Définition

Espace de noms:

System.Net.Sockets

Assembly:

System.Net.Sockets.dll

Source:

NetworkStream.cs

Obtient le Socket sous-jacent.

public:
 property System::Net::Sockets::Socket ^ Socket { System::Net::Sockets::Socket ^ get(); };

public System.Net.Sockets.Socket Socket { get; }

member this.Socket : System.Net.Sockets.Socket

Public ReadOnly Property Socket As Socket

Valeur de propriété

Socket

Socket qui représente la connexion réseau sous-jacente.

Exemples

L’exemple de code suivant récupère le sous-jacent Socket pour vérifier une connexion active.

#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 )
         {
            return false;
         }
         else
         {
            return true;

   ' the protected method 'Socket' to return underlying Socket.
   
   Public ReadOnly Property IsConnected() As Boolean
      Get
         Return Me.Socket.Connected
      End Get
   End Property
   
   ' You could also use public NetworkStream methods 'CanRead' and 'CanWrite'.
   
   Public ReadOnly Property CanCommunicate() As Boolean
      Get
         If Not Me.Readable Or Not Me.Writeable  Then
            Return False
         Else
            Return True

Remarques

Les classes dérivées de NetworkStream peuvent utiliser cette propriété pour obtenir le sous-jacent Socket. Utilisez le sous-jacent Socket retourné par la Socket propriété si vous avez besoin d’un accès au-delà de celui fourni NetworkStream .

Notes

Cette propriété est accessible uniquement par le biais de cette classe ou d’une classe dérivée.
