本文关键字：套接字 网络 系统 | 更新日期: 2023-09-27 18:12:09

好的，我已经使用以下代码连接到一个IP地址:

        IPAddress myIpAddress = IPAddress.Parse("10.10.15.200");
        IPEndPoint ip = new IPEndPoint(myIpAddress, 5001);
        Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        socket.Connect(ip);

我现在想监听套接字。当我输入socket。听着，智能感应系统说我需要输入待处理号码，这是什么意思?

此外，一旦我监听套接字，我如何捕获我正在"监听"的内容。

感谢约翰

你可以使用BeginAccept来读取到达你的套接字/端点的内容。

在MSDN上有一个完整的例子:BeginAccept Method 

// This server waits for a connection and then uses asynchronous operations to
    // accept the connection with initial data sent from the client.

    // Establish the local endpoint for the socket.
    IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName());
    IPAddress ipAddress = ipHostInfo.AddressList[0];
    IPEndPoint localEndPoint = new IPEndPoint(ipAddress, 11000);
    // Create a TCP/IP socket.
    Socket listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );
    // Bind the socket to the local endpoint, and listen for incoming connections.
    listener.Bind(localEndPoint);
    listener.Listen(100);
    while (true) 
    {
        // Set the event to nonsignaled state.
        allDone.Reset();
        // Start an asynchronous socket to listen for connections and receive data from the client.
        Console.WriteLine("Waiting for a connection...");
        // Accept the connection and receive the first 10 bytes of data.
        int receivedDataSize = 10;
        listener.BeginAccept(receivedDataSize, new AsyncCallback(AcceptReceiveCallback), listener);
        // Wait until a connection is made and processed before continuing.
        allDone.WaitOne();
    }
}

public static void AcceptReceiveCallback(IAsyncResult ar) 
{
    // Get the socket that handles the client request.
    Socket listener = (Socket) ar.AsyncState;
    // End the operation and display the received data on the console.
    byte[] Buffer;
    int bytesTransferred;
    Socket handler = listener.EndAccept(out Buffer, out bytesTransferred, ar);
    string stringTransferred = Encoding.ASCII.GetString(Buffer, 0, bytesTransferred);
    Console.WriteLine(stringTransferred);
    Console.WriteLine("Size of data transferred is {0}", bytesTransferred);
    // Create the state object for the asynchronous receive.
    StateObject state = new StateObject();
    state.workSocket = handler;
    handler.BeginReceive( state.buffer, 0, StateObject.BufferSize, 0,
    new AsyncCallback(ReadCallback), state);
}
