TcpListener.LocalEndpoint Propriedade

Definição

Namespace:

System.Net.Sockets

Assembly:

System.Net.Sockets.dll

Origem:

TCPListener.cs

Obtém o EndPoint subjacente do TcpListener atual.

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

public System.Net.EndPoint LocalEndpoint { get; }

member this.LocalEndpoint : System.Net.EndPoint

Public ReadOnly Property LocalEndpoint As EndPoint

Valor da propriedade

EndPoint

O EndPoint ao qual o Socket está associado.

Exemplos

O exemplo de código a seguir exibe o endereço IP local e o número da porta no qual o TcpListener está escutando solicitações de conexão de entrada.

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 );

const int portNumber = 13;

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());

        //Close the tcpListener and tcpClient instances
        tcpClient.Close();
    }

    tcpListener.Stop();
}
catch (Exception e)
{
    Console.WriteLine(e.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())

Comentários

Você pode usar a LocalEndpoint propriedade para identificar o adaptador de rede local e o número da porta que está sendo usado para escutar solicitações de conexão de cliente de entrada, depois que uma conexão de soquete for feita. Primeiro, você deve converter isso EndPoint em um IPEndPoint. Em seguida, você pode chamar a IPEndPoint.Address propriedade para recuperar o endereço IP local e a IPEndPoint.Port propriedade para recuperar o número da porta local.
