Socket

基礎網路 Socket。

範例

下列範例示範 如何使用 Client 屬性。 在此範例中，會啟用基礎 Socket 的廣播。

// 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

備註

UdpClient 會 Socket 建立用來透過網路傳送和接收資料的 。 衍生自 UdpClient 的類別可以使用這個屬性來取得或設定這個 Socket 。 Socket如果您需要超過所提供的存取權，請使用從 Client 傳回的基礎 UdpClient 。 您也可以使用 Client 將基礎 Socket 設定為現有的 Socket 。 如果您想要利用使用預先存在的 Socket 簡單性 UdpClient ，這會很有用。
