Valore della proprietà

Socket

Oggetto Socket che rappresenta la connessione di rete sottostante.

Esempio

Nell'esempio di codice seguente viene recuperato il sottostante Socket per verificare una connessione attiva.

#using <System.dll>

using namespace System;
using namespace System::Net;
using namespace System::Net::Sockets;

ref class MyNetworkStream_Sub_Class: public NetworkStream
{
public:
   MyNetworkStream_Sub_Class( System::Net::Sockets::Socket^ socket, bool ownsSocket )
      : NetworkStream( socket, ownsSocket )
   {
   }

   property bool IsConnected 
   {
      // You can use the Socket method to examine the underlying Socket.
      bool get()
      {
         return this->Socket->Connected;
      }
   }

   property bool CanCommunicate 
   {
      bool get()
      {
         if ( !this->Readable | !this->Writeable )
         {

Commenti

Le classi derivate da NetworkStream possono usare questa proprietà per ottenere l'oggetto sottostante Socket. Usare il sottostante Socket restituito dalla Socket proprietà se è necessario accedere oltre a ciò fornito NetworkStream .

Nota

Questa proprietà è accessibile solo tramite questa classe o una classe derivata.
