writeline("hello");     }       private void listenforclients()     {         this.tcplistener.start();          while (true)         {             //blocks until client has connected server             tcpclient client = this.tcplistener.accepttcpclient();              //create thread handle communication              //with connected client             thread clientthread = new thread(new parameterizedthreadstart(handleclientcomm));             console.writeline("new connexion");             clientthread.start(client);         }     }      private void handleclientcomm(object client)     {         tcpclient tcpclient = (tcpclient)client;         networkstream clientstream = tcpclient.getstream();          console.writeline("got stream");          byte[] message = new byte[4096];         int bytesread;          console.writeline("initializing..");         while (true)         {             bytesread = 0;              try             {                 //blocks until client sends message                 console.writeline("reading..");                 bytesread = clientstream.read(message, 0, 4096);                 console.writeline("received something");             }             catch             {                 //a socket error has occured                 break;             }              if (bytesread == 0)             {                 //the client has disconnected server                 break;             }              //message has been received             asciiencoding encoder = new asciiencoding();             console.writeline(encoder.getstring(message, 0, bytesread));          }          tcpclient.close();     }  } 

i call in main function :

server server = new server(); 

and in separate client program have class

class theclient {   public void connectv2()     {           tcpclient client = new tcpclient();          ipendpoint serverendpoint = new ipendpoint(ipaddress.parse("127.0.0.1"), 3000);          client.connect(serverendpoint);          networkstream clientstream = client.getstream();          asciiencoding encoder = new asciiencoding();          (int = 0; < 20; i++)         {              byte[] buffer = encoder.getbytes("hello server! " + i.tostring() + " ");              console.writeline("processing..");              clientstream.write(buffer, 0, buffer.length);             clientstream.flush();             console.writeline("hello server sent");         }       }  } 

i call in main function like

theclient tc = new theclient();  tc.connectv2(); 

my problem server program seems slower client, don't react before 13th, or more, message client :

[i can't post images because of reputation]

it reads first dozen of messages in 1 go, , reads others 1 one.

and if make server emit first, client receive message, both stop, if both wait other send something.

can explain me behavior ? how can control , synchronize ?

tcp not message based. provides stream of bytes. responsibility separate messages. note, might receive part of message in 1 read call.

here's simple way that: send messages individual lines. possibly using streamwriter. receive messages using streamreader.readline().

that way can use more sane encoding such encoding.utf8.

besides code fine , workable. extremely rare see working tcp code on stack overflow. code horribly broken. congratulations.
