TcpListener.LocalEndpoint Properti

Definisi

Ruang nama:

System.Net.Sockets

Rakitan:

System.Net.Sockets.dll

Sumber:

TCPListener.cs

Mendapatkan yang mendasar EndPoint dari saat ini TcpListener.

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

Nilai Properti

EndPoint

yang EndPoint terikat Socket .

Contoh

Contoh kode berikut menampilkan alamat IP lokal dan nomor port tempat TcpListener mendengarkan permintaan koneksi masuk.

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())

Keterangan

Anda dapat menggunakan LocalEndpoint properti untuk mengidentifikasi antarmuka jaringan lokal dan nomor port yang digunakan untuk mendengarkan permintaan koneksi klien masuk, setelah koneksi soket dibuat. Anda harus terlebih dahulu melemparkan ini EndPoint ke IPEndPoint. Anda kemudian dapat memanggil IPEndPoint.Address properti untuk mengambil alamat IP lokal, dan IPEndPoint.Port properti untuk mengambil nomor port lokal.
