c# - Socket receive does not release the buffer (byte array) -

i'm developing service listens messages in tcp protocol, , send them different destinations.

so defined socket , stays open time , gets messages . size of protocol static , messages arrive few @ time.

the loop runs long values received , cuts matching size of messages.

the service works well- messages received needed memory gets , up. implementation:

public void waitingforclient() {     while (true)     {         // accept block until connects         m_socket = m_tcplsn.acceptsocket();         threadpool.queueuserworkitem(new waitcallback(readsocket));     } }  //read data socket public void readsocket(object obj) {     socket s = m_socket;      if (s.connected)     {         byte[] receive = new byte[message_length];         try         {             // receive block until data coming             // ret 0 or exception happen when socket connection broken             int ret = s.receive(receive, receive.length, 0);             while (ret > 0)             {                 onmessagerecieved(new recievedmessage(receive));                 **receive = new byte[message_length];**                 ret = s.receive(receive, receive.length, socketflags.none);             }         } 

i saw in net memory profiler buffer(a byte array defind in loop), never gets freed , therefore there problem of memory leak. in every sending of message instanse of byte array created & nothing freed.

i tried write loop initializes array in nulls way:

try {     // receive block until data coming     // ret 0 or exception happen when socket connection broken     int ret = s.receive(receive, receive.length, 0);     while (ret > 0)     {          onmessagerecieved(new recievedmessage(receive));          (int = 0; < message_length; i++)          {              receive[i] = 00;          }          ret = s.receive(receive, receive.length, socketflags.none);     } 

but part of messages sent nulls instead of right values(messages joined together).

how can solve it?
