public System.Net.EndPoint LocalEndpoint { get; }
member this.LocalEndpoint : System.Net.EndPoint
Public ReadOnly Property LocalEndpoint As EndPoint

Eigenschaftswert

EndPoint

Der EndPoint, an den der Socket gebunden ist.The EndPoint to which the Socket is bound.

Beispiele

Im folgenden Codebeispiel werden die lokale IP-Adresse und die Portnummer angezeigt, auf denen der TcpListener eingehende Verbindungsanforderungen überwacht.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 );
        
try{
        // Use the Pending method to poll the underlying socket instance for client connection requests.
          IPAddress ipAddress = Dns.Resolve("localhost").AddressList[0];
      TcpListener tcpListener =  new TcpListener(ipAddress, 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 " + 
                                         IPAddress.Parse(((IPEndPoint)tcpListener.LocalEndpoint).Address.ToString()) +
                                          "on port number " + ((IPEndPoint)tcpListener.LocalEndpoint).Port.ToString());


Try

   Dim ipAddress As IPAddress = Dns.Resolve("localhost").AddressList(0)
  Dim tcpListener As New TcpListener(ipAddress, portNumber)
  tcpListener.Start()
  
   ' Use the Pending method to poll the underlying socket instance for client connection requests.
   If Not tcpListener.Pending() Then
      
      Console.WriteLine("Sorry, no connection requests have arrived")
   
   Else
      
      'Accept the pending client connection and return a TcpClient object initialized for communication.
      Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient()
      ' Using the RemoteEndPoint property.
      Console.Write("I am listening for connections on ")
      Console.Writeline(IPAddress.Parse(CType(tcpListener.LocalEndpoint, IPEndPoint).Address.ToString())) 
      Console.Write("on port number ")
      Console.Write(CType(tcpListener.LocalEndpoint, IPEndPoint).Port.ToString())
      

Hinweise

Sie können die LocalEndpoint -Eigenschaft verwenden, um die lokale Netzwerkschnittstelle und die Portnummer zu identifizieren, die zum lauschen auf eingehende Client Verbindungsanforderungen verwendet werden, nachdem eine Socketverbindung hergestellt wurde.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. Sie müssen dies zuerst EndPoint in einen umwandeln IPEndPoint .You must first cast this EndPoint to an IPEndPoint. Anschließend können Sie die IPEndPoint.Address -Eigenschaft aufrufen, um die lokale IP-Adresse abzurufen, und die- IPEndPoint.Port Eigenschaft, um die lokale Portnummer abzurufen.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.
