問題 C# 中的套接字 TCP IP 在停止前只收到來自客戶端的一條消息

Question

我的服務器在 tcp/ip 中出現問題，因為收到一條消息后不起作用。 我不知道使用 while 是否正確，以及如何放置。 有什么建議嗎？

謝謝

   my method()

        sdk = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        sdk.Bind(new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8052));
        sdk.Listen(10);
        Socket accepted = sdk.Accept();
        Buffer = new byte[accepted.SendBufferSize];
        int bytesRead = accepted.Receive(Buffer);
        byte[] formatted = new byte[bytesRead];
        for (int i = 0; i < bytesRead; i++)
        {
            formatted[i] = Buffer[i];
        }
        Debug.Log("\t Server" + "\n");
        string stradata = Encoding.ASCII.GetString(formatted);
        Debug.Log("-->" + "" + stradata + "\n\n");
        testo = stradata;
        //sdk.Close();   tried to uncomment 
        //accepted.Close(); tried to uncomment

您需要不斷地從套接字中讀取數據，直到讀取了您想要的所有數據

    sdk = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    sdk.Bind(new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8052));
    sdk.Listen(10);
    Socket accepted = sdk.Accept();
    Buffer = new byte[accepted.SendBufferSize];
    while (true)
    {
        // begin reading continually from the socket

        // Socket::Receive() will block until it gets some data
        // Exception handling required here for when client closes connection
        int bytesRead = accepted.Receive(Buffer);
        byte[] formatted = new byte[bytesRead];
        for (int i = 0; i < bytesRead; i++)
        {
            formatted[i] = Buffer[i];
        }
        Debug.Log("\t Server" + "\n");
        string stradata = Encoding.ASCII.GetString(formatted);
        Debug.Log("-->" + "" + stradata + "\n\n");

        // Need to add some exit logic here eg,
        if(stradata.Contains("EXIT"))
            break;
    }
    sdk.Close(); 
    accepted.Close();
