示例

下面的代码示例使用 Socket 侦听传入连接。

// create the socket
Socket^ listenSocket = gcnew Socket( AddressFamily::InterNetwork,
   SocketType::Stream,
   ProtocolType::Tcp );

// bind the listening socket to the port
IPAddress^ hostIP = ( Dns::Resolve( IPAddress::Any->ToString() ) )->AddressList[ 0 ];
IPEndPoint^ ep = gcnew IPEndPoint( hostIP,port );
listenSocket->Bind( ep );

// start listening
listenSocket->Listen( backlog );

    // create the socket
    Socket listenSocket = new Socket(AddressFamily.InterNetwork,
                                     SocketType.Stream,
                                     ProtocolType.Tcp);

    // bind the listening socket to the port
IPAddress hostIP = (Dns.Resolve(IPAddress.Any.ToString())).AddressList[0];
    IPEndPoint ep = new IPEndPoint(hostIP, port);
    listenSocket.Bind(ep);

    // start listening
    listenSocket.Listen(backlog);

   ' create the socket
   Dim listenSocket As New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
   
   ' bind the listening socket to the port
   Dim hostIP As IPAddress = Dns.Resolve(IPAddress.Any.ToString()).AddressList(0)
   Dim ep As New IPEndPoint(hostIP, port)
   listenSocket.Bind(ep)
   
   ' start listening
   listenSocket.Listen(backlog)
End Sub

注解

Listen 导致面向 Socket 连接的侦听传入连接尝试。 参数 backlog 指定可排队等待接受的传入连接数。 若要确定可以指定的最大连接数，请检索 MaxConnections 值。 Listen 不阻止。

如果收到 ， SocketException请使用 ErrorCode 属性获取特定的错误代码。 获取此代码后，请参阅 Windows 套接字版本 2 API 错误代码 文档，了解错误的详细说明。 使用 Accept 或 BeginAccept 接受来自队列的连接。
