Something like this ought to do you, though I'm sure I'm missing a ton of exceptional condition handling and minor things like, oh, graceful server shutdown.
static void Main( string[] args )
{
string localMachineName = Dns.GetHostName() ;
IPHostEntry localMachineInfo = Dns.GetHostEntry( localMachineName ) ;
IPAddress localMachineAddress = localMachineInfo.AddressList[0] ;
IPEndPoint localEndPoint = new IPEndPoint( localMachineAddress , PORT_NUMBER ) ;
using ( Socket server = new Socket( localEndPoint.AddressFamily , SocketType.Stream , ProtocolType.Tcp ) )
{
server.Bind( localEndPoint ) ;
server.Listen( PENDING_CONNECTIONS_QUEUE_LENGTH ) ;
while ( true )
{
using ( Socket connection = server.Accept() )
using ( NetworkStream connectionStream = new NetworkStream( connection , FileAccess.Read , false ) )
using ( TextReader connectionReader = new StreamReader( connectionStream , Encoding.UTF8 ) )
{
IPEndPoint remoteEndpoint = (IPEndPoint) connection.RemoteEndPoint ;
string line ;
while ( null != (line=connectionReader.ReadLine()) )
{
line = line.Trim() ;
Console.WriteLine( "Client says: {0}" , line ) ;
if ( string.Equals( "exit" , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
if ( string.Equals( "quit" , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
if ( string.Equals( "goodbye" , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
if ( string.Equals( "good-bye" , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
}
connection.Shutdown( SocketShutdown.Both ) ;
connection.Close() ;
}
}
}
}
If you want to buffer the stream, just decorate the NetworkStream
instance with a BufferedStream
:
using ( Socket connection = server.Accept() )
using ( Stream connectionStream = new NetworkStream( connection , FileAccess.Read , false ) )
using ( TextReader connectionReader = new StreamReader( new BufferedStream( connectionStream ) , Encoding.UTF8 ) )
{
IPEndPoint remoteEndpoint = (IPEndPoint) connection.RemoteEndPoint ;
string line ;
while ( null != (line=connectionReader.ReadLine()) )
{
line = line.Trim() ;
Console.WriteLine( "Client says: {0}" , line ) ;
if ( string.Equals( "exit" , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
if ( string.Equals( "quit" , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
if ( string.Equals( "goodbye" , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
if ( string.Equals( "good-bye" , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
}
connection.Shutdown( SocketShutdown.Both ) ;
connection.Close() ;
}
