Question

你好我正在使用c＃进行tcp ip通信，当我的代码从IP监听时，它会给我错误消息，请求的地址在其上下文中无效。这是代码。

 TcpListener server = null;
        try
        {
            // Set the TcpListener on port 13000.
            Int32 port = 5555;
            IPAddress localAddr = IPAddress.Parse("10.3.0.234");

            // TcpListener server = new TcpListener(port);
            server = new TcpListener(localAddr, port);

            // Start listening for client requests.
            server.Start();

            // Buffer for reading data
            Byte[] bytes = new Byte[256];
            String data = null;

            // Enter the listening loop.
            while (true)
            {
                Console.Write("Waiting for a connection... ");

                // Perform a blocking call to accept requests.
                // You could also user server.AcceptSocket() here.
                TcpClient client = server.AcceptTcpClient();
                Console.WriteLine("Connected!");

                data = null;

                // Get a stream object for reading and writing
                NetworkStream stream = client.GetStream();

                int i;

                // Loop to receive all the data sent by the client.
                while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
                {
                    // Translate data bytes to a ASCII string.
                    data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
                    Console.WriteLine("Received: {0}", data);

                    // Process the data sent by the client.
                    data = data.ToUpper();

                    byte[] msg = System.Text.Encoding.ASCII.GetBytes(data);
                    Console.WriteLine("Sent Data:" + msg);
                    // Send back a response.
                  //  stream.Write(msg, 0, msg.Length);
                 //   Console.WriteLine("Sent: {0}", data);
                }

                // Shutdown and end connection
                client.Close();
            }
        }
        catch (SocketException e)
        {
            Console.WriteLine("SocketException: {0}", e);
        }
        finally
        {
            // Stop listening for new clients.
            server.Stop();
        }

实际上这个ip是在机器发送结果的机器中配置的。实际上我已经看到了很多相同问题的答案，但我不知道在哪里更改IPAddress.Any等可以通过编写代码如何通过tcp ip协议通信机器给我答案谢谢。

Answer 1

基本上是错误

请求的地址在其上下文中无效

表示计算机上的任何网络接口均未使用 IP地址。简而言之，您可能只需要使用IPAddress.Any

<强>〔实施例

server = new TcpListener(IPAddress.Any, port);

进一步阅读

TcpListener Constructor (IPAddress, Int32)

初始化侦听的TcpListener类的新实例传入连接尝试指定的本地IP地址和端口号。备注如果您不关心分配了哪个本地地址，请指定 IPAddress.Any用于localaddr参数和基础服务提供商将分配最合适的网络地址

IPAddress.Any

提供指示服务器必须侦听的IP地址所有网络接口上的客户端活动。

从其他计算机侦听数据时，请求的地址在其上下文中无效
