Can two threads use same socket?

[selvialagar]

I'm explain my problem..

sockWriter=new Sender();
sockWriter->client =new TcpClient();
sockWriter->client->Connect(this->hostName,this->port_number);   
sockWriter->clientStream=sockWriter->client->GetStream();
localSocketWriter=new Sender(this->sockWriter->clientStream);

Thread *thread=new Thread(new ThreadStart(this,&platocomm::Listener));
			thread->Name =S"Listener";
			thread->Start();

here is the sender class members

                                                BinaryWriter *writer;
			TcpClient *client;
			NetworkStream *clientStream;
			static StreamWriter *fileWriter;
			Sender(NetworkStream *clientStream);

now i use the Listener to read data from the transport connection. My question is, can i use another thread , to read the data from the same trasport connection. When i tried this, it shows "a socket can not be accessed in a way forbidden by its access permissions". how to make this possible...plz suggest some solution for this..

I've got a similar example for you below demonstrating how to go about it. Obviously however you'll not be using Binary Readers/Writers, and it looks like you're coding in C++, but it should get you there...

namespace Server  
 {  
    public class Server : System.Windows.Forms.Form  
    {  
       private Socket connection;  
       private Thread readThread;  
       private NetworkStream socketStream;  
       private BinaryWriter writer;  
       private BinaryReader reader;  
   
       public Server()  
       {  
          ...  
   
          // create a new thread from the server  
          readThread = new Thread( new ThreadStart( Run ) );  
          readThread.Start();  
       }  
   
       // allows a client to connect and displays the text it sends  
       public void Run()  
       {  
          TcpListener listener;  
   
          try  
          {  
             // Create TcpListener and wait for connection  
             listener = new TcpListener( 5000 );  
             listener.Start();  
   
             while ( true )  
             {  
                // Accept an incoming connection  
                connection = listener.AcceptSocket();  
   
                // create NetworkStream object associated with socket  
                // and writers/reader for data transmission  
                socketStream = new NetworkStream( connection );  
                writer = new BinaryWriter( socketStream );  
                reader = new BinaryReader( socketStream );  
   
                // inform client that connection was successfull  
                writer.Write( "SERVER>>> Connection successful" );  
   
                string theReply = "";  
   
                // Read String data sent from client  
                do  
                {  
                   try  
                   {     
                      theReply = reader.ReadString();  
                   }  
                   catch ( Exception )  
                   {  
                      break;  
                   }  
   
                } while ( theReply != "CLIENT>>> TERMINATE" && connection.Connected );  
   
                // Close connection  
                writer.Close();  
                reader.Close();  
                socketStream.Close();  
                connection.Close();  
             }  
          }  
          catch ( Exception error )  
          {  
             MessageBox.Show( error.ToString() );  
          }  
   
       }  
    }
