c# - Parse the received message from the server -

the problem i'm having parsing bytes i'm reading through server client's interface , show them message received.

the general idea send message, message goes server , send message clients connected chatroom.

but happens when enter chat room message appears ">>ignusername" mark new user has entered chat.

and when try send message such "hello" server receives messages correctly when it's time send message users appears on screen ">>ignusername". original message. i'm not sure faulty extract of code fix issue i'm having.

conn.server.beginreceive(dat, 0, 1024, socketflags.none, new asynccallback(recibiendof), so);  if (//something has been received) {     mensajenuevo = msjerecibidof(dat); } 

this callback

public void recibiendof(iasyncresult ar) {     try     {         stateobject = (stateobject)ar.asyncstate;         conn.server = so.worksocket;          int bytesread = conn.server.endreceive(ar);          if (bytesread > 0)         {             string mensajote = system.text.encoding.ascii.getstring(mensajenuevo);             if (textbox_curmsg.invokerequired == true)             {                 this.textbox_curmsg.begininvoke((methodinvoker)delegate                 {                     textbox_curmsg.text = mensajote;                 });             }             else                 textbox_curmsg.text = mensajote;             //recibemsje();         }         else         {             if (so.sb.length > 1)             {                 string response = so.sb.tostring();             }             //recibemsje();         }     }     catch     {     } } 

and function wanted use before using callback

public byte[] msjerecibidof(byte[] msej) {     byte[] mensajeiro = new byte[1024];     mensajeiro = msej;     mensajenuevo = msej;     return mensajeiro; } 

conn.server.beginreceive(dat, 0, 1024, socketflags.none, new asynccallback(recibiendof), so);  if (//something has been received)                  {                     mensajenuevo = msjerecibidof(dat);                 } 

this not how work. using asyn receive method returns immediately. callback called when actual receive happens. method msjerecibidof(dat); passed empty dat or , older data.

also, @ end of public void recibiendof(iasyncresult ar) have call onn.server.beginreceive again receive next message.

because have posted part of codes, best can answer. fix these , see...
