TcpListener::LocalEndpoint Property

Gets the underlying EndPoint of the current TcpListener.

Namespace:  System.Net.Sockets
Assembly:  System (in System.dll)

public:
property EndPoint^ LocalEndpoint {
	EndPoint^ get ();
}

Property Value

Type: System.Net::EndPoint
The EndPoint to which the Socket is bound.

You can use the LocalEndpoint property to identify the local network interface and port number being used to listen for incoming client connection requests, after a socket connection has been made. You must first cast this EndPoint to an IPEndPoint. You can then call the IPEndPoint::Address property to retrieve the local IP address, and the IPEndPoint::Port property to retrieve the local port number.

The following code example displays the local IP address and port number on which the TcpListener is listening for incoming connection requests.

try
{
   // Use the Pending method to poll the underlying socket instance for client connection requests.
   TcpListener^ tcpListener = gcnew TcpListener( portNumber );
   tcpListener->Start();

   if ( !tcpListener->Pending() )
   {
      Console::WriteLine( "Sorry, no connection requests have arrived" );
   }
   else
   {
      //Accept the pending client connection and return a TcpClient object^ initialized for communication.
      TcpClient^ tcpClient = tcpListener->AcceptTcpClient();

      // Using the RemoteEndPoint property.
      Console::WriteLine( "I am listening for connections on {0} on port number {1}",
         IPAddress::Parse( ( (IPEndPoint^)(tcpListener->LocalEndpoint) )->Address->ToString() ),
         ( (IPEndPoint^)(tcpListener->LocalEndpoint) )->Port );
