プロパティ値

Socket

基になるネットワーク接続を表す SocketA Socket that represents the underlying network connection.

次のコード例では、 Socket アクティブな接続を確認するための基になるを取得します。The following code example retrieves the underlying Socket to verify an active connection.

#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;
         }
      }
   }
using System;
using System.Net;
using System.Net.Sockets;

public class MyNetworkStream_Sub_Class : NetworkStream
{

    public MyNetworkStream_Sub_Class(Socket socket, bool ownsSocket) :
        base(socket, ownsSocket)
    {
    }
    // You can use the Socket method to examine the underlying Socket.
    public bool IsConnected
    {
        get
        {
            return this.Socket.Connected;
        }
    }

    public bool CanCommunicate

        {

            {
                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
         End If

注釈

から派生 NetworkStream するクラスは、このプロパティを使用して、基になるを取得でき Socket ます。Classes deriving from NetworkStream can use this property to get the underlying Socket. Socket Socket が提供するを超えるアクセスが必要な場合は、プロパティから返された基になるを使用し NetworkStream ます。Use the underlying Socket returned from the Socket property if you require access beyond that which NetworkStream provides.

注意

このプロパティは、このクラスまたは派生クラスを介してのみアクセスできます。This property is accessible only through this class or a derived class.
