Exemplos

O exemplo a seguir demonstra o uso da Client propriedade. Neste exemplo, a transmissão está habilitada para o subjacente Socket.

// This derived class demonstrate the use of three protected methods belonging to the UdpClient class.
public ref class MyUdpClientDerivedClass: public UdpClient
{
public:
   MyUdpClientDerivedClass()
      : UdpClient()
   {}

   void UsingProtectedMethods()
   {
      //Uses the protected Active property belonging to the UdpClient base class to determine if a connection is established.
      if ( this->Active )
      {
         //Calls the protected Client property belonging to the UdpClient base class.
         Socket^ s = this->Client;

         //Uses the Socket returned by Client to set an option that is not available using UdpClient.
         s->SetSocketOption( SocketOptionLevel::Socket, SocketOptionName::Broadcast, 1 );
      }
   }
};

public static void Main(string[] args)
{
    if (args.Length < 1)
    {
        Console.WriteLine("you must specify a port number!");
        return;
    }

    UdpClient uClient = new UdpClient(Convert.ToInt32(args[0]));
    Socket uSocket = uClient.Client;

    // use the underlying socket to enable broadcast.
    uSocket.SetSocketOption(SocketOptionLevel.Socket,
                  SocketOptionName.Broadcast, 1);
}

' This derived class demonstrates the use of three protected methods belonging to the UdpClient class.
Public Class MyUdpClientDerivedClass
   Inherits UdpClient
   
   Public Sub New()
   End Sub
   
   Public Sub UsingProtectedMethods()
      
      'Uses the protected Active property belonging to the UdpClient base class to determine if a connection is established.
      If Me.Active Then
         ' Calls the protected Client property belonging to the UdpClient base class.
         Dim s As Socket = Me.Client
              'Uses the Socket returned by Client to set an option that is not available using UdpClient.
         s.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Broadcast, 1)
      End If
   End Sub
End Class

Comentários

UdpClient cria um Socket usado para enviar e receber dados em uma rede. As classes derivadas UdpClient podem usar essa propriedade para obter ou definir isso Socket. Use o retorno subjacente Socket se você precisar de Client acesso além do que UdpClient fornece. Você também pode usar Client para definir o subjacente Socket como um existente Socket. Isso é útil se você quiser aproveitar a simplicidade de UdpClient usar um pré-existente Socket.
